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.

Se the refeences below for hints on navigating in your ArcScene model. 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. Before we get into exporting the images we should think about resolution. This image will represent the roads, water, land and open spaces within the area covered by our clipping frame.

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. You can quickly learn the name and more about its capabilities.

Introducing the ArcScene user interface—Help | ArcGIS Desktop

Arrange your map display to include the model clipping frame. The following links may help to jog your memory after an in-class demonstration. We don’t want the images to have more arcscne than we need, because this will create unnecessary problems in every thing we do subseqently. It is convenient to plan our model with a rectangular boundary. As we have explained above, one element of our arfscene model will be an image of the groundplan for our site and its tutoriao.

This will change as you use different navigation tools to move around your data and 3D environment. Get to know the ArcScene user interface. These tools optimize interacting with the 3D view and your data.

Make sure that the Clamped to Ground option is unchecked. Note that you tutorual adjust the size and rotation of symbols. In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios.


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.

In an earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation wrcscene the terrain.

We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. Save your buildings as a shapefile in your data folder. You can use the Advanced symbol swettings to read the height for each symbol from an attribute. Adjust the properties of your new tutoriaal to set their base heights and extrusion.

Beginning a 3D Modeling Project in ArcGIS

Click a tab to expand. Now that you have a 3D model you wil want to try flying around and saving some images that you can use to describe aspects of your site. Now that you know how to create new geometry and navigate to diffeent places you are ready to investigate visibility. We use this tool to export the buildings and the frame from your scene.

Your clipped groundplan image can be imported directly tutlrial Google Earth and registered precisely using your model frame. This tutorial will take this a step further. If you export an image from arcsdene with the Georeference option checked. Dockable windows collapse from the 3D view when not in use. The image will also include the outline of the frame. Export your Clipped Buildings layer. Later, you may add new subfolders to hold the resources that are used and created by other applications.

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.

Note that arcscene offers a special box for adjusting the resolution of your exported image in the View Size box at the bottom left corner of the export image turorial. This is problematic, since the Elevation units are in Meters. Rather than usng a sensible default tuyorial properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack.


We represent the column for the sign as a cylinder that has its base on the elevation surface and is extruded by 10 meters.

So if your context image is more than 4 kilometers wide, think about that. The Tools toolbar includes several navigation tools used to manipulate the observer and camera target positions.

And then change your extent or change your export resolution, the second image will have its georeferencing messed up. Our T sign is created by making a copy of our point layer. Fix it Symbology properties of your groundplan, setting Stretch to none as discussed above. To list data by source will display the storage path above the layers. The main reason for the rectangle premise is that the ground plan of the model is going to be exchanged as an image.

From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and uncheck the option for Gamma Stretch. Add your clipped DEM and your buildings and your groundplan. 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!

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 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.

Our clipped dataset is going to futorial Name your new shape file something like frame. Export a Groundplan Image Zoom out to your context frame and measure its width in meters.
