The standard editing environment is now available inside both ArcGlobe and ArcScene, allowing for the creation and maintenance of z-aware GIS features. You are able to:
- start editing, stop editing, save edits, use Undo and Redo functions, and do other standard edit management tasks in 3D. The classic Snapping environment is also supported as are precision-creation options such as parallel, perpendicular, deflection, absolute XYZ.
- create and delete individual features. This includes the creation and storage of vertical lines in the geodatabase.
- move, rotate, scale and replace feature geometry (higher level geometry edits to features). This includes the ability to place 3D models (e.g.: COLLADA files) directly into the 3D view as new multipatch features, and then move/scale/rotate them on the landscape.
There are also additional tools for creating and maintaining Terrain datasets (particularly when working with LIDAR data sources) and editing TIN datasets (TIN editing toolbar in ArcMap).
Benefits of editing in 3D
Editing in 3D allows a city planner to drop in a new building, position it to exactly the correct location and instantly see the impact on the city environment.
Geoscientist can interactively edit stratigraphic layers to get rid data anomalies and add local knowledge such as fault lines to the model.
Facilities managers can create and maintain 3D transportation networks directly in 3D.
Civil engineers can effectively manage billions of LIDAR points as multipoints and create a scalable terrain (using the terrain dataset). Also new profile tools and the ability to edit TINs allow for greater quality control of surfaces.

3D Analyst 10 makes ArcGIS a complete system for 3D GIS.
That is a big statement so let me explain. Not only can you view your geospatial data in 3D Analyst, at 10 you can edit your data in 3D and analyze your data in 3D. Now that is pretty huge. Most companies focus on 3D visualization of geospatial data and some are very good at it. However you can only look at your data on a globe for so long. After awhile, the WOW factor starts wearing off and you’ll want to edit and analyze your data in 3D. This is what makes 3D Analyst different from 3D viewers.
So what does that mean: Edit in 3D and 3D Analysis?
We have enabled the standard ArcGIS editing environment inside both ArcGlobe and ArcScene. You can create and delete individual features, move, rotate, scale and replace feature geometry. This includes the ability to place 3D models (e.g.: COLLADA files) directly into the 3D view as new multipatch features, and then move / scale / rotate them on the landscape. All the standard editing options – Undo, Redo, Edit Templates, etc – are supported, as is the classic Snapping environment.
We’ve also made huge improvements in the analysis of 3D vector features. We have added 3D boolean operators such as Intersect 3D, Union 3D and Inside 3D to be used with closed multipatches, new GP tools that expose 3D vector analysis specifically for virtual city workflows, such as Skyline and Skyline Barrier and enhanced existing GP tools to work better with 3D – ‘Select by Location’ dialog uses 3D distances, multipatch objects can participate in the Line of Sight tool.
Note: please download the .WMV file for optimal video quality.
So what does this all mean?
It means that 3DAnalyst 10 is a big leap forward for the handling of 3D GIS data. Not only can you view huge volumes of your data in 3D, you can edit your data in 3D, analyze it in 3D and easily share it with your colleagues or the public.
That sounds great but what can you actually do with it?
I’ll get into that in more detail next time.

So the Lakers beat the Nuggets to advance to the finals, and we decided to take a look at both sports venues in 3D to show how you can use Sketchup to add 3D buildings to your maps.
First we went to the Google 3D Sketchup Warehouse where we can find lots of Sketchup models, many published as KML/Z files which can be used directly in Explorer. Sketchup models have long been supported in ArcGIS Desktop in ArcGlobe, part of the 3D Analyst extension. Google acquired the company on March 14, 2006.
We went to the NBA Arenas collection at the 3D Warehouse
and located the Staples Center and Pepsi Center models, home of the Los Angeles Lakers and Denver Nuggets respectively. Note that there’s a link to “View in Google Earth” (highlighted in yellow below with a red arrow) but obviously we can view these in Explorer too.
If you’ve let the file association for KML and KMZ be registered to ArcGIS Explorer all you have to do is click the link and the KML/Z will open in Explorer. If the KML/Z file association is registered to Google Earth instead of Explorer you’ll see the following dialog when Explorer first starts which lets you choose which application should open the files.
A similar dialog will display from Google Earth if you’ve set the KML and KMZ file association to Explorer.
You can also right-click the link and save the KML/Z file locally using Save Target As…
And then choose File > Open and click KML to browse for the file.
Here’s the Pepsi Center in Explorer:
And here’s the Staples Center. Note that the model author has added additional information about the arena which can be viewed by clicking the model.
