@Immutable
public class LambertAzimuthalEqualArea
extends MapProjection

The provider for "Lambert Azimuthal Equal Area" projection (EPSG:9820, EPSG:1027).

Note: EPSG defines two codes for this projection, 1027 being the spherical case and 9820 the ellipsoidal case. However the formulas are the same in both cases. Consequently they are implemented in Geotk by the same class.

The programmatic names and parameters are enumerated at Lambert Azimuthal Equal Area on RemoteSensing.org. The math transform implementations instantiated by this provider may be any of the following classes:

• LambertAzimuthalEqualArea
