3D Analyst

ArcGIS 3D Analyst is an extension to ArcGIS for Desktop that allows you to effectively visualize and analyze surface data. By using ArcGIS 3D Analyst, you can view a surface from multiple viewpoints, query a surface, determine what is visible from a chosen location on a surface, create a realistic perspective image that drapes raster and vector data over a surface, and record or perform three-dimensional (3D) navigation.
