Terrain modeling with ArcGIS 3D Analyst

Using ArcGIS 3D Analyst, you can view extremely large sets of data in three dimensions from multiple viewpoints, query a surface, and create a realistic perspective image that drapes raster and vector data over a surface.

You can also use ArcGIS 3D Analyst to

  • Model subsurface features (e.g., wells, mines, groundwater, and underground storage facilities).
  • Calculate surface area, volume, slope, aspect, and hillshade.
  • Query data based on attributes or location.
  • Construct models via ModelBuilder and analyze results in three dimensions.
