Class MapProjectionDisplay.MapProjection3DAdapter

java.lang.Object

visad.CoordinateSystem

ucar.unidata.view.geoloc.MapProjectionDisplay.MapProjection3DAdapter

All Implemented Interfaces:

java.io.Serializable, visad.InverseLinearScaledCS

Enclosing class:

MapProjectionDisplay

protected class MapProjectionDisplay.MapProjection3DAdapter
extends visad.CoordinateSystem
implements visad.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.

MapProjection3DAdapter

public MapProjection3DAdapter(visad.georef.MapProjection mapProjection)
                       throws visad.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:

visad.VisADException - can't create the necessary VisAD object
