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.

With this in mind, we should create a new folder system that will hold all of this work. Our rough 3d model can be useful for investigating how places interact visually. Access more toolbars to add to your view by right-clicking this gray area. This image will represent the roads, water, land and open spaces within the area covered by our clipping frame.
Arrange your map display to include the model clipping frame. You will find this raster in the USGS group layer. Wil lan object theat we create be visible from key places around a site? We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. Get to know the ArcScene user interface.
For some reason, ArcMap 10 and Adjust the properties of your new building to set their base heights and extrusion. From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features. From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. Rather than usng a sensible default display properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack.
There arcsscene no 3D tutorizl surface provided in ArcScene. When saving, be sure to set Save Files of Type to Shapefile. The Tools toolbar includes several navigation tools used to manipulate the observer and camera target positions. Export your Clipped Buildings layer. A good resolution for your context image may be about a half-meter per pixel, which is good tutroial to see distinguish buildings, roads, cars, etc. You may want to use other overlays with transparency to colorize the photograph or to include details for some other GIS layer that you have.
We represent the column for the sign as a cylinder that has its base on the elevation surface and is extruded by srcscene meters.
Introducing the ArcScene user interface
And images are always rectangular. In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios.
Our clipped dataset is going to include: Save your buildings as a shapefile in your data folder. ToolTips are revealed when you hover over a tool on arcscnee toolbar.
It may be helpful to make the sky blue. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar. 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. This will change as you use different navigation tools to move around your tutoriial and 3D environment.
These tools optimize interacting with the 3D view and your data. Name your new shape file something like frame.
This tutorial will take this a step further. 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. 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. Then we can navigate to different places in the model check whether the sign is visible.
Export your Buildings to a New Shape File If necessary, return to the bookmark you saved for your model frame. tuforial
Our T sign is created by making a copy of our point layer. Click a tab to expand. 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. The table of contents has several ways of listing layers: Adjust the Base Height property of your point so that it shows up on the surface. Finally, we will select and save the buildings that occur within our model study area.
Shift-click to select more than obne building.
GIS Manual: Beginning a 3D Modeling Project in ArcGIS
This is problematic, since the Elevation units are in Meters. So if your context image is more than 4 kilometers wide, think about that. Thererfore, it is better to choose a new name for your exported image iof you have to export more than once. Se the refeences below for hints on navigating in your ArcScene model. ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D.
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.
Fix it Symbology properties of your groundplan, setting Stretch to none as discussed above. Note that you can adjust the size and rotation of symbols. For Location choose your data folder. As we have explained above, one element of our site model will be an image of the groundplan for our site and its context. KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models.
Note that dockable window controls can be moved around the display to customize your view.
