ArcObjects Library Reference (GeoDatabaseExtensions)

Terrain Class

The Esri Terrain component.

Terrain is a non-creatable object. References to non-creatable objects must be obtained through other objects.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

A Terrain is used to define a surface based on vector measurements stored in the geodatabase. Terrains live inside feature datasets and are comprised of one or more feature classes and rules. Rules govern how the measurements associated with each feature class contribute to define the surface.
