Interface CS_GeocentricCoordinateSystem

All Superinterfaces:

CS_CoordinateSystem, CS_Info, java.rmi.Remote

All Known Implementing Classes:

GeocentricCoordinateSystem.Export

public interface CS_GeocentricCoordinateSystem

extends CS_CoordinateSystem

A 3D coordinate system, with its origin at the center of the Earth. The X axis points towards the prime meridian. The Y axis points East or West. The Z axis points North or South. By default the Z axis will point North, and the Y axis will point East (e.g. a right handed system), but you should check the axes for non-default values.

Method Detail

getHorizontalDatum

public CS_HorizontalDatum getHorizontalDatum()
                                      throws java.rmi.RemoteException

Returns the HorizontalDatum. The horizontal datum is used to determine where the center of the Earth is considered to be. All coordinate points will be measured from the center of the Earth, and not the surface.

Throws:

java.rmi.RemoteException - if a remote method call failed.

getLinearUnit

public CS_LinearUnit getLinearUnit()
                            throws java.rmi.RemoteException

Gets the units used along all the axes.

Throws:

java.rmi.RemoteException - if a remote method call failed.

getPrimeMeridian

public CS_PrimeMeridian getPrimeMeridian()
                                  throws java.rmi.RemoteException

Returns the PrimeMeridian.

Throws:

java.rmi.RemoteException - if a remote method call failed.
