Examples of org.geotools.referencing.crs.DefaultGeographicCRS

org.geotools.referencing.crs.DefaultGeographicCRS
A coordinate reference system based on an ellipsoidal approximation of the geoid; this provides an accurate representation of the geometry of geographic features for a large portion of the earth's surface.
