Class MapProjectionDisplay.MapProjection3DAdapter

java.lang.Object
visad.CoordinateSystem
ucar.unidata.view.geoloc.MapProjectionDisplay.MapProjection3DAdapter
All Implemented Interfaces:
Serializable, InverseLinearScaledCS
Enclosing class:
MapProjectionDisplay
protected class MapProjectionDisplay.MapProjection3DAdapter extends CoordinateSystem implements InverseLinearScaledCS
An adapter for visad.georef.MapProjection coordinate systems (ie: ones with * a reference of Lat/Lon). Allows for the conversion from lat/lon to Display.DisplaySpatialCartesianTuple (XYZ). Altitude (z) values are held constant.

      public MapProjection3DAdapter(MapProjection mapProjection) throws VisADException
      Construct a new CoordinateSystem which uses a MapProjection for the transformations between x,y and lat/lon.
      Parameters:
      mapProjection - CoordinateSystem that transforms from xy in the data space to lat/lon.
      Throws:
      VisADException - can't create the necessary VisAD object

    • equals

      public boolean equals(Object obj)
      See if this is equal to the object in question.
