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.

This image will represent the roads, water, land and open spaces within the area covered by our clipping frame.
Add your clipped DEM and your buildings and your groundplan. This tutoriial problematic, since the Elevation units are in Meters. Later we arccsene investigate how we can create and preserve view corridors after existing buildings are removed in anticipation of developing a new transit-oriented development. The image will also include the outline of the frame. And images are always rectangular. And then change your extent or change your export resolution, the second image will have its georeferencing messed up.
You can also select or deselect toolbars from the Customize menu.

Dockable windows collapse from the 3D view when not in use. In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios. Later, you may add new subfolders to hold the resources that are used and created by other applications.
The table of contents has several ways of listing layers: So if your context image is more than 4 kilometers wide, think about that. Go to the symbology properties tab for your point shapefile and investigate the multitude of 3D symbols that you can find in the Style References. Export your Frame polygon with the Clamped to Ground option checked.
Thererfore, it is better to choose a new name for your exported image iof you have to export more than once. Export your Clipped Buildings layer. This wil make it very easy to register the image as with other layers as we export them to other tools. Click a tab to expand.
There is no 3D globe surface provided arvscene ArcScene. Available with 3D Analyst license.
Note that if you het a cryptic error message when you try to do this it is probably because you need to change the File Type from geodatabas feature class to Shapefile. For the context image, you don’t necessarily need a very high-resolution image.
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. It may be helpful to make the sky blue. The example also shows how a we can selectively remove buildings form our builsings layer. KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models.
This tutorial will take this a step further. Wil lan object theat we create be visible from key places around a site? Shift-click to select more than obne building. Then we make a copy of this layer and change the symbol to a sphere that has its base height set as a arcscnee value of Fix it Symbology properties of your groundplan, setting Stretch to none as discussed above.

Make sure that the Clamped to Ground option is unchecked. Note that arcscene offers a special box for adjusting the resolution of your exported image in the View Arcsceme box at the bottom left corner of the export image dialog. Use this image as a beginning guide to familiarize yourself with the ArcScene environment.
Note that dockable window controls can be moved around the display to customize your view. Because your model is not perfect you 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.
From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. Then we can navigate to different places in the model check whether the sign is visible. Our arccene 3d model can be useful for investigating how places interact visually. Save your buildings as a shapefile in your data folder. Because we want to make a nice compact 3d model, we will export a clip of the elevation model using the same extent that we used to export the groundplan image.
Save your clipped elevation model as a tiff or an Imagine Image format. You can quickly learn the name and more about its capabilities. 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 arcsxene.

When asked whether you want to build Pyramid Layerssay yes. You should now be able to add your groundplan image to ArcMap. Before we get into exporting the images we should think about resolution. When saving, be sure to set Save Files of Type to Shapefile. You can use the Advanced symbol swettings to read the height for each symbol from an attribute. Finally, we will select and save the buildings that occur within our model study area. For Location choose your data folder.
Name your new shape file something like frame. From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features. A good resolution for your context image may be about a half-meter per pixel, which is good enough to see distinguish buildings, roads, cars, etc.
Think about the sort arcscenr grapnhical hierarchy thou would want in titorial reference image that will be draped on an aerial photo in your model.
