Class MapProjectionDisplay.MapProjection3DAdapter

java.lang.Object
  visad.CoordinateSystem
      ucar.unidata.view.geoloc.MapProjectionDisplay.MapProjection3DAdapter

All Implemented Interfaces:

Serializable

Enclosing class:

MapProjectionDisplay

protected static class MapProjectionDisplay.MapProjection3DAdapter
extends CoordinateSystem

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.

MapProjectionDisplay.MapProjection3DAdapter

public MapProjectionDisplay.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.

Specified by:

equals in class CoordinateSystem

Parameters:

obj - object in question.

Returns:

true if they are equal. The two objects are equal if their MapProjections are equal.

getMapProjection

public MapProjection getMapProjection()

Return the MapProjection being used by the CoordinateSystem.

Returns:

the MapProjection used in this instance
