Method Detail

getUsage

String getUsage()
                throws IOException,
                       AutomationException
The usage notes of this geographic coordinate system.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:
The usage
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getDatum

IDatum getDatum()
                throws IOException,
                       AutomationException
The horizontal datum of this geographic coordinate system.

Description

Returns the vertical or horizontal datum of the vertical coordinate system as IHVDatum. QI with IVerticalDatum or IDatum. A vertical datum means that the VCS is gravity-related. A (horizontal) datum means that the VCS is ellipsoid/spheroid-based.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:
A reference to a com.esri.arcgis.geometry.IDatum
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getPrimeMeridian

IPrimeMeridian getPrimeMeridian()
                                throws IOException,
                                       AutomationException
The prime meridian of this geographic coordinate system.

Product Availability
