Class RotatedOffsetProjection

  • All Implemented Interfaces:
    Serializable, ucar.unidata.geoloc.Projection
    public class RotatedOffsetProjection
extends ucar.unidata.geoloc.ProjectionImpl
    A Projection which defines a rotated and offset grid in an arbitrary CRS. This does not support all of the methods of Projection, but rather only those which are required by CdmTransformedGrid. To clarify, coordinates in this projection need to be rotated clockwise by an angle and then shifted by an offset before they are then in the correct geographic position in the supplied CRS. They therefore need to be transformed from that CRS to CRS:84 to give a lat-lon position.
