public interface CoordinateReferenceSystem
extends Identifiable

A coordinate system which is related to the real world by a Datum (ISO/DIS 19111).

A point in the real world may have different coordinates, depending on the CoordinateReferenceSystem used. The different types of CoordinateReferenceSystem defined by EPSG are :

• Geocentric coordinate reference system
• Geographic 3D coordinate reference system
• Geographic 2D coordinate reference system
• Projected coordinate reference system
• Vertical coordinate reference system
• Compound coordinate reference system
• Engineering coordinate reference system

Method Detail

getType

CoordinateReferenceSystem.Type getType()

Returns this CoordinateReferenceSystem Type.

getCoordinateSystem

CoordinateSystem getCoordinateSystem()

Returns the CoordinateSystem used by this CoordinateReferenceSystem.

getDatum

Datum getDatum()

Returns the Datum to which this CoordinateReferenceSystem is refering. For compound CoordinateReferenceSystem, getDatum returns the the main datum, ie the GeodeticDatum (or horizontal Datum).

getProjection

Projection getProjection()

Returns the Projection to which this CoordinateReferenceSystem is refering. It returns null if no projection is defined for this CRS.

toWKT

String toWKT()

Returns a WKT representation of the CoordinateReferenceSystem.
