3D data can be displayed and navigated using the ArcScene Application. in this case we will add an aerial photograph (e.g. aerial 5 in the tutorial data folder) . About This Tutorial. This article describes the steps required to load and display topographic, geologic, and cultural data in ArcScene and presents several. This tutorial is an introduction to ArcGIS 3D Analyst, an extension for ArcGIS. The extension needs to 1 From the 3D Analyst toolbar click the ArcScene button.

Introducing the ArcScene user interface
If you export an image from arcmap with the Georeference option checked. I recommend that you have an outer folder named for your site, and a sub-folder within this to hold your GIS data.
Note that dockable window controls can be moved around the display to customize your view. The example also shows how a we can selectively remove buildings form our builsings arcscne. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar.
Your Groundplan image can be added to Google Earth as am Image Overlay note that your frame polygon will make it very easy to register this overlay. For some reason, ArcMap 10 and Later we will investigate how we can create and preserve view corridors after existing buildings are removed in anticipation of developing a new transit-oriented development.
There is no 3D globe surface provided in ArcScene. We are beginning a new project that is going to include a new GIS dataset. Think about the sort of grapnhical hierarchy thou would want in a reference image that will be draped on an aerial photo in your model. With this in mind, we should create a new folder system that will hold all of this work.
When saving, be sure to set Save Files of Type to Shapefile. This wil make it very easy to register the image as with other layers as we export them to other tools.
Name this layer Removed Buildings Turn off your Groundplan so that you can see the building shapes. You can use the Advanced symbol swettings to read tutrial height for each symbol from an attribute. It may be helpful to make the sky blue. Click a tab to expand. Wil lan object theat we create be visible from key places around a zrcscene

Access more toolbars to add to your view by right-clicking this gray area. Note that you can adjust the size and rotation of symbols. In an earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation of the terrain.
We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. Inspect the model to see if it makes sense. You may want to use other overlays with transparency to colorize the photograph or to include details for some other GIS layer that you have.
KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models.

Make sure that the Clamped to Ground option is unchecked. Go to the symbology properties tab for your point tytorial and investigate the multitude of 3D symbols that you can find in the Style References.
Our T sign is created by making a copy of our point layer. Save your clipped elevation model as a tiff or an Imagine Image format. Like above, there are a few ways of doing this. To demonstrate this capabilitty we will create a point and use a combination of 3D symbols to transform the point inot a representation of a 30 foor tall sign to call attention to the transit stop next to the railroad tracks.
Thinking about it another way, many programs like AutoCAD and Sketchup will choke if you try to drape a texture with more than, say x pixels ToolTips are revealed when you hover over a tool on a toolbar. Your clipped groundplan image can be imported directly into Google Earth and registered precisely using your model frame. The main reason for the rectangle premise is that the ground plan of the model is going to be exchanged as an image.

We will look at a few additional types of data that let us represent the form of places in three dimensions, or at least two-and-a-half dimensions! Available with 3D Analyst license.
By the time we get around to exchanfing the model between a number of tools, you will appreciate the utility of having a retangular model with a vector clipping frame that can be used to register the various parts of the model as turorial move them into various tools that do not support georeferencing.
At the end of the tutorial we create a 3D model from these that we can play with and generate renderings from a tool called ArcScene.
