6.6.2. Surface Analysis

The Surface Toolset in ArcGIS allows you to calculate and visualize different properties of the terrain from an input DEM (see section 3.2.4.). The surface toolset is part of the Spatial Analyst toolbox in ArcGIS. In the following section we will perform calculations based on the same 30 m DEM introduced earlier. For the next sections, one of either Spatial or 3D Analyst extensions is required. To turn on extensions select Customize > Extensions from the main menu. If you do not own a license, you will get a message when you try to click an extension.
