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.

You can also select or deselect toolbars from the Customize menu. Save your buildings as a shapefile in your data folder. And images are always rectangular. 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.
Use the Add Data button to add your new point shapefile to ArcScene. You should now be able to add your groundplan image to ArcMap. We use this tool to export the buildings and the frame from your scene. Wil lan object theat we create be visible from key places around a site? 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.
Name this layer Removed Buildings Turn off your Groundplan so that you can see the building shapes. 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. 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.
Shift-click to select more than obne building.
GIS Manual: Beginning a 3D Modeling Project in ArcGIS
Name your new shape file something like frame. When asked whether you want to build Pyramid Layerssay yes.
Click a tab to expand. Your clipped groundplan image can be imported directly into Google Tuforial and registered precisely using your model frame. For Location choose your data folder. Note that you can adjust the size and rotation of symbols.
Introducing the ArcScene user interface
Arcscenr a Groundplan Image Zoom out to your context frame and measure its width in meters. Then we have everything we need to make a nice compact 3d model of our site!
Open your geoprocessing toolbox by clicking the little uttorial toolbox icon on ArcScene’s toolbar. Rather than usng a sensible default display properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack.
ToolTips are revealed when you hover over a tool on a toolbar. There is no 3D globe surface provided in ArcScene. In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios. Get to know the ArcScene user interface.
If you export an image from arcmap with the Georeference option checked. To list data by source will display the storage path above the layers. This tutorial will take this a step further. 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 will find this raster in the USGS arcscnee layer. Note that arcscene offers a special box for adjusting the resolution of your exported image in the Tutoriao Size box at the bottom left corner of the export image dialog.
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 You can use the Advanced symbol swettings to read the height for each symbol from an attribute. Before we get into exporting the images we should think about resolution. We are beginning a new project that is going to include a new GIS dataset.
Use this image as a beginning guide to familiarize yourself with the ArcScene environment. Export your Clipped Buildings layer. So if your context image is more than 4 kilometers wide, think about that. Adjust the properties of your new building to set their base heights and extrusion.
Access more toolbars to add to your view by right-clicking this gray area. Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and arcsceen the option tutoriwl Gamma Stretch.
I recommend that you have an outer folder named for your site, and a sub-folder within this to hold your GIS data. Dockable windows collapse from the 3D view when not in use. 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.
