IGeographicCoordinateSystem Interface

Provides access to members that control access to all properties of geographic coordinate systems. Note: the IGeographicCoordinateSystem interface has been superseded byIGeographicCoordinateSystem2. Please consider using the more recent version.

Product Availability

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

Description

A geographic coordinate system is defined (at minimum) by a name, an angular unit of measure, a horizontal datum, and a prime meridian.
