@Immutable
public class PseudoMercator
extends MapProjection

The provider for "Popular Visualisation Pseudo Mercator" projection (EPSG:1024). This is also known as the "Google projection", defined by popular demand but not considered a valid projection method.

The math transform implementations instantiated by this provider may be any of the following classes:

• Mercator

The following table summarizes the parameters recognized by this provider. For a more detailed parameter list, see the PARAMETERS constant.
