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 will tutlrial this raster in the USGS group layer. 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. Like above, there are a few ways of doing this. We are beginning a new project that is going to include a new GIS dataset.
The table of contents has several ways of listing layers: We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. This wil make it very easy to register the image as with other layers as we export them to other tools. ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D. In addition, certain tools and options displayed here may be specific to ArcScene and therefore not available in other applications.
Finally, we will select and save the buildings that occur within our model study area. This will change as you use different navigation tools to move around your data and 3D environment. The main reason for the rectangle premise is that the ground plan of the model is going to be exchanged as an image. Name this layer Removed Buildings Turn off your Groundplan so that you can see the building shapes.
From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features. 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 groundplan image.
In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image. 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. Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and uncheck the option for Gamma Stretch.
Google Earth is a browser and authoring tool for georeferenced web content. Adjust the Base Height property of your point so that it shows up on the surface. Our T sign is created by making a copy of our point layer. These tools optimize interacting with the 3D view and your data.
Introducing the ArcScene user interface
Rather than usng a sensible default display properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack. Before we get into exporting the images we should think about resolution. Export your Clipped Buildings layer.
How will the removal or addition of buildings create or block views? In an earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation of the terrain. 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.
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 use this tool to export the buildings and the frame from your scene. Name your new shape file something like frame.
When saving, be sure to set Save Files of Type to Shapefile. The image will also include the outline of the frame.
And then change your extent or change your export resolution, the second image will have its georeferencing messed up. Dockable windows collapse from the 3D view when not in use. Wil lan object theat we create be visible from key places around a site?
