public class Altitude2EllipsoidalHeight
extends AbstractCoordinateOperation
implements GridBasedTransformation

Altitude2EllipsoidalHeight is a coordinate operation used to transform 3D coordinates containing the altitude in the third coordinate with a grid transformation that return the equivalent coordinates with ellipsoidal height instead of altitude.

Altitude2EllipsoidalHeight

public Altitude2EllipsoidalHeight(String nameGrid,
                                  GeodeticDatum gd)
                           throws Exception

Altitude translation with parameter interpolated from a grid depending on the geographic coordinates of the point to convert.

Parameters:

nameGrid - the name of the grid file to use

gd - the geodetic datum in which the geographic coordinates used in the interpolation must be expressed

Throws:

Exception

Method Detail

getAssociatedDatum

public GeodeticDatum getAssociatedDatum()

Return the geodetic datum associated to this transformation. The latitude and longitude of the coordinate must be expressed in this datum to obtain good results.

Returns:

getGridFileName

public String getGridFileName()

Return the name of the grid file used to define this transformation.

transform

public double[] transform(double[] coord)
                   throws IllegalCoordinateException

Description copied from class: AbstractCoordinateOperation

Return a double[] representing the same location as coord but in another CoordinateReferenceSystem.

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - the input coordinate

Returns:

a double array containing the output coordinate

Throws:

IllegalCoordinateException - if coord is not compatible with this CoordinateOperation.

inverse

public CoordinateOperation inverse()
                            throws NonInvertibleOperationException

Creates the inverse CoordinateOperation.

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class AbstractCoordinateOperation

Throws:

NonInvertibleOperationException
