public class GeographicCoordinateReferenceSystem
extends CoordinateReferenceSystem

A geographic CoordinateReferenceSystem.

A GeographicCoordinateReferenceSystem is defined as a coordinate system based on latitude and longitude. Some geographic coordinate systems are Lat/Lon, and some are Lon/Lat. You can find out which this is by examining the CoordinateSystemAxes. You should also check the angular units, since not all geographic coordinate systems use degrees (see [CTS-1.00], p. 63).
