ARCSCENE TUTORIAL PDF
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.

In future tutorials, we will see how these elements can also serve as a laboratory for exploring urban design scenarios. 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.
Get to know the ArcScene user interface. KML and google earth provide many capablities for modeling sites as collections of georeferenced points, lines polygons, images and 3d models. 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.
Thererfore, it is better to choose a new name for your exported image iof you have to export more than once.
Introducing the ArcScene user interface
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 dialog. It may be helpful to make the sky blue. 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.
The Tools toolbar includes several navigation tools used to manipulate the observer and camera target positions. We are beginning a new project that is going to include a new GIS dataset.
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 The following links may help to jog your memory after an in-class demonstration.

For some reason, ArcMap 10 and From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. Because your model is not perfect you may want to viosit the site and take a photograph and then change the view settings in ArcMap to recreate the optics of your photo as shown in the example below.
This wil make it very easy to register the image as with other layers as we export them to other tools. We tuotrial going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. Dockable windows collapse from the 3D view when not in use.
When saving, be sure to set Save Files of Type to Shapefile.
Beginning a 3D Modeling Project in ArcGIS
In an earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation of the terrain.
Our clipped dataset is going to include: We use this tool to export the buildings and the frame from your scene. Save your buildings as a shapefile in your data folder.
With this in mind, we should create a new folder system that will hold all of this work. And then change your extent or change your export resolution, the second image will have its georeferencing messed up.
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. I recommend that you have an outer folder named for your site, and a sub-folder within this to hold your GIS data.
Adjust the properties of your new building to set their base heights and extrusion. 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. This image will represent the roads, water, land and open spaces within the area covered by our clipping frame. Now that you know how to create new geometry and navigate to diffeent places you are ready to investigate visibility.
It is convenient to plan our model with a rectangular boundary. In the Export Map Dialog, you should check arxscene option to Save World Filewhich will save some georeferencing information for the image. So if your context image is more than 4 kilometers wide, think about that.
To list data by source will display the storage path above the layers.
Export arcdcene Clipped Buildings layer. The main reason for the rectangle premise is that the ground plan of the model is going to be exchanged as an image.
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. Because we want to make a nice compact 3d model, we will export a clip of the elevation model using the same extent that we used to export the arcscdne image.
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.
GIS Manual: Beginning a 3D Modeling Project in ArcGIS
Export a Groundplan Image Zoom out to your context frame and measure its width in meters. The table of contents has several ways of listing layers: Name your new shape file something like frame. Export your Frame polygon with the Clamped to Ground option checked. Use acscene Add Data button to add your new point shapefile to ArcScene. For Location choose your data folder. From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features.
This tutorial will take this a step further.
