Method Detail

getUsage

String getUsage()
                throws IOException,
                       AutomationException

The usage notes of this geographic coordinate system.

Description

private void GetUsage(IGeographicCoordinateSystem geographicCoordinateSystem)
{
String usage = geographicCoordinateSystem.Usage;
System.Windows.Forms.MessageBox.Show(usage);
}

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

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

Supported Platforms

Returns:

A reference to a com.esri.arcgis.geometry.IPrimeMeridian

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getCoordinateUnit

IAngularUnit getCoordinateUnit()
                               throws IOException,
                                      AutomationException
