@UML(identifier="SC_CRS", specification=ISO_19111) public interface CoordinateReferenceSystem extends ReferenceSystem
The concept of coordinates may be expanded from a strictly spatial context to include time. Time is then added as another coordinate to the coordinate tuple. It is even possible to add two time-coordinates, provided the two coordinates describe different independent quantities. An example of the latter is the time/space position of a subsurface point of which the vertical coordinate is expressed as the two-way travel time of a sound signal in milliseconds, as is common in seismic imaging. A second time-coordinate indicates the time of observation, usually expressed in whole years.
|Modifier and Type||Method and Description|
Returns a relevant coordinate system instance.
@Extension CoordinateSystem getCoordinateSystem()
If the CRS instance on which this method is invoked is an instance of the compound CRS interface, then the CS instance which is returned shall have dimension and axis components obtained from different components of the instance CRS.
