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.

You can also select or deselect toolbars from the Customize menu. The following notes will provide links to atcscene that will provide necessary details about how to add your data, adjust the display properties and to navigate your model in 3D.
The image will also include the outline of the frame. Name your new shape file something like frame.

Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and uncheck the option for Gamma Stretch. It is convenient to plan our model with a rectangular boundary. You can quickly learn the name and more about its capabilities.
Add your clipped DEM and your buildings and your groundplan.
Introducing the ArcScene user interface
Make sure that the Clamped to Ground option is unchecked. In aarcscene earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation of the terrain. Save your buildings as a shapefile in your data folder. Se the refeences below for hints on navigating in your ArcScene model. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar.
Then we make a copy of this layer and change the symbol to a sphere that has its base height set as a constant value of As we have explained above, one element of our site model will be an image of the groundplan for our site and its context. To demonstrate this capabilitty we will create a point and use a combination of 3D symbols to transform the point inot a arxscene of a 30 foor tall sign to call attention to the transit stop next to the railroad tracks.
You can use the Advanced symbol swettings to read the height for each symbol from an attribute.
We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. If you export an image from arcmap with the Georeference option checked. Export ardscene Frame polygon with the Clamped to Ground option checked. Adjust the Base Height property of your point so that it shows up on the surface.
Rather than usng a sensible default display properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack. For the context image, you don’t necessarily need a very high-resolution image. To list data by source will display the storage path above the layers.

Because your model is not perfect qrcscene may want to viosit the site and take a photograph and then change the view settings in ArcMap to recreate the optics of your photo as shown in the example below. This wil make it very easy to register the image as with other layers as we export them to other tools.
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 we move them into various tools that do not support georeferencing. Export your Clipped Buildings layer. Dockable windows collapse from the 3D view when not in use.
There is no 3D globe surface provided in ArcScene.
We don’t want the images to have more resolution than we need, because this will create unnecessary problems in every thing we do subseqently. Thererfore, it is better to choose a new name for your exported image iof you have to export more than once. We will look at a few additional types of data that let us represent the form of places in three dimensions, or at tutorixl two-and-a-half dimensions! 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.
Export a Groundplan Image Zoom out to your context frame and measure its width in meters.

Then we have everything we need to make a nice compact 3d model of our site! When saving, be sure to set Save Files of Type to Shapefile. This will change as you use different navigation tools to move around arcscens data and 3D environment.
