00:01It gives me great pleasure to introduce Lauren Rosenshein.

00:04And Lauren is a geographer, a quantitative geographer.

00:09She's just recently got her master's degree and is working in the world of spatial analysis/spatial statistics.

00:17The demo that she's going to give is not exactly relevant to geodesign, but it's totally relevant to geodesign.

00:25She's going to talk about sharing tradecraft, sharing what one person creates and allowing other people to use it...

00:33...and then resharing it, et cetera.

00:35So, Lauren.

00:37Thanks, Jack.

00:40So I'm a crime analyst in San Francisco, and I've got data on all the points that represent crimes for the last year in my area...

00:50...and my boss has asked me to do a hot spot analysis.

00:54Unfortunately, I have no idea how to do a hot spot analysis.

00:58So, what I want to do is rely on the community.

01:01I know that there are a lot of analysts out there, crime analysts, who specialize in this sort of thing...

01:06...spatial statistics/geographic analysis, and I know that they're out there sharing their methodologies, their tradecraft...

01:13...so as an analyst, I want to go and take advantage of all the work that they're doing.

01:17So what I'm going to do is I'm going to go out to ArcGIS.com, and I'm going to search for crime analysis.

01:26And one of the things that pops up here is a group.

01:28I was searching specifically for groups, and it's a crime analysis collaboration group.

01:32So I'm going to dig in here and I see some things that people are sharing.

01:35I'm seeing data templates.

01:37I'm seeing web applications.

01:39And I also see this DC crime hot spot analysis workflow.

01:44So when I dig a little bit deeper into this workflow...

01:46...what I see is that the DC crime analysis unit has shared a geoprocessing package.

01:53That package is going to walk me through the workflow and it also provides the data necessary...

01:58...for me to analyze patterns and find hot spots of violent crime in Washington, D.C.

02:03So while I'm not interested in hot spots in Washington, D.C....

02:07...it's definitely going to get me on the right track to doing this same analysis in San Francisco.

02:12So what I've done is I've downloaded that geoprocessing package, and I already have it on my machine.

02:18And all I'm going to do is drag and drop that geoprocessing package right into ArcMap.

02:23So, two things happened when I dropped that into ArcMap.

02:27The first thing I noticed is that some data was added to my table of contents.

02:31And the second thing I noticed is that a new tasks node here was added to my Analysis window...

02:36...and that task is the crime hot spots task that I just added in and that includes the tool itself which I can run.

02:44It also includes some associated files.

02:52So if I zoom to that layer, I can see what...really what this geoprocessing was all about.

02:58I see those crime points that those analysts used to do their hot spot analysis...

03:03...and I also see the hot spot surface that they created, and I know this is exactly what my boss is looking for.

03:10This is what the decision makers want to see as far as what a hot spot analysis is.

03:14So, what I want to do is use this same methodology on my own data.

03:20So I'm going to go back to San Francisco, and before I dig in and try to run the analysis, I first have to learn about it.

03:28And one of the things that the geoprocessing package allows me to do...

03:32...is create and associate some files with that geoprocessing package.

03:37So one of the things that the crime analysts in DC did was they incorporated a PDF...

03:42...and that walks me through what this hot spot analysis workflow is all about.

03:47So if we look through there, we can get a better idea of what the model is, and we can see piece by piece what it does.

03:53So it starts by selecting some of those crime incidents...

03:56...both by a location so I can choose just to look at a particular area of my data...

04:01...and also by the time of day which is interesting.

04:03I know that analysts often want to see just nighttime crime or just morning crime.

04:08I also see that that's done interactively...

04:10...and what that's going to help me understand when I start to run my analysis what that part of the tool is all about.

04:17It then runs a hot spot analysis, tells me about some of the parameters that were chosen...

04:23...so that I can trust the parameters that they chose because they're explaining their methodology here...

04:28...and then ultimately creates that hot spot surface.

04:31So now that I understand a little bit more about it, what I want to do is dig in here and run that analysis.

04:38So all I have to do to run the analysis is double-click on that task, and instead of using that DC crime data...

04:44...I want to point to my own San Francisco crime data.

04:48Now I can interactively choose the location and the time of day.

04:51So by choosing this nighttime option here, when I draw this polygon on my map...

04:57...I'm not only just looking at crimes in the northeast quadrant of San Francisco...

05:01...I'm also only looking at the nighttime crimes that occurred in that northeast quadrant.

05:05So I can get really specific about the analysis that I'm doing.

05:09And then I just run my analysis.

05:12And with really very simply, without having to learn a whole lot about hot spot analysis, I can run it...

05:18...and I know that I can trust those parameters that were set because the DC crime analysts explained their methodology.

05:24I can feel confident about those results.

05:26So when I take a look back here, I'll turn those points off...

05:35So that's really great.

05:36But I have some ideas for how I want to improve this model.

05:39So, another really important aspect of a geoprocessing package is this isn't a static service.

05:45I'm not running this from the web.

05:47I'm a professional GIS analyst.

05:48I want to dig in there and change it around so that it meets my needs.

05:53So what I can do is right-click and edit this, and it's going to bring me right to the full model.

05:57I can go in here.

05:58This isn't a picture, it's in ModelBuilder.

06:00I can go in, change the parameters that I want to.

06:03One of the things that I want to do is not only allow analysts to choose by location and time of day...

06:08...I also want to give them an option to do a date extent.

06:11So in this case, we were looking at only November crimes.

06:14But I know analysts often want to look at the spring, summer, fall, and look at differences in that sort of way.

06:19So I want to allow users to have that sort of ability to query the data.

06:24So what I'm going to do is go in here and create a variable, type string, and go in here and set a default date for November 1st.

06:35And rather than going through and adding another variable and ultimately editing a SQL query...

06:41I've already gone ahead and improved that model for my own analysis.

06:46I'll just show you what it looks like here, and you can see the small changes that I made.

06:49I made the SQL query not only look at time of day but also that start date and end date.

06:55And now I can just go ahead and run that analysis.

06:59It's going to look really similar to the one that DC provided.

07:02Now I can also set the start date and end date.

07:05In this case, let's look at October through November and maybe we're interested in morning instead of nighttime crimes.

07:13So just go ahead and I run it, and I've made those small improvements...

07:17...that really make this fit what my decision makers in San Francisco are looking for.

07:23So we can see if I turn off the original one that now this new hot spot map has been created using my changes.

07:30So now that I have a model that's working.

07:32It ran successfully.

07:34I feel confident that's going to work when I share it with somebody else.

07:37I can go in here to that result, right-click on it, and have some options for sharing it.

07:42So I can share it as a geoprocessing package, or I can share it as a geoprocessing service.

07:47So to start with, we'll look at that geoprocessing package really quickly.

07:50And all I have to do to share this as a geoprocessing package is choose a location to save it.

07:55Let's call it Date Extent Geodesign, and then I have an option to include some attachments.

08:05So it's really important to remember how vital that PDF, that attachment, that methodology was to this geoprocessing package.

08:11It was really the meat of the geoprocessing package to me in terms of learning more about this analysis.

08:19So I've gone ahead and I've made some changes to update it for the changes that I've made.

08:23I've created a new PDF.

08:25Then I have some options for if I want to change the names of my inputs and my outputs...

08:28...that sort of thing so that ultimately it fits what an end user would expect.

08:33And then I just go ahead and share it.

08:35So when I share it, what it's going to do is it's going to take all my input data.

08:38It's going to take my output data.

08:39It takes that PDF and my model including any embedded models.

08:45If I had models inside of models inside of models, it would grab all of that and put it into this geoprocessing package.

08:51And from that package, I can send it in e-mail, put it on a shared folder, and obviously put it back up onto a group on ArcGIS.com.

09:00So similar to the way that I can share a geoprocessing package in that same dialog that we saw which is new in 10.1...

09:07...I can also share that same geoprocessing package, that same geoprocessing model, as a geoprocessing service.

09:14And I can do that really easily right from the Results window with a really easy dialog.

09:19And the reason that I would really want to do that is because I want to give...

09:24...I want to empower decision makers to use my professional knowledge, my professional GIS capabilities...

09:32...so that I don't have someone coming into my office every single day saying...

09:35...okay, I'm interested in the spring, well what about the nighttime, what about the morning, I just want April.

09:39I want to enable them to do that sort of analysis.

09:43So what I've done is by creating this geoprocessing service, I can enable them to do that on a simple web application.

09:48So here, I'm giving decision makers, not only the ability to look at the points on a map...

09:53...because sometimes points on a map are very interesting.

09:56They can query by the time of day.

09:58We can look at evening or nighttime, any sort of date extent we're interested in.

10:04But ultimately what I want to enable them to do is do that complex spatial analysis without having to understand it...

10:10...and I can feel confident that they're doing it right because I set it up.

10:13So they can learn a little bit more about it, or they can just go ahead and run the analysis.

10:18So behind the scenes, that geoprocessing service is doing all that complex spatial analysis and returning to them these hot spots.

10:25And because I've enabled a geoprocessing service, and this is now in this world of web services...

10:31...I also empowered them to take advantage of all these other services that are provided by Esri and other GIS professionals...

10:38...and dig in.

10:39So here, for instance, I wanted to give the decision makers the ability to dig a little bit deeper, and from each of those hot spots...

10:45...we're now using Business Analyst Online to get a better understanding of some of maybe the underlying related factors.

10:51In this case, we're looking at one of those high-violence hot spots...

10:55...and we see that the average household income is much lower there than the county and the state.

11:00We can see unemployment is actually higher, and we can see high school dropout rates higher.

11:05Similarly, we can go to one of these low-violence areas, and we can see that the average household income is much higher.

11:17We can see that unemployment is low, and we can see that the high school dropout rate is low.

11:22So a really simple web application that any decision maker could use...

11:25...but we're empowering them to do some really complex spatial analysis behind the scenes that we feel confident in...

11:30...because we've ultimately authored it the right way.

11:35Thank you, Lauren.

11:36Great.

11:42Why I wanted you to see this is not because you're so interested in crime, or maybe some of you are...

11:54Maybe it would have been the data.

11:55Maybe it would have been the way that they represented the data as a map.

11:59In this case, it was a model.

12:01And I think as we progress on, not only will we invent and develop methods and tools and processes...

12:09...but also where we can really get the bang is to share those...upload them, other people discover them, download them...

12:16...a water resource model, a location-allocation model, whatever it is.

12:22As we invent both the suitability directed process models or the evaluation models...

12:29...what I wanted you to do is just get a quick sense of this is going be fun, isn't it?

12:34Leveraging each other.

12:35GIS has always been about sharing data.

12:38That's good.

12:40Share data, overlay data.

12:41But how about the data models, how about the analytic models, how about the cartography...

12:47...how about the methods, how about the workflows - all of that's going to come online.

12:51So, again, thank you, Lauren.
