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.

There is no 3D globe surface provided in ArcScene. The image will also include the outline of the frame. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar. Name your new shape file something like frame. It is convenient to plan our model with a rectangular boundary.

The example also shows how a we can selectively remove buildings form our builsings layer. In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios. 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.
Adjust the Base Height property of your point so that it shows up on the surface. These tools optimize interacting with the 3D view and your data.
ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D. Our clipped dataset is going to include: We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground.
From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer.

And then change your extent or change your export resolution, the second image will have its georeferencing messed up. In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image. We are beginning a new project that is going to include a new GIS dataset.
You can quickly learn the name and more about its capabilities. Use the Add Data button to add your new point shapefile to ArcScene. Access more toolbars to add to your view by right-clicking this gray area. Rather than usng a sensible default display agcscene for images of this kind, ArcMap insists on stretching the color ranges all out of whack. As we have explained above, tjtorial element of our site model will be an image of the groundplan for our site and its context.

This is problematic, since the Elevation units are in Meters. How will the removal or addition of buildings create or block views? Later, you may add new subfolders to hold the resources that are used and created by other applications. Available with 3D Analyst license. Save your buildings as a shapefile in your data folder.
You can also select or deselect toolbars from the Customize menu. Save your clipped elevation model as a tiff or an Imagine Image format. 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.
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.
Thinking about it another way, many arcsene like AutoCAD and Sketchup will choke if you try to drape a texture with more arrcscene, say x pixels For some reason, ArcMap 10 and We use this tool to export the buildings and the frame from your scene.
Introducing the ArcScene user interface
Our rough 3d model can be useful for investigating how places interact visually. You can use the Advanced symbol swettings to read the height for each symbol from an attribute. Your clipped groundplan image can be imported directly into Google Earth and registered precisely using your model frame. tutorrial
This tutorial will take this a step further. Like above, there are a few ways of doing this. Export your Frame polygon with the Clamped to Ground option checked.
Note that arcscene offers a tutprial box for adjusting the resolution of your exported image in the View Arczcene box at the bottom left corner of the export image dialog. From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features. Inspect the model to see if it makes sense. For Location choose your data folder.
Export your Clipped Buildings layer. Export your Buildings to a New Shape File If necessary, return to the bookmark you saved for your model frame. You will find this raster in the USGS group layer. At the end of the tutorial we create a 3D model from these that we can play with and tuotrial renderings from a tool called ArcScene.
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! And images are always rectangular.
