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.

KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models.
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.
With this in mind, we should create a new folder system that will hold all of this work. To list data by source will display the storage path above the layers.
In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image. Dockable windows collapse from the 3D view when not in use. Finally, we will select and save the buildings that occur within our model study area. Thererfore, it is better to choose a new name for your exported image iof you have to export more than once.

Name this layer Removed Buildings Turn off your Groundplan so that you can see the building shapes. Our clipped dataset is going to include: Ttorial, you may add new subfolders to hold the resources that are used and created by other applications. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar.
The tutoriial reason for the rectangle premise is that the ground plan of the model is going to be exchanged as an image.
GIS Manual: Beginning a 3D Modeling Project in ArcGIS
Wil lan object theat we create be visible from key places around a site? Thinking about it another way, many programs like AutoCAD and Sketchup will choke if you try to drape a texture with more than, say x pixels Export your Buildings to a New Shape File If necessary, return to the bookmark you saved for your model frame.
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. The following notes will provide links to documentation that will provide necessary details about how to add your data, adjust the display properties and to navigate your model in 3D. Our rough 3d model can be useful for investigating how places interact visually.
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. 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.
We are beginning a new project that is going to include a new GIS dataset. And then change your extent thtorial change your export resolution, the second image will have its georeferencing arscene up. There is no 3D globe surface provided in ArcScene. In addition, certain tools and options displayed here may be specific to ArcScene and therefore not available in other applications.
You can also select or deselect toolbars from the Customize menu.
The example also shows how a arcsccene can selectively remove buildings form our builsings layer. From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer.
Introducing the ArcScene user interface
Arrange your map display to include the model clipping frame. It is convenient to plan our model with a rectangular boundary. Export your Frame polygon with the Clamped to Ground option checked.
You can quickly learn the name and more about its capabilities. Inspect the model to see if it makes sense. For the context image, you don’t necessarily need a very high-resolution image. If you export an image from arcmap with the Georeference option checked.
