Perform spatial analyses and mappings by importing geometric data from DTMs.

• Import geometric data from an existing digital terrain model (DTM) within ArcInfo, in the form of triangulated irregular networks (TINs).
• Create coverages within ArcInfo to represent the attributes associated with a river, such as cross-section geometry, bank stations, and so forth.
• Import HEC-RAS water surface profiles back into HEC-GIS to perform additional spatial analyses and mappings.
