00:01So, morning, everybody, and welcome to Editing with ArcGIS 9.3.1, Tips and Tricks.

00:05My name is Colin Childs and my compatriot in arms here is Rhonda Glennon.

00:10I'm an instructor out of the Redlands office and I get to teach people how to use our software.

00:15And Rhonda is on the editing team as a technical writer and author and she does a lot of testing.

00:22And Rhonda's responsible for the help doc, and the help doc part of editing...

00:26...and also writing and developing the tutorials that you get to try out and practice.

00:31So, the two of us spend some time at User Conference helping, or trying to help, you with interesting tips and tricks...

00:40...that'll help you to be more efficient in working with editing and doing editing with ArcGIS.

00:46So our topics for this morning will be to talk a little bit about some productive editing techniques...

00:51...looking at some things you can do with respect to creating new features, editing existing features...

00:58...and some tips and tricks on editing coincident features and topologies.

01:03And our format is generally to introduce a tip and trick and then to do a software demonstration...

01:09...where we illustrate that tip and trick to you.

01:11So we'll introduce a couple of them, then do a software demonstration.

01:14And then we'll do some questions and answers at the end of the session if possible.

01:19It's a little distracting during the session to take questions, and we can get off track...

01:22...so please write those questions down, reserve them for us as well.

01:26Also, there should be some survey forms for this session.

01:29If you could fill those out when you're leaving later and just drop them in one of the boxes at the back...

01:34...that'll give us an idea of things we should work on for next year, and other areas that we should approach and tackle.

01:40So let's get started and take a look at one of the first tips and tricks that we'd like to introduce you to, and this is getting help.

01:47So using the help doc is a good way to get started and find information...

01:53...but often it can be quite, quite tedious sometimes to find things in the help doc.

01:59So while you're working, while you're busy working in an edit session or anywhere in our software...

02:04...you've got access to context-sensitive help.

02:07So at any point, if you take the What's This? button, which is the little question mark button...

02:11...you'll find in the top right-hand corner of your application, and you point at a menu choice or a button...

02:17...you're going to get some very quick, detailed information that's easy to read, right there and then as you're working.

02:24In a menu, a context menu for example, the same help can be gotten by using the Shift+F1 key on your keyboard.

02:31So you hover over a menu and you go Shift+F1 and it pops up with some help for you.

02:36So the What's This? option is very, very useful.

02:40Obviously the desktop help is also very useful, and usually you have to wade through things to find what you're after.

02:48I must tell you though, and since it's not a 10 session, but the 10 help is really awesome.

02:52They've got really cool search engines in them, and they've done a lot of work on reorganizing the 10 help.

02:59There are professional libraries and advanced libraries and entry level libraries...

03:04...and all sorts of really good organization in that as well.

03:07So it's good if you have some time, and if you don't have 10 installed, but you want to see it anyway...

03:12...go to the resources.esri.com page and you can get access to the online version of the ArcGIS 10 help. It's good.

03:19Now there are lots of training courses out there that you may want to consider as well.

03:23One of them that has been updated for ArcGIS 10 just recently is one called...

03:27...Data Production and Editing Techniques, the acronym DPET.

03:32And it's a project-based class, so you kind of do some stuff, you learn some new information.

03:36At the end of the day, you end up getting a raw project that you have to implement the data...

03:41...and the exercises that you've been working with during the day.

03:44So you actually get to practice, and put into practice, everything you've done.

03:48It's a good course. And Rhonda was one of the technical SMEs, or subject matter experts...

03:53...on developing that material. So, it's a good one.

03:57Now let's talk about working with the sketching tools and the editing tools and being more efficient with those.

04:04Well, shortcut keys are a really good tip for you here.

04:07So while you're working with something, you may want to very quickly pan and zoom...

04:11...but you don't want to go to the Tools toolbar to get to the Pan button or the Zoom button.

04:16So using keyboard shortcuts is a quick way to get to and do things while you're busy with something else.

04:23Things like the C key on your keyboard will let you pan.

04:27So you may be using the edit tools and doing something, and you hold C down...

04:31...and you can pan and release and do something back with the original tool again.

04:35So these keyboard shortcuts are really, really useful.

04:39And there is an exhaustive list of them. In fact, the help doc has a very good description of the shortcut...

04:46...the actual shortcut keys, and what that shortcut will do for you.

04:51I like using them a lot for navigating, so I don't want to go back to the Tools menu to do a pan or a zoom in or out...

04:56...I just go with my shortcut keys and while I'm working I can move around and do things.

05:03So, when working with the editing tools, you most of the time are working with sketches...

05:10...and you are creating new features or modifying features by modifying vertexes...

05:15...and you are creating features by adding vertexes to make a feature.

05:20But what a lot of people don't realize is that while you're using the sketch tools themselves...

05:25...a right-click during that session or that area where you're creating something with the Sketch tool...

05:31...will give you access to something we call a context-sensitive menu.

05:35And that context-sensitive menu will give you access to a series of sketch constraints.

05:41So you'll see the menu here. We're showing it to you on the right-hand side of the screens...

05:46...and the menu here is the one you would get as you were sketching with, for example, one of the Sketch tools.

05:51Now what that menu does is it says, Would you like to constrain the next vertex you're creating...

05:58...either parallel or perpendicular or at a specific angle or deflection angle...

06:03...or would you like the next vertex to be generated at an absolute x,y?

06:07So you're technically taking what you're doing as construction and manipulating the construction tool...

06:13...as needed through a right-click to get to these sketch constraints.

06:18So the things like lengths and directions and distances and angles and tangent curves are all options...

06:24...that you can get to via these sketch constraints with a right-click while you're sketching.

06:29Again, any help on those, Shift+F1. So hover over the menu choice, Shift+F1, and you get the help.

06:38So, many of you may be working with data that is still using feet and miles, or you may be working with data that is metric.

06:48Or you may be working with maps and information that you're entering that is in a combination of these.

06:54So some data is metric, some of it is in feet, and you potentially have to override...

07:00...or you have to do a conversion from one unit of measurement to the other.

07:04Well, not really necessary at all.

07:06Anytime you're using some of these sketch constraints, for example the length constraint...

07:11...you can type the length in, in whatever unit you wish, and associate or add...

07:16...the acronym for the unit that that length is in, and our software will automatically do the conversion for you.

07:23So you'll see the table points out some of the different varieties of units and the acronym or abbreviation...

07:30...that you can add to that length or value and it'll know it's got to convert from that unit that you're entering in...

07:37...to the unit, to the actual map unit that you may be working in.

07:41Obviously, this is only going to be important if your map unit is different from the unit you're entering a value in.

07:48So in the example there, our data is in fact in feet.

07:52Our map units are in feet, as we can see from the lower end of the application, but we're entering a distance in meters.

07:58So we type the value, an M for the abbreviation, and it'll do the conversion internally for you...

08:04....from meter to feet, to generate the new line or segment that you're creating.

08:11So working with sketches you have access to a series of sketch tools in 9.3.1.

08:17You've got the common one people call the Pencil Sketch to generate new features.

08:22But there are sketch tools to create a vertex at the intersection of two lines for example.

08:29And there are other sketch tools that'll let you create vertexes and features...

08:34...or generate features, at tangent curves and other forms.

08:38Well, one of those sketch tools is called the Trace tool.

08:44And what the Trace tool will do is it'll allow you to take existing, selected features...

08:50...and use them as a basis from which to create new features in a target feature class or layer.

08:57So in the example you see here, we have several parcel boundaries selected...

09:01...and what I want to do is create a new road centerline to follow the curvature of those parcel boundaries.

09:08So I preselect the parcel boundaries, I make sure my target layer is the centerline layer...

09:14...and I begin by creating a new feature, but instead of using the standard Pencil Sketch, I use the Trace tool.

09:22And the Trace tool will clone, if you like, the coordinates from the selected feature to generate the new feature for me.

09:30In the example you see there, however, we wanted to offset the new geometry we were creating by...

09:37...with the Trace tool, we wanted to offset it away from the original selected feature's geometries.

09:42So by holding the O key down on your keyboard, there are additional options to the Trace tool that you have access to.

09:50And the dialog you see above there is actually showing you some of those options where you can set a positive...

09:56...or negative offset from the selected features to trace, and then you can also define the curve.

10:02Is this going to be a beveled or a mitered or a rounded curve when I generate some features?

10:08So that's a quick way to, in a way, clone existing geometry to create something new, the Trace tool.

10:17So modifying selections.

10:18When you're working with a lot of features and you're editing multiple feature classes at the same time...

10:24...sometimes you want to do a selection and you inadvertently get more features than you intended.

10:30So you may have in the...you may have had roads and other types of things all below...

10:35...and all...you may have made a selection and you've got, say 20 features selected.

10:40In fact, this example here, we're showing where we have multiple features selected...

10:44...or we also have the problem where we don't know which layer we're selecting from.

10:50So in the upper portion here, what you're seeing is, we're using the Selection tab...

10:55...and with the Selection tab, instead of having the normal tab, we use the Selection tab...

11:00...you can turn layers that you want to select from, on and off.

11:04So it's a quick way while editing, to turn layers on and off, hold the Ctrl key down, turn them all off from selection.

11:11Hold the Ctrl key on, it'll turn them back. So you click on one of them with the Ctrl key down, they all get turned off.

11:17If they're all off, hold your Ctrl key down, click and they'll all get turned on again.

11:22So the top graphic is illustrating the Selection tab and how you can make certain layers selectable or others not...

11:30...and the highlighted one, the one in bold, is in fact the one that you may currently have selected features from.

11:37So this is selection. The bottom graphic here is describing when you have multiple features selected...

11:44...and you want to potentially deselect one of them, or navigate, or copy, one of them.

11:50So in the Attributes dialog, if multiple features have been selected...

11:55...you can deselect a record, a feature, in the Attributes dialog from a selected set.

12:01Also, in the top graphic again, with the table of content, anytime you have selections out of a layer...

12:08...a right-click on that selected layer will give you the option to switch selection to those records...

12:15...that are not selected of the layer, to clear the selection, zoom to the selected, and so on.

12:20Now here's where I was getting to a little earlier. I got mixed up with the slides, by the way.

12:25If you have multiple features in the same spatial location...

12:29...for example, here we have a line feature and two polygon features and we selected.

12:34But we didn't want to select the line. We actually wanted to select the polygon.

12:38But we didn't want to select the small polygon. We wanted to get the big one below it.

12:42Well, that's problematic because I want to edit out of all three layers.

12:45I have them all three active, but how do I get to focus my selection on the big polygon or not on the line?

12:53Well, if you issue a selection like that, and multiple features are in the same spatial location...

12:59...holding down the N key on your keyboard will cycle you through all geometries that are selectable at that location.

13:08So the first time I held my N key down, I got the road.

13:12Hold my N key further, I get the small polygon.

13:15Hold my N key again, I get the big polygon.

13:18So I'm essentially cycling through all associated geometries at one specific geographic location that I may be working on.

13:29So that's an example of working with features that may be overlapping...

13:33...where I don't want to turn the layer off from selection.

13:36I want to keep multiple layers on, but then cycle through the selected features.

13:42Now, another area you may want to be aware of is, is that while you're editing or modifying features...

13:48...something that often happens is you inadvertently move something without intending to.

13:53So you select something, but you don't realize you've selected more than what you needed to...

13:58...you do a move, and boom, things move that you didn't intend to.

14:02So a way to prevent that is to go to your Edit menu, to Options.

14:06And on the Edit Options you have the choice to set what is called the Sticky Move Tolerance.

14:12Now the Sticky Move Tolerance is a distance, in map units, that you physically have to...

14:17...or implicitly have to move something before that move stays.

14:23So it's called a Sticky Move Tolerance, because you have to go beyond the distance you've specified...

14:28...for Sticky Move, in order to actually move something.

14:32So, in a way, it prevents you from unintentionally moving things that may have moved...

14:39...if you had not set a Sticky Move Tolerance.

14:42So this is a way that we help you a little more to not make mistakes, or not do things you didn't intend to.

14:50Snapping is another area that many people have some confusion with and ask us a lot of questions about.

14:56And you know that you can create several snap agents when you are working.

15:01You can set up a snap agent for each layer and you can say that you want to snap vertexes...

15:05...or you want to snap to the edge of something.

15:08So you can create all sorts of different snap agents.

15:11But when working with these snap agents, it's kind of nice to be able to see which one is being used at that point in time.

15:19So by turning on the SnapTips, as you're editing, and this is the middle graphic that I'm talking about here is...

15:26...as you're editing and you're about to move a vertex or add a vertex...

15:31...the SnapTip will show you which of the snap agents...

15:34...in this case Demo Buildings Vertexes, are being snapped.

15:39You'll also see that in the lower end of the application, and this is the upper graphic...

15:43...in the lower end of the application, it'll also give you some standard readout saying, this is the layer name...

15:49...and this is the snap type, or agent, that is currently being used or will be used at that point in time.

15:57So this is just a...two options.

15:59Setting up the SnapTips and then watching the lower end of your application in order to see which snap agent is used.

16:06Another area that people often ask us is, How do I know how big the snap distance is?

16:11Because I typed it in under the Edit Options menu, and I typed it in in pixel units...

16:15...or I typed it in in map units, and I really have no conception of the size of that snapping area.

16:22So what we recommend you do is, as you're editing and you want to visualize or see how big the snapping area will be...

16:29...that things will snap together, is hold your T key down on your keyboard.

16:33The T key will give you, or visualize for you, the actual snapping distance itself.

16:39So for those of you that set snapping, and I'm sure you pretty much all do...

16:43...in ArcGIS 10, your snapping is only in pixel units now, not in map and pixel units.

16:50And the reasoning behind that is, is that quite a number of things could go wrong in map units...

16:54...if you are zooming in and changing resolution.

16:57So in ArcGIS 10 it's primarily just in pixels now.

17:01I shouldn't tell you this either, because Rhonda's going to murder me...

17:03...but snapping is way cooler in 10. Way, way cooler. It's always on by the way.

17:09So a lot of people have asked us, you know, When I use the Measure tool to measure things...

17:13...can I have the snapping happen so it snaps to something?

17:16Well in 9.3.1 that wasn't possible, but in 10 it is, because it's always there.

17:21It's always active. So it's much, much nicer.

17:24Okay, so controlling how features snap. How do we control how the features snap?

17:28Well, first of all we need to set the snap tolerance under the Editing Options.

17:32And there is a customization tool, a little Customize tool, and you'll see that over there at the top, that you can create.

17:41You can add it to a toolbar and you can have the ability to visualize or show the snapping tolerance visually if you wanted to.

17:49Now the Snapping Environments window, which is the one at the bottom of the graphic.

17:53At the bottom is where you generate all those different snap agents.

17:56So you select the layer and you say which snap agent, vertex, and end of that layer you'd like to create.

18:03So in the example here, we've actually got three separate snap agents associated to two different layers.

18:09Within that snapping environment, something else a lot of people don't know is, is you can prioritize your snapping.

18:15So you can take the layer, like parcel, hold your cursor on it, and drag it up in the list...

18:22...and that way you prioritize the layer for snapping.

18:25So parcel snapping will take precedence over street and zoning snapping that might have been set.

18:31So that's a way where you can go ahead and prioritize snapping.

18:35Shortcuts. If you want to temporarily suspend your snapping, hold your Space key down while you're editing...

18:40...and that'll say, Hey, I'm not going to use any snapping at this point at all.

18:44And V, the V key on your keyboard is pretty nice as well.

18:49So as you're editing and you want to view vertexes that you potentially could be snapping to...

18:54...hold your V key down on your keyboard and it'll show you all the vertexes within the current extent...

19:00...and then if you're busy creating a sketch, you can move to one of those vertexes to invoke the snap.

19:06One more thing about snapping.

19:07You can override your snapping by sketch constraints.

19:11Remember you get to those by right-clicking while you're sketching.

19:15So if you right-click while sketching, you have the choice to do Snap to Feature.

19:19That's one of the sketch constraints.

19:21And if you choose that one, you have four additional, or different, options you can pick from.

19:26The first two and the last one are actually common ones...

19:29...'cause those are the same ones you get to do as existing snap agents.

19:33But the middle one is unique to the sketch constraints, Snap to Midpoint.

19:39So you'll notice that if you go back to the snapping environment here, you don't have a midpoint option right there.

19:45But as you are doing the sketching and you right-click and use the snapping over there...

19:50...with Snap to Feature, you have the Midpoint option available.

19:54All right. So let's switch over and let's show you some of these in practice.

20:02We're on?

20:03All right. So in this map I have some parcels...

20:06...and those of you guys in natural resource management who get really tired of seeing parcels demos...

20:11...let me tell you that the ArcGIS 10 tutorials are all built using data from Zion National Park.

20:17So I hear you. I hear what you're saying.

20:20I came from a natural resource management, but bear with me through one more parcel demo.

20:26So in here I have a neighborhood and I'd like to add in some streets.

20:30And the streets are being shown by these gray lines.

20:34So to do this, I'm just going to do the normal start an edit session.

20:40And by the way, everything that I'm going to show you here today can be done using shapefiles...

20:45...and using an ArcView license, unless I specify otherwise.

20:50So when I'm going to create my features here, the first thing I want to do is just kind of set up my snapping environment.

20:58So I'm going to go to the Editor menu on the Editor toolbar, go down to the Options, and turn on SnapTips.

21:06In ArcGIS 9, they are not on by default, but they will be in ArcGIS 10.

21:13And then I'm going to actually set up my snapping environment.

21:17So go to the Snapping menu and it opens the Snapping Environment window.

21:22And by the way, if you have a dockable window that you don't want to dock...

21:26...you can hold down the Ctrl key and that will allow it to float.

21:31So let's dock this here at the bottom, and let's resize it, and I'm going to turn on snapping for my Streets layer...

21:42...and let's go for some Vertex, Edge, End for my streets.

21:47And also I'm going to be working with some parcels, so I'll turn on some, maybe some edge snapping for parcels.

21:53And I'll just leave this open so I can change my snapping environment while I'm working.

22:00We'll go ahead and start creating our feature.

22:02I've got to make sure I set my target, 'cause I've been using ArcGIS 10 for so long...

22:07...and it's just so easy when you create a feature, you say, I want to make that feature...

22:11...instead of accidentally creating it in some other layer.

22:15So, be sure to set my target to Streets here, and now I'm snapping, and you see that when I snap...

22:20...I get this little tip that says I'm snapping to the Streets layer and using the End snap type.

22:28I'll click to add my first vertex, and now this segment here, I want to add parallel to my existing one.

22:36So there's a couple ways I can do that. I'll just right-click over it and say parallel...

22:42...or I could also hold down the Ctrl key and press P.

22:47And so it's going parallel to the feature that I've right-clicked over.

22:52So now you see that I'm constrained to being parallel.

22:55If I decide I don't want to be constrained, I can press the Esc key and that'll clear it out.

23:01So let's actually add a length for this segment too.

23:04So I could also right-click or I'll use the shortcut, Ctrl+L...

23:08...and it brings up this dialog that allows me to enter the length for my segment.

23:13So, because my map units are in meters, ArcMap automatically interprets what I'm entering as being as meters as well.

23:22So we'll make it 15.4 meters, and it creates the vertex where the segment would be 15.4 meters.

23:28So while I'm in the sketch, I can actually change tools and continue my sketch.

23:32So now that I'm over here, I have some other features that I could use to snap to, to create the rest of my line.

23:45So I'll go over here and I'm going to change over to the Midpoint tool.

23:48And the way Midpoint works is it allows me to drag a line and it will place a vertex in the middle of that line.

23:57So you see as I drag it I have this black box and that's going to be where the vertex is placed.

24:04So we'll snap to the other edge and maybe we'll make another vertex and do that again.

24:12You see, well, that's okay, but I have this curve over here...

24:16...and I want to capture the curve instead of just making kind of straight segments.

24:21So I'm going to switch over to the Trace tool now.

24:24And the way the Trace tool works is by selecting some features and then the Trace tool will trace on those edges.

24:32So I need to select features, but if I drag a box right now I'm going to select who knows what.

24:38So I'm going to go over here on my Selection tab of the table of contents, and I only want my Parcels layer to be selectable.

24:46So I can right-click the Parcels and say, Make this the only selectable layer...

24:51...and you see it unchecked all those layers and checked Parcels.

24:55So now when I drag a box over here, it's only going to select the parcels.

25:05And we'll go over to the Trace tool and I can start my trace.

25:12You see, I clicked here, and notice it's tracing right on top of this edge, but really I wanted an offset.

25:18So I know that my offset's going to be about 7.5 meters...

25:22...so the way to enter that is to press the O key to bring up the Trace Options dialog.

25:28And it will allow me to enter that offset.

25:31So we'll make it 7.5. Again this is going to be entered in map units...

25:35...and I can set my corners to be rounded, and I click OK.

25:41And notice now that I'm tracing at an offset.

25:44If it turned out that offset were on the wrong side, I could just press the Tab key and it will switch sides.

25:51Effectively this is just adding a negative in front of my offset.

25:55We'll trace over here, I'm going to snap to the end, and finish the sketch.

26:01And notice that I used three different ways to create this one feature.

26:06So don't forget that you can switch tools while you're tracing and while you're creating features.

26:13So now we'll go over and I want to make another feature up here.

26:17So we'll switch back to the normal Sketch tool, snap to our edge...

26:22...and again I want to make it parallel, so I'm going to right-click over the line I want to be parallel to, and press Ctrl+P.

26:29So in this case, I've been given a measurement that's in feet, and since my map units are in meters...

26:35...I can tell ArcMap to convert them for me.

26:38So I'm going to enter my length, Ctrl+L, and let's say my measurement is 282 and it's in feet.

26:45So all I do is I type this distance units abbreviation.

26:48ArcMap, behind the scenes, will automatically convert this for me.

26:52And I press Enter and it creates the feature.

26:56We'll make one more. In this case, we'll make it perpendicular.

27:01And then we'll finish the sketch.

27:03So now I have two features over here, but I have this nice curve that I want to capture.

27:08So a tool that we allow you to create a curve with pretty easily is called the Fillet tool.

27:14And it's on the Advanced Editing toolbar.

27:18Again, this is going to be available with ArcView as are all the other tools on the Advanced Editing toolbar.

27:23And so the way it works is, I click the first line that I want to use for the curve...

27:30...I click the second line, and it draws this curve in between.

27:34If I want to set options for it, just like Trace, I can press the O key.

27:39And here I've set it so that we'll trim off the existing segments where I click.

27:44So you see, I'm snapping here, and we'll go ahead and click to create this curve between the features.

27:52So now I have three features and I want to merge them into one so I have one line.

27:58So just go to the Editor menu and go over to Merge, choose the feature to merge into.

28:04This'll be the one that supplies the attributes.

28:07In this case, it doesn't really matter, 'cause they all have the same attributes.

28:10We click OK, and now I have one long feature.

28:15And we'll fill in our last road here by snapping parallel and snapping on the other side.

28:23So we've filled in all of our lines...

28:25...but let's say that our organization recommends that each line be split at its intersection.

28:32So like everything else in ArcGIS, there's a lot of different ways to do it.

28:37So the simplest is using the Split tool.

28:42So if I select the line I want to split, go to the Split tool on the Editor toolbar...

28:47...it's using the snapping environment right now, and you see I get a SnapTip to indicate where I want to...

28:54...where it's going to be splitting. I click it and now I have two features here.

29:00So that's okay, but we have a lot of lines here that we need to split...

29:04...so like everything else, there's probably a better way.

29:07So depending on your license, you may have other options for splitting your lines.

29:12So I'm going to use a method now that is available only with ArcEditor and ArcInfo licenses.

29:22So we'll turn off my selection for my parcels and I'm going to go add my Topology toolbar.

29:31You don't have to have a topology to use this tool, but you do need to have ArcEditor or ArcInfo.

29:38So I'm going to select all the lines that I want to split, and then go to the Planarize Lines command.

29:47And it brings up a dialog box where I can enter a tolerance.

29:51In most cases, you should just accept the defaults.

29:54We'll press Enter, and now you see it's split every one of these lines at its intersections.

30:01So when you're working in ArcMap, how would you know which is the best way?

30:06Well, quickly you can just click the What's This? button and click a tool...

30:12...and it will bring up a little bit of a help topic here that shows you what a tool does specifically.

30:19And this is really useful, because you don't have to stop your work and go into the help and that sort of thing.

30:24And it's also useful if you have a tool that you just can't figure how to get enabled.

30:29Like, Planarize Lines, for example. If I want to use it, but it's disabled, why might that be?

30:35Well, it says it's disabled if no line features are currently selected.

30:39It's also disabled if you're using ArcView.

30:42So for those of you using Windows 7 or Windows Vista, when you try to get this help...

30:47...you'll need to install a patch from Microsoft.

30:50There's a window that comes up that says, For more information, click here from Windows.

30:55So make sure you install this patch to make it work.

30:59In addition, in the help we also do have a lot of topics on splitting lines.

31:06So one more thing I want to show you in this area is, let's go back to the Display tab...

31:11...and you see I have one data frame here called Editing and I also have another data frame down here called Imagery.

31:19So let's say I want to view these simultaneously.

31:21Maybe I have multiple monitors on my computer.

31:25So what I can do is, on the...this is the Tools toolbar here. There's a tool here called the Create Viewer Window tool.

31:32And I just drag a box and it opens up a view of my data frame.

31:40So this is pretty cool, 'cause I can actually interact with it.

31:42I can pan, I can zoom. I can actually edit inside of this window.

31:46So it's kind of like having two ArcMaps at the same time.

31:50And if I go down here to my other data frame, I'll activate it, and I'll also do the same thing over here.

31:58So another way to get a viewer window is to go to the window Viewer menu.

32:05And now if I go back over here to my editing and activate it...

32:09...you see that I now have all these different windows that I can work with in ArcMap.

32:17And it's really useful for multiple monitors, especially, 'cause you can just resize this...

32:22...and make it the whole size of your monitor and get another view.

32:26So let's go back to the slides now. All right?

32:31Thank you, Rhonda. So I guess you see the power of seeing a demonstration.

32:35See everything's in practice and you can see how it gets put together.

32:38Now let's take a look at a few additional things that we get a lot of questions about.

32:43So many of you may be in the process of migrating data from shapefile...

32:49...or other formats into geodatabases and into feature classes.

32:53And sometimes you go through import tools to import the data into a feature class...

32:58...or you may use an export tool to export from the data format into a new geodatabase feature class and so on.

33:06But what if you have some spatial data that you would like to copy, and put, or plug in...

33:12...somewhere inside of an existing feature class that you might be editing inside of an edit session?

33:19So a lot of people don't realize is that ArcMap's Copy and Paste tools work just as well.

33:24So select the features that you want to paste or copy into a target layer that you're editing.

33:31So you copy them with the Copy tool, make sure your target layer is the correct layer you want to paste them into...

33:38...and use the Paste button in ArcMap. It's as simple as that.

33:41If the geometries are the same, which is what they need to be, polygon to polygon...

33:45...Copy/Paste works perfectly fine if the features you're copying in have the same schema...

33:51...in other words, the same field names and field definitions, they'll bring all the attributes across as well.

33:57This is a very common workflow for people working with CAD data.

34:01They may display the CAD data inside of ArcMap, select something they want to grab out of the CAD dataset...

34:07...they select it or copy it, and copy it and then paste into a target feature class that they may be working on.

34:13A few pointers here though, that sometimes when you're copying features...

34:18...the source data may be at a different resolution or scale.

34:21And that's particularly common, for example...

34:24...maybe with CAD data, you may actually have it at a different scale to the scale that you're working on.

34:29So the Copy/Paste tools here might not necessarily be appropriate...

34:34...but on the Advanced Editor toolbar there's a Copy Features tool...

34:38...which will allow you to take the selected features you have and copy those features into your target layer...

34:44...but at the same time, size and position them.

34:47And that's what you see in the little graphic that we're showing you here...

34:50...is some CAD data that needs to be fitted into a new residential subdivision that has been laid out and designed.

34:58So Copy Features tool if you need to size or scale the features you're copying over...

35:04...or just the standard Copy/Paste will work very, very well and very easily for you as well.

35:10So a few more things that people ask us a lot about when they come down to the islands are...

35:15...you know, How do I make a donut hole in an existing polygon?

35:18So in other words, How do I cut out a piece for a lake or for some other reason.

35:23And it's pretty simple to do. Have your underlying feature available and ready...

35:28...digitize or create the new feature you want to cookie-cut or donut out, select that feature...

35:35...that whole feature that you'll...the cookie-cut area that you want to cut out...

35:40...and then go to the Editor menu, and on the Editor menu is a choice called Clip.

35:45When you bring up the Clip option, the thing you need to be careful with here is...

35:49...is to check on the Discard area that intersects option from the menu.

35:53And what it'll do is it'll take the selected feature and essentially cut it out...

35:59...and create a donut hole in the underlying feature below it.

36:03And that's an example of donut holes.

36:06Now anytime you create or add or make a donut hole in a feature, you're generating a multipart feature.

36:13So the one that you cut out of becomes a multipart feature...

36:17...and in that case you can see it's multipart if you take a look at the Edit Sketch Properties.

36:22And this graphic is showing you the Edit Sketch Properties and you'll see that that particular feature there...

36:27...the big square polygon, consists of parts 0 and 1, two parts.

36:33So, another question we get is, If I have a donut, how do I delete it?

36:37Pretty simple. Go to the Sketch Properties, right-click on the part number, 0 or 1, hit Delete, and it's gone.

36:45In this case, you might want to select - the 0 part is the actual donut. So you right-click on it and delete it.

36:53If you take a look at the sketch tool, the Sketch Properties tool, by the way...

36:57...it's here where you can get to the actual x,y pairs of the vertexes that make up the features.

37:01So anytime you want to modify at that level, you can do it in the Edit Sketch Properties as well.

37:09So when working with line features, generally when we're creating things like geometric networks...

37:16...or we're working with transportation networks...

37:18...we're very interested in the directionality of the linear features.

37:22Rivers, water pipelines, and so on.

37:25They need to be aware of the directionality and you want the directionality to be correct.

37:30So we often get questions related to, Well, how do I know the direction of my line? How do I see it?

37:36In other words, How can I figure out or visualize what is the from and what is the to direction?

37:41So my suggestion here for you is, is to use a symbol with an arrow.

37:45Some of the symbols allow you to display arrows at the begin or the end...

37:49...or along the middle of the line feature you're symbolizing...

37:52...and in this way, you can visually see the directionality of a line.

37:57If you need to flip or switch the directionality around, on the Edit Sketch context menu...

38:04So remember, select the feature for modifying, right-click...

38:07...there's an option in that Constraint menu which is called Flip...

38:11...and that'll flip the from and to, to the to and from, or the other way around for you.

38:16For bulk processing of multiple features, there is a VB6 developer kit sample available from the Resource Center...

38:26...which you can then implement as a tool, and this is a bulk flip of selected lines.

38:32So if you select a multiple of line features, you can do a flip or a bulk flip of those lines.

38:38So those are some things to think about with line features.

38:41So I've kind of mentioned already that if you need to get to the x,y coordinates that make up the geometry of your spatial features...

38:49....maybe you want to modify a line's curvature or so, by changing the actual x,y pairs...

38:56...the Edit Sketch Property menu is where you would go to.

38:59In this case, right-clicking on any of the x and y pairs will give you access to them...

39:05...and you can type in the new x,y pair values there if you wish to.

39:09If your features are m-aware or z-aware, you also have access via the same menu to the measure, or m-value...

39:18...or to the z-value if you have z-values as well.

39:21In case you're curious, m-values, or measure values...

39:24...are used when you do dynamic segmentation and are interested in linear referencing of line features.

39:30It's like having an alternative measure value such as length or time...

39:35...or fuel usage for road, for example, as an additional property for your spatial data.

39:41If you're interested in that, linear referencing is the topic to look at in the help doc.

39:45So, the next thing you might want to be looking at is updating attributes.

39:50Now, updating attributes can be done in several different places.

39:54You can either update the attributes in the Attribute table, or alternatively...

39:58...you can update the attributes using the Attribute Editor dialog while you're editing.

40:03So if you select some features, you can click the Open Attributes window.

40:07It'll open up the attribute's Editor dialog during your edit session, and you can go to...

40:13...if you like, the individual feature records, or attributes, like that.

40:19So you can either go to the individual features that you've selected and modify their attributes.

40:24Or, as an alternative, if you want to do a kind of batch update...

40:29...rather than select the individual features themselves, is select the layer name at the top of the Attribute Editor.

40:36And if you select the layer name and you make an edit change there...

40:39...it cascades to all the selected features that you've currently got selected.

40:44So that's a pretty nice way of modifying or updating edits.

40:48Something else that people kind of forget too, is when you have the attribute table open...

40:53...there is an option called Find and Replace.

40:57And sometimes if you've made a typo somewhere or you want to create...change something from lowercase to uppercase...

41:03...Find and Replace is a very quick, easy function in the Table dialog, to modify and change an attribute.

41:12I just thought about that one, by the way.

41:14So you can do that from the table itself if you wish to.

41:17Now, working with tables, when you work with a table, remember you can hide fields.

41:22You can make certain fields fixed in position.

41:25You can also scroll down and across the columns very easily.

41:30And there's a whole bunch of shortcuts to do this.

41:33So you can either use mouse keys or keyboard shortcuts.

41:37And the help doc has a very extensive list of these table navigation shortcuts.

41:43So just as you can have shortcuts for editing, like panning and zooming...

41:47...you also have similar shortcuts for when working with the Attribute table.

41:52Now something I particularly like about the attribute tables, is they've got a new option.

41:57Well, it's been around for awhile, but with 9.3, it was added with 9.3 for Calculate Geometry.

42:03Now, a lot of times I'm working with my spatial data...

42:06...my area or my perimeter is calculated in feet or in meters, but I want to know the area in hectares.

42:13Or I'd like to know the total acreage of a polygon feature.

42:17And in the past I had to add an empty field...

42:20...and I had to know what the expressional formula was to calculate acreage or hectare.

42:25Well, I can add an empty field now, right-click and use Calculate Geometry...

42:30...and the Calculate Geometry dialog will give me the ability to fairly quickly calculate what I need to know...

42:36...the area or the perimeter, and you can even use this dialog to extract out the x- and y-coordinates...

42:42...of a point feature to two separate fields if you want to.

42:46So this is pretty nice, something that you do very often and you need quite commonly.

42:52Let's switch over to Rhonda and take a look at a demonstration of these. Oops. There we go.

42:59Okay, so in this area, I have some parcels with some new buildings that have come in from another layer.

43:06But I want to get them into my main Buildings layer.

43:09So you see the buildings are in red here. They're in a layer called New Buildings.

43:13If I turn that off, you see I don't have any gray buildings in my Buildings layer.

43:18So a simple thing I can do is just copy and paste.

43:21Now I'll go back over to my Selection tab, make sure that the New Buildings layer is selectable, and I will drag.

43:33Simply go to the Copy command.

43:37Make sure my target is my regular Buildings layer, and just say Paste.

43:44And now you see they are pasted right on top of my existing one.

43:48So if I needed to put them in another location or if I needed to scale them...

43:53...I could use the Copy Features tool on the Advanced Editing toolbar.

43:57In this case, it worked really nicely, just to copy and paste them.

44:03So now that I have these buildings in here, I want to work on this polygon containing...this is a lake inside of a park.

44:15So what I want to do is manipulate this polygon in the middle here.

44:21So we'll go back over to our selection.

44:23And I'm going to set my Parks and my Lakes to be selectable...

44:28...and you notice here, I just clicked the map and I got the top feature selected.

44:33But what if I wanted the park underneath it?

44:36I press the N key and you see it cycles through the selection.

44:40And notice over here on the Selection tab, it's changing the bold and the number of selected features as I do that.

44:50And actually, in ArcGIS 10, this is a lot nicer, because instead of just randomly cycling through kind of like that...

44:57...I get this visual pop-up that allows me to click and choose the exact feature I want from a drop-down list.

45:06So let's say that in this lake, maybe the water level has lowered and there's now an island that's visible in the middle of it.

45:14So how do I create that island?

45:17I'm going to use the Cut Polygon Features task and then draw in the sketch of the location of the island.

45:26So you can use Cut Polygon Features for both cutting holes in polygons...

45:30...and also just slicing them in half and making multiple features that way.

45:39So let's go over to the Sketch tool and just start drawing in my sketch.

45:49So the reason that actually worked was because I had made sure that my feature closed in on itself.

45:58But what happens if I did something like this?

46:02How many of you guys have gotten this error that says "The Cut Polygons task could not be completed, et cetera"?

46:08So one thing to do is make sure that you turn on edit sketch snapping on the Snapping window.

46:17So you see that when I close my polygon here, I get that pop-up that says 'Edit sketch vertices.'

46:25So it's just one way to make sure that I've closed the line and I don't get that error message.

46:32So let me turn off this Parks layer so you can see kind of what's going on here.

46:38So now I have two features. I want to delete that center one so I'm just left with my outer shell.

46:46And the way this is implemented in ArcMap is that this is, again, called a multipart polygon.

46:51Multipart polygons don't have to have holes in the middle.

46:54They can also be features like maybe the islands of Hawaii or something like that...

46:58...where it just references one row in an attribute table.

47:05So how do I work with this?

47:06Well, I can go into my Sketch Properties dialog and from here, if I wanted...

47:12...I could change my x- and y-coordinates, and z- and m-values, and that sort of thing.

47:17But, let's say for example, that now the water level's back up.

47:20We had a nice rain and a nice wet season. So how do I delete this?

47:24It's just as simple as choosing the correct part. You notice the part flashes.

47:29And I just right-click and say Delete, and now when I finish the sketch, it's gone.

47:35So in ArcGIS 10, this is a lot nicer because we actually have more interactive selection ability.

47:41So I can actually select the part that I want to work with using the map...

47:45...instead of having to scroll through that list on the Edit Sketch Properties window.

47:50So when you guys go home and you've forgotten all these steps...

47:53...let me remind you to look at the "Common polygon editing tasks" section of the help.

47:59So if you scroll down, it describes many of the tasks that you guys ask us about...

48:05...and in fact, some of these have even come from the User Conference.

48:09A couple of years ago we had a user come up to us and said...

48:11...How do I reshape a polygon to match a line that doesn't overlap it?

48:16So we actually wrote up the steps.

48:20So here's a section on creating and editing multipart polygons...

48:23...creating new donut holes and island polygons. Does this sound familiar?

48:27Set the target layer to the polygon.

48:29Set the task to Create New Feature.

48:31Click the Sketch tool.

48:33Digitize the outer boundary, et cetera.

48:38So this is just a really good way of trying to remember what task you're supposed to perform...

48:44...and the exact steps, 'cause some of them can be pretty complicated.

48:48And we'll go back to Colin for a little bit more demo, a little more slides now.

48:52Yeah, we have one more demo after this so...

48:58All right, so the next topic we're going to look at is coincident features.

49:03So it's pretty common for you to be working with spatial data that shares a common boundary.

49:10Land parcels often share boundaries with each other.

49:14Roads may form the edges of parcels.

49:18Forestry compartments may be formed by rivers...

49:21...or some boundaries on compartments and forestry compartments may be formed by rivers.

49:26So from time to time it's pretty common for us to need to modify and edit things that are common...

49:33...in more than one feature class or across multiple feature class...or within the same feature class for that matter.

49:40So the tools that we have to modify and change common things that are coincident with each other...

49:46...are located primarily on the Topology Editing toolbar.

49:50So the Topology Editing toolbar has many different tools on it, several of them.

49:55It has construction tools for constructing topologies.

49:59It has tools to validate topology.

50:02It has tools to fix errors that are discovered by the topology tools themselves for you.

50:08And then it has some tools for editing coincident geometries.

50:11Now, in order to use all of these tools, you will need an ArcEditor or ArcInfo license level...

50:19...and some of these tools will require you to predefine a set of topology rules and then to validate those rules...

50:27...in order to discover errors and then to fix them with the tools that are there.

50:31But for the simple tasks where you don't necessarily want to have a validation of a series of rules...

50:39...you may want to consider using something we call map cache.

50:43What the map cache is, is we're taking a subset of the tools on the Topology toolbar...

50:48...and we're making them available for you to use without having to go through the entire geodatabase topology.

50:55And the map cache is developed, sorry, map topology is developed using the little Map Topology tool...

51:00...which you'll see is on the toolbar right over here.

51:03Now, depending again on the license level that you're using...

51:07...you may get more or fewer of these tools available with a map topology.

51:13Now map topologies are available with an ArcView license, and you get fewer of the tools.

51:18With your ArcInfo license, you get more of the tools. In fact, you get Planarize as one of them.

51:23So map cache, map topology, when you're working with it, will also work with shapefile features...

51:30...for features out of shapefile and geodatabase.

51:33Whereas a full geodatabase topology will just work with features from a geodatabase.

51:40So here's the scenario.

51:41You're working with some data, you've got some shapefiles, they have forestry compartments...

51:45...you've got a feature class that has some rivers, and the rivers need to be coincident with the boundaries...

51:51...of these forestry compartments, and they're not, and you need to do some work on them.

51:56So what would you do? So you begin by building a map topology.

52:00So you temporarily create, or ask the software to look for coincident features within the extent you're currently working.

52:08So the map topology will go and look to see are these things coincident or not.

52:13And it'll give you the ability with map topology to see who is coincident.

52:18Who's participating in something?

52:20And then you'll get some available tools that'll allow you to select...

52:24...and edit those coincident features and modify them if necessary.

52:28So if we look at some examples, here is an example of a boundary or a line...

52:33...that is being shared by multiple polygons, two parcels in this case.

52:39I built the map topology. I used what is called the Topology Edit tool to select that common boundary.

52:47Now you'll remember that if you use the standard Edit tool in the Editor menu...

52:52...when you select something the color is cyan. Remember?

52:57If you select with the Topology Edit tool, the color of the feature being selected is magenta.

53:03So this cues you visually that you're selecting something that has some kind of coincidence with something else.

53:11So to view the coincident features that are participating right now in that particular possible edit you're doing...

53:18...you can use the Show Shared Features button, and it'll show you which layers the common features...

53:24...are being derived from and which object IDs.

53:27In other words, which identifier of those features you're currently working with.

53:32And you can choose to check off and remove some of the features from being modified at the same time.

53:37Now in the example that we're using above there, we're modifying both parcel lines...

53:42...parcels, and zoning data at the same time.

53:45Three different feature classes that all have some coincidence at that location.

53:51Now to modify the feature, I've selected it with the Topology Edit tool and I've moved it.

53:56I used the same Edit tool to move it and notice how it rubber-banded.

54:01When I've completed the move, it immediately maintained all the connectivity that was needed...

54:07...and it modified all three feature classes at the same time.

54:13So this is an example of using coincident geometry editing tools.

54:19And this is available with an ArcView license, so you have no excuse for not using it.

54:23They're very powerful, very, very useful to use.

54:26Looking at some other things you can do to a selected topology edge.

54:31We call them topology edges and topology nodes, by the way.

54:34So other things you can do is to reshape the edge.

54:37So there's a task under the Task list to Reshape Edge.

54:42And Modify Edge is another of the tasks that you can perform.

54:46Modify Edge is very similar to modifying an existing feature.

54:49You can add vertexes, delete vertexes, and move existing vertexes around...

54:54...but you're moving them around not on a single feature...

54:57...but on all of the features that are being modified in a coincident manner at the same time. That's very, very powerful.

55:06Now some other things you might want to do, and this is a little more advanced when working with a topology edge...

55:11...is to take the topology edge and split it at some locale.

55:16Then to take the portion that you split away and modify it independently of the other portion that remains.

55:24So in this example, we selected an edge, we split the edge. This is a topology edge.

55:30We split it at a locale, took the segment that we had gotten on the left-hand side of the split...

55:36...moved and modified it, and then completed the edit...

55:39...and you'll notice that we have created a slightly different feature.

55:43We've got that kind of step there instead. Now that's a little more advanced.

55:47To add a little more advance to that, we can do this as well.

55:51What if you have a topology edge that you would like to remain anchored at the bottom...

55:57...but you want to disconnect it from the top, move and snap it somewhere else at the top, but the bottom's got to remain anchored?

56:04So in this case, what we would do is, we select the topology edge...

56:09...and we make sure that we get the edge by holding the E key on our keyboard...

56:13...with the Topology Edit tool active to select the edge.

56:17Then we hold the N key on our keyboard down and select the node at the top as well.

56:24So I'm really selecting the topology node, that common point, and the common line, or edge, shared by multiple features.

56:32So the N key and the E key, to select those two.

56:36And then, to disconnect them from their parent, or from the other features, I hold the S key down on my keyboard.

56:44And the S key will change the cursor to a four-arrow cursor as you see in the middle graphic that I'm showing you here.

56:52And once that happens, you know you have now disconnected both the edge and its node...

56:57...and you can move it and snap it somewhere else and then release and complete the edit.

57:02Little more sophisticated, but it's fairly common. You know, you have to move a boundary in one locale...

57:06...after the surveyor's come back and said, It was wrongly put in. So you may need to do that.

57:13So let's switch to a demonstration of some of these things...

57:16...and then we'll finish up after the demonstration with a couple of slides on new stuff in ArcGIS 10...

57:21...and then we'll take some questions after that. All right.

57:25Okay, so in this area I have some parcels that...they're currently one big parcel...

57:31...but we've recently decided that these are going to be able to become...from single family...

57:39...to multifamily from the zoning commission.

57:42So I've added in some of the lines where I'm going to be splitting these big polygons...

57:47...but I still need to add in one more right here.

57:53So to create this line, I've been given an offset value...

57:58...so the line actually needs to start somewhere offset from this point right here.

58:03Well there's not actually a very good way to do that.

58:06As you guys have probably found out, that it's completely acceptable to create a construction line...

58:11...or some kind of temporary feature or temporary segment to get your work done.

58:16So I know that one way I could do this is to create a segment of the length of the offset...

58:22...and then go back and delete that segment later.

58:27So I also know that I'm going to be selecting a lot of features, but I don't want to actually be moving them.

58:32So now's probably a good time to turn on the Sticky Move Tolerance.

58:36So I go to the Editor Options, and we'll just kick up the Sticky Move Tolerance to maybe 10 pixels, and say OK.

58:45So now I click this parcel, and you see I really have to move it.

58:50It's not actually going to move until the feature has been moved greater than 10 pixels.

58:58So let's go ahead and create that first segment and my line to split my parcel.

59:03So I changed my target over to my boundary lines, lot lines subtype...

59:08...we'll snap to the end, and then enter that offset value I was given.

59:14So make the length say, 11 meters, snap to this edge, and then I want to create this other segment perpendicular.

59:28So right now it's snapping using the Perpendicular to Sketch option. You see, right there it is.

59:35And we'll click to create that vertex and then finish the sketch.

59:39So what I want to do is go back and delete this vertex right here.

59:43So I just right-click and say Delete Vertex, and when I finish the sketch...

59:47...I'm left with a feature that's exactly where I wanted it.

59:51So let's use this feature to split this polygon here.

59:54So I'm going to show you a couple of methods to do this, and so depending on your license, one may work better for you.

1:00:02So I've already shown you Cut Polygon Features, so let's use that again to actually split a polygon across.

1:00:08So I'm going to select my polygon, and then go up to Cut Polygon Features.

1:00:14So I could just sit here and trace this line, or snap to this line, and cut through it.

1:00:21But let's say that this line were actually a little more complicated.

1:00:25So I'm going to quickly reshape it just to kind of show my point here.

1:00:32So what if my line looked like this? Or what if it's curved?

1:00:35How can I get this shape into the line I want to use to cut my polygon with?

1:00:41Well, here's the way to do this.

1:00:43So I'm going to snap to the end here, right-click and say Replace Sketch...

1:00:49...and notice how my sketch just kind of sucked up the shape of that line that I created there.

1:00:55So again, that was called Replace Sketch.

1:01:00And now I've finished the sketch, and you see that I have this polygon that's now created using that exact shape.

1:01:07So why didn't I use Trace here?

1:01:09And the answer is because in ArcGIS 9.3, Trace just won't work with cutting polygons.

1:01:17The problem is that Trace requires the line to be selected, but Cut Polygons requires the polygons to be selected...

1:01:25...so the way to get around that in 9.3 is to download a developer sample called Cut Polygons Without Selection...

1:01:31...and it will allow you to use the Cut Polygon Features without requiring it to be selected...

1:01:36...which therefore allows you to use Trace.

1:01:39So in ArcGIS 10 this is fixed by the way...

1:01:41...so you can use Trace without a selection, and so reshaping and tracing all work fine.

1:01:49So let me show you another method now.

1:01:51So if you have an ArcEditor or ArcInfo license, you can use this way.

1:01:56It's on the Topology toolbar, but I do not need to have a topology to use it.

1:02:02So I'm going to set my target layer to my parcels, 'cause that's what I want to split...

1:02:09...and I will select each line that I want to use to make the split.

1:02:18Then I go to the Construct Features command.

1:02:23Construct Features is quite powerful, because it allows you to both create new polygons using selected features...

1:02:30...to create polygons using the existing features...

1:02:33...but it also allows you to split your existing features in the target layer...

1:02:38...which is my parcels, using these selected lines.

1:02:42In ArcGIS 10, we've actually pulled these apart into two separate commands...

1:02:45...so it's much easier for you to figure out what you're supposed to be doing.

1:02:49We have one that creates polygons and another command that splits polygons.

1:02:54So I click OK. And now you see that I end up with a whole bunch of new polygons.

1:03:00So it split each one of these using that line. So now let's go ahead and attribute these features.

1:03:07Remember I said that we've been approved to change these from single family to multifamily residential.

1:03:14So I'll turn off my selection from my other lines and just drag a box and select the whole thing, all my parcels here.

1:03:21I'm going to go to the Attributes window. You see it lists every single feature that I have selected in my Parcels layer.

1:03:31So if I click one of these features here, and I change the zoning from residential to residential multifamily...

1:03:39...it only updates that one feature.

1:03:42But remember, I have all these that I need to change it to.

1:03:45So what I can do is go up to the layer name and it will allow me to change the attributes for every single feature in the layer.

1:03:58So now when I go to all my other features, it's changed them. And by the way, this is called a coded value domain.

1:04:06This is how you get a drop-down in your Attributes window. It's a coded value domain.

1:04:12It's available for ArcView licenses, but you must create a geodatabase to use it. It cannot be used inside of shapefiles.

1:04:22So let's think about what these updates did to my coincident features.

1:04:28I now have a lot of shared features that I didn't have before.

1:04:32So you can either build a map topology if you have ArcView...

1:04:35...or in my case, I actually have a geodatabase topology, because I wanted to set up some rules that say...

1:04:41...my parcels should not overlap each other, my parcels should not have gaps, and those sorts of things.

1:04:48So that's the advantage of a geodatabase topology...

1:04:51...is it's much more stringent in terms of the spatial integrity that it allows you to apply to your data.

1:05:01So I'm going to use the Topology Edit tool.

1:05:03And again you can use this with either a map topology or a geodatabase topology, and if I select an edge...

1:05:09...I can open the Shared Features window and it will show me which features share that particular edge.

1:05:18So you notice I'm sharing the boundary and also the parcels layer.

1:05:22So if I needed to make an update to this feature, or this edge...

1:05:26...I should probably be using the Topology tools instead of the regular editing tools.

1:05:30So let me show you why. Let's say that this line here, this is my road, it needs to be reshaped...

1:05:38...and it's going to be extended to look more like this one over here.

1:05:42So the road will be expanded and it'll go over here...

1:05:45...so I need to change this corner of my parcels once the road gets expanded.

1:05:50So if I go to the Reshape Feature task, Reshape Feature is only going to update one selected feature.

1:06:01So right now you see that I have my parcels selected and it only updates that one.

1:06:06So if I cut off that edge, you see that it left me with that boundary line not being updated.

1:06:13So that's not what I want. I really need to be using the topology editing tools.

1:06:17So if I go back to the Topology Edit tool, select that edge, and I change my task down to Reshape Edge.

1:06:26So you see, that's under Topology tasks compared to being under Modify tasks.

1:06:31And now when I draw that same line, it updated both of those features at the same time.

1:06:38And the same thing would apply if I went to modify the edge. Like let's say I needed to insert a vertex here.

1:06:45It's actually going to be inserted on both of my features.

1:06:52All right. Back to Colin.

1:06:55All right. Our last topic, if you have not already gone to some sessions on ArcGIS 10...

1:07:01...just a few brief things to look out for that are new and improved...

1:07:04...and fun things to start exploring when you do get your hands on ArcGIS 10.

1:07:10Some interesting things. No longer the same options on the Editor toolbar for you to choose the layer, choose a task.

1:07:17No need to do that anymore. When you start editing in the ArcGIS 10 ArcMap environment...

1:07:24...you're immediately going to get what's called a Create Features window.

1:07:28And so all available layers that are editable will appear in the Create Features window for you...

1:07:34...and you'll notice something interesting there, is that they actually follow...

1:07:37...and have the same symbology as they had in the layer.

1:07:40Also, for each of the editable layers it's possible to have it create a features template...

1:07:46...and in the feature template you can predefine symbology and the appropriate editing tools...

1:07:52...that should be used to create or edit those kinds of features.

1:07:56So you can remove tools or disable certain tools that you don't want somebody else to use when creating a parcel.

1:08:04You can leave them with just specific editing tools to create parcels with.

1:08:08So these are things that you need to look for.

1:08:10There are feature templates that are stored with the layer and with the map document for layers that are editable in ArcMap.

1:08:18And then there's a Create Features window to manage all those feature templates as well.

1:08:23Also, the editing environment honors all the layer properties.

1:08:28So in your layers, if you had a definition, so you preselected only 20 features out of a couple of hundred...

1:08:36...and your layer consisted of that selected 20, then the edit tools will honor the selection of those 20...

1:08:43...and only let you edit the 20, not all hundred of them.

1:08:46This is pretty good. So any of the definitions that were there, any of the layer properties that were set...

1:08:51...such as symbology and preselections, and so forth, are honored by the editor.

1:08:57You'll notice the new snapping environment when working with the editor.

1:09:01With editing in ArcGIS 10, snapping is always on, so you don't have to go and create snap agents.

1:09:08You don't have to modify or do anything. It's always there.

1:09:11What's nice is that there's a new little snapping menu that has different varieties of snapping that you can invoke and use.

1:09:19Also, if you do, and you really like the old snapping, there is an option to turn on what is called classic snapping...

1:09:27...so you can get your old snapping back if you wish to. But it's one or the other.

1:09:32So you either have classic snapping or the new variation of snapping, and not both of them.

1:09:37So that's something to be aware of.

1:09:40So snapping is much simpler, and as we said, always enabled...

1:09:44...and works across the board with multiple tools, not just the editing tools.

1:09:48So you have access when working with ArcGIS 10 to a much quicker way of getting to the toolbars.

1:09:54So you'll notice in the graphic below, I'm busy sketching, and as I'm sketching...

1:09:59...a toolbar is there right at the point that I'm sketching...

1:10:02...saying, hey, by the way, these are some of the construction tools you can use while sketching this feature right now.

1:10:08So you'll notice those constraints for parallel and perpendicular that used to be right-clicks...

1:10:14...they're on that little menu there right away for you.

1:10:16So they're appropriate, they're in front of you, they're right there.

1:10:19So the whole workflow is much, much simpler, and much easier to use in ArcGIS 10.

1:10:25So it's much easier for you to edit existing features.

1:10:28What's another area that's really nice is that when you're editing or modifying an existing feature...

1:10:34...there's a new Vertex Editing menu that'll pop up as well, and you can select multiple vertexes to target for a delete.

1:10:42You can insert vertexes very easily and delete a vertex very easily with the Vertex Editing.

1:10:47So select, move, and delete multiple vertexes.

1:10:51The thing Rhonda mentioned about selecting things that are in overlap.

1:10:55Remember, I told you to use the N key to kind of cycle through selected features that are in overlap.

1:11:00Well, there's actually what they call a chip that pops up for you...

1:11:04...when you have multiple...or features that are in overlap that can be selected.

1:11:08The little chip gives you a drop-down menu and says, Which are the features do you want in this locale?

1:11:14So a lot more response and feedback for that.

1:11:17To start editing, you don't have to go to the Editor menu either.

1:11:21You can just right-click on an editable layer and as you would have gone to its properties...

1:11:25...one of the choices in the table of content right-click is Start Editing.

1:11:29So you can invoke or start the editor right there and then if you wish to in the table of content.

1:11:35You have a lot better on-screen display feedback as well.

1:11:39So things like snapping will give you much better feedback.

1:11:42There are enhancements to topology editing and there are several new geoprocessing tools for editing.

1:11:49So you can automate some batch processes through these geoprocessing tools...

1:11:54...so you may want to add them into, for example, a Python script to be used to do some batch processing.

1:12:00So there are several tools there.

1:12:02And there are also some new workflows, a lot of new workflows in fact for editing parcels.

1:12:07And I would recommend, take a look at the help doc.

1:12:09Rhonda's done an awesome job of writing that and creating the tutorials and helping with different workflows and scenarios.

1:12:17And remember, resources.esri.com is a good locale to go to get some additional help.

1:12:24So, there are a few, few more editing related topics around today.

1:12:30Geodatabase Editing Workflows is on at one-thirty, Web Editing with ArcGIS Server at one-thirty...

1:12:36...and Editing Parcels in ArcGIS in room 3 at one-thirty as well.

1:12:41And tomorrow there's a What's New session, which will cover some editing stuff too.

1:12:45Also the island downstairs is open till one-thirty, and at this point there are some Virtual Campus classes...

1:12:51...that you may want to consider and some instructor-led classes.

1:12:55The Data Production and Editing one's a pretty good one...

1:12:57...and then there are two introductory ArcGIS classes, Desktops 2 and 3 that also cover some editing processes.

1:13:04So we're open for some questions.

1:13:07I'm going to relax and Rhonda's going to take the questions. I'm being naughty.

1:13:12Okay.

1:13:13And don't forget the survey forms everybody please.

1:13:16Okay. [Audience question] If snapping's always turned on in ArcGIS 10, will the Spacebar disable it?

1:13:21Okay, the question is, Because snapping is always enabled, can I still disable it using the Spacebar in ArcGIS 10?

1:13:27And the answer is absolutely. You can, when you're sketching, if you just hold down the Spacebar, and you say...

1:13:34...I don't actually want to snap to that, it'll just, no snapping happens at all.

1:13:42Any more questions? Yes, sir?

1:13:43[Audience question] Is ArcGIS 10 going to have the Topology toolbar also?

1:13:49The question is, Does ArcGIS 10 have the Topology toolbar? And the answer is yes.

1:13:52There's not really too many major changes to the way topology works in ArcGIS 10.

1:13:58The big things were just little enhancements.

1:14:02For example, we did add six new geodatabase topology rules that'll be pretty useful for you guys.

1:14:08And then the other thing is, when you're actually editing topologies, you may have seen these demos...

1:14:14...where you're using the Edit tool, and then you can select multiple vertices and drag vertices and delete vertices...

1:14:23...and that sort of thing, so all that's also available inside the Topology Editing tool as well.

1:14:32If you have suggestions, by the way, come down to the island...

1:14:34...and talk to the developers about suggestions for the topology tools if you like for future.

1:14:39Yeah, we're actually looking into that area, what we can do to enhance it and for some future release to make it easier. Okay.

1:14:49[Inaudible audience question]

1:14:52Is there a way to clear the snapping environment?

1:14:54[Inaudible audience question]

1:14:56Okay, the question is, How do I uncheck multiple layers in the Snapping Environment window?

1:15:03And unfortunately the answer is, it's not very easy.

1:15:07This came up yesterday I think.

1:15:10Someone asked us that on the island and we were sure holding down the Ctrl key would work.

1:15:15 [Audience comment] They actually said that in one of the classes, but I...

1:15:17Yeah, it's probably the EGUG or something like that, and we tried it out and we couldn't believe it didn't work...

1:15:25...so we think that was a bug, that it may have worked before...

1:15:27...and doesn't work now or something like that. So we'll look at that.

1:15:31This gentleman had a question. [Inaudible audience comment]

1:15:34Oh, okay. So any other questions? No? Alright, thank you very much for attending, everyone.

1:15:42Great. Have a great rest of the conference and enjoy the party tonight.
