ITerrain Interface

Provides access to members used to acquire information about a Terrain and to retrieve DynamicSurface objects from which raster and TIN surfaces are made.

Product Availability

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

Description

The ITerrain interface is used to acquire information about a terrain and its data sources. Additionally, it's used to retrieve DynamicSurface objects which extract terrain information in the form of rasters, TINs, and measurement points.
