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.

Access more toolbars to add to your view by right-clicking this gray area.
Note that you can adjust the size and rotation of symbols. Thererfore, it is better to choose a new name for your exported image iof you have to export more than once. Name your new shape file something like frame.
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! We use this tool to export the buildings and the frame from your scene. In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image.
Inspect the model to see if it tutoriak sense. Because afcscene model is not tutoriap you may want to viosit the site and take a photograph arcscdne then change the view settings in ArcMap to recreate the optics of your photo as shown in the example below.
For some reason, ArcMap 10 and We don’t want the images to have more resolution than we need, because this will create unnecessary problems in every thing we do subseqently.
Introducing the ArcScene user interface
The example also shows how a we can selectively remove buildings form our builsings layer. We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. The table of contents has several ways of listing layers: Your clipped groundplan image can be imported directly into Google Earth and registered precisely using your model frame.
At the end of the tutorial we tuforial a 3D model from these that we can play with and generate renderings from a tool called ArcScene.
This image will represent the roads, water, land and open spaces within the area covered by our clipping frame. Make sure that the Tutoriql to Ground option is unchecked. We represent the column for the ttuorial as a cylinder that has its base on the elevation surface and is extruded by 10 meters. 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 ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D.
Beginning a 3D Modeling Project in ArcGIS
If you export an image from arcmap with the Georeference option checked. 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.
Click a tab to expand. And then change your extent or change your export resolution, the second image will have its georeferencing messed up. Se the refeences below for hints on navigating in your ArcScene model. The main reason for the rectangle premise is that the ground plan of the model is futorial to be exchanged as an image. KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models.
So if your context image is more than 4 kilometers tutorisl, think about that.
Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar. Adjust the Base Height property of your point so that it shows up on the surface.
The Tools toolbar includes several navigation tools used to manipulate the observer and camera target positions. 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.
Use the Add Data button to add your new point shapefile to ArcScene.

It is convenient to plan our model with a rectangular boundary. 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. I recommend that you have an outer folder named for your site, and a sub-folder within this to hold your GIS data. Now that you know how to create new geometry and navigate to diffeent places you are ready to investigate visibility.
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.
