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.

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. The table of contents has several ways of listing layers: This wil make it very easy to register the image as with other layers as we export them to other tools. To list data by source will display the storage path above the layers. 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.
KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models. You should now be able to add your groundplan image to ArcMap. 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.

From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. The example also shows how a we can selectively remove buildings form our builsings layer.
Then we can navigate to different places in the model check whether the sign is visible. Adjust the properties of your new building to set their base heights and extrusion. Now that you know how to create new geometry and navigate to diffeent places you are ready to investigate visibility. 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.
With this in mind, we should create a new folder system that will hold all of this work. Click a tab to expand. 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.
Se the refeences below for hints on navigating in your ArcScene model. Like above, there are a few ways of doing this.
From tuforial pulldown menu on the Draw toolbar, choose Convert Graphics to Features. And then change your extent or change your export resolution, the second image will have its georeferencing messed up.
Dockable windows collapse from the 3D view when not in use. 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.
And images are always rectangular. Our clipped dataset is going to include: ToolTips are revealed when you hover over a tool on a toolbar. In an earlier tutorial on Digital Elevation Modelswe tutoroal some experience with GIS data sources that represent the elevation of arcscsne terrain. 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.
Wil lan object theat we create be visible from key places around a site? If you export an image from arcmap with the Georeference option checked. This will change as you use different navigation tools to move around your data and 3D environment.
As we have explained above, one element of our site model will be an image of the groundplan for our site and its context. ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D.
Add your clipped DEM and your buildings and your groundplan. The image will also include the outline of the frame. For the context image, you don’t necessarily need a very high-resolution image. In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image.

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. We use this tool to export the buildings and the frame from your scene. 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 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 is convenient to plan our model with a rectangular boundary.

Shift-click to select more than obne tktorial. This image will represent the roads, water, land and open spaces within the area covered by our clipping frame.
Save your buildings as a shapefile in your data folder.
