ArcObjects Library Reference (Geometry)

ISpatialReference3 Interface

Provides access to additional members that associate a spatial reference with a vertical coordinate system.

Product Availability

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

When To Use

Use ISpatialReference3 to work with the vertical coordinate system part of a spatial reference.
