IGeographicCoordinateSystem2 Interface

Provides access to members that control additional properties and methods for all geographic coordinate systems.

Product Availability

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

When To Use

Use IGeographicCoordinateSystem2 when you need to work with map projection horizons or transform between two geographic coordinate systems.

Members

Description
Read-only property Abbreviation The abbreviated name of this spatial reference component.
Read-only property Alias The alias of this spatial reference component.
Read-only property AngularConversionFactor A factor to convert angular units from current GCS to destination GCS.
Method Changed Notify this object that some of its parts have changed (parameter values, z unit, etc.).
Read-only property CoordinateUnit The angular unit of this geographic coordinate system.
Read-only property Datum The horizontal datum of this geographic coordinate system.
Write-only property ExtentHint Calculates a 360 degree longitude range from information in the specified envelope and the domain extent of the GCS.
Read-only property FactoryCode The factory code (WKID) of the spatial reference.
