00:01At 10.2 also, we dramatically improved the 3D visualization.

00:07The content generation capabilities from CityEngine have now been integrated into the desktop so rule-driven content can be easy.

00:16We can make 3D virtual cities with 3D models simply.

00:21And also there's a new capability that desktop users can do, which is to publish things called web scenes.

00:27Web scenes are kind of like web maps; you can send them out, ship them to anyone and share the content of your city on the web...

00:36...and people can use it without any software.

00:38And then finally, lidar processing gets much faster.

00:42But, well, hey, Craig, you want to show this?

00:46Yes. Better than talking about it.

00:48Alright. Thank you. Good morning.

00:51My name is Craig McCabe and I'm from the 3D cities team, and I'm excited to show you...

00:55...some of the new desktop tools for 3D cities in 10.2.

01:003D content's compelling, and there's more demand for it every year, which creates a challenge.

01:05How do I make my city 3D?

01:09Most cities view their essential data in a view like this on the desktop.

01:14What they'd really like is a beautiful 3D view of their city in a web browser that leverages their existing data.

01:23In the past, creating a 3D cityscape was an expensive and manual process.

01:28As your city grows and changes, these hand-built models are quickly out-of-date.

01:34With ArcGIS for 3D Cities, we can rapidly accelerate this process.

01:38Let me show you how to go from 2D data to a shareable 3D city in three steps.

01:44Step 1 is importing your data into the data model.

01:48We've included schema generation tools for creating a localized geodatabase, and importing, or ETL tools...

01:54...for bringing in city GML, Local Government Information Model, or custom schemas.

02:00You just map your attributes to those in the 3D cities data model.

02:04Step 2 is converting your 2D building footprints into 3D textured facades.

02:11Brand-new in 10.2 is the ability to apply CityEngine 3D modeling rules directly in ArcGIS.

02:19Just point to your building footprints, your preconfigured building facade rule package...

02:25...and specify your output multipatch feature.

02:27We'll call it Building Shells.

02:30Now what the tool does is it reads the attributes of your building footprints, extrudes it according to the total height...

02:37...splits it into the levels aboveground, the number of floors, and then applies a texture according to the use type...

02:42...in this case, an office building.

02:45And we can use the same procedural 3D modeling approach for other city data, our street network, our trees...

02:51...our park, and our river.

02:54And that brings us to step 3.

02:56Now we just open up our ArcScene document and turn our rule-generated features; our textured multipatches...

03:03...our streets, trees, and park.

03:06And then we add our river and our textured basemap.

03:10And that's it; three steps to a 3D city.

03:20And now we can dress it up a little bit.

03:22Maybe bring in COLLADA files of our bridges or other operational data we want to share.

03:28But 3D GIS isn't just about seeing in 3D; it's about understanding.

03:32A good example of that is zoning regulations.

03:35We have a table of regulations for the city of Portland with floor/area ratios, maximum building heights...

03:41...setbacks, and other information.

03:43For the average person, this is a little hard to understand.

03:47So we provide tools to convert these tabular regulations into easy-to-understand, buildable volumes at the parcel level.

03:56So now we just created 3D representations of our tabular information.

04:01And because they're GIS features, we can access the attributes, change our building heights, or setbacks...

04:07...and create new 3D models.

04:11So now we have our 3D city and we want to share it.

04:15Also new in 10.2 is the ability to export to a shareable, 3D web scene, directly from ArcScene.

04:22So let's head back now to our web scene of Portland.

04:27Now I've uploaded this to my ArcGIS Online account, and I've shared it with everybody.

04:30You don't need any special software access, just a web browser.

04:34And because it's built using my GIS data, all the original attributes are maintained and searchable within the scene.

04:40These aren't just dumb models.

04:43And not only can we can share it with everybody, we can also get feedback using a 3D commenting system.

04:49Whether it's about a city maintenance issue or a proposed building that's going up downtown.

04:56In this case, we have a comment about a shadow impact of a new building.

04:59So let's go to comparison mode and compare these existing buildings and proposed buildings side by side.

05:08So now, if we turn on our shadows and move in on the park here, we could see that in the late afternoon in the summer...

05:17...we have significant new shadow impact on a proposed building on the left from about four-forty to five-forty p.m.

05:25This is a significant comment because many cities have regulations limiting shadow impacts on public spaces like parks.

05:32This is a new and really powerful way to communicate with GIS, sharing your 3D city on ArcGIS Online.

05:39And with 10.2, we've made it even easier to get started. Thank you.

05:51Now I'd like to introduce my colleague, Nathan Shephard, so we can show you the future of 3D on the web.

05:56Thank you, Craig. 3D cities are awesome.

06:01So, my name's Nathan Shephard.

06:03I'm up here because I have a funny accent, and I work on 3D stuff in Redlands.

06:08So the web scenes that Craig showed are perfect for sharing an area of interest in a browser with no plug-ins and no installs.

06:17However, for large quantities of data, it's my pleasure to show you the next generation of web scenes...

06:22...currently being developed in our Zurich office.

06:27This web scene is service based; it's connected to streaming services.

06:31Again, don't forget, no plug-ins and no installs.

06:35So, as we fly down into Philadelphia, more content, [unintelligible] pictometry in [unintelligible]...

06:42...simply streams down into my browser and we can have web scenes of any size.

06:55Web scenes can also make service-based requests, like to a geocoding service.

07:00And from the result, you can see that we have 3D labels...

07:03...and we can start labeling interesting or key features inside our scene, like streets.

07:10This means you'll never be lost in downtown Philly. We don't want that.

07:18And because we can zoom back out to the global scale, I can start adding in other interesting cartographic 3D services...

07:24...such as the path and wind speed of Hurricane Andrew.

07:28And don't worry, existing services are also supported; so we can just switch our basemap...

07:33...literally, just changing one of those service layers, and we can see which cities and which international flights...

07:43...might have been impacted by this hurricane.

07:46Oh, and all of these services are also supported on the 3D runtime.

07:49So you can see the exact same content on your iPad.

08:02Thanks, Craig.

08:04So, web scenes are a great way to communicate, and with this next release...

08:08...they'll be connected directly to your services and look a little bit like this.

08:13I hope you've enjoyed this glimpse of the future of 3D on the web.

08:16Once you get here, it's hard to leave. Thank you.

08:24Good. Thank you.

08:27Thank you.

08:29Do you believe in 3D?

08:30A little bit.

08:31Why?

08:33Too many reasons to count.

08:34Yeah. Well, that's good.

08:36Yeah, I think 3D is a major footprint for us.

08:41Well, I told you in this movie that we're going to show over the last 30 years of all of your work...

08:46...it went from black and white to color, and there was no going back.

08:50Color was the new standard.

08:53Exactly. So, is this what you're after?

08:55That's what I'm after. Come join us on 3D, it's good.

08:57Okay, good. Thanks.

08:58Thanks, Jack.

08:59Thanks you, guys. Yeah.
