About 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.
