org.geotools.referencing.operation.projection.IdrEquidistantCylindrical

Direct Known Subclasses:

IdrPlateCarree

public class IdrEquidistantCylindrical
extends MapProjection

Equidistant cylindrical projection (EPSG code 9823). In the particular case where the standard_parallel_1 is 0, this projection is also called Plate Carree or Equirectangular. This is used in, for example, WGS84 / Plate Carree (EPSG:32662). References:
