Constructor Detail

ProjectionTransform

public ProjectionTransform(ProjectedCRS projectedCRS,
                           Identifiable id)

Parameters:

projectedCRS - The crs containing a projection.

id - an identifiable instance containing information about this transformation

ProjectionTransform

public ProjectionTransform(ProjectedCRS projectedCRS)

Parameters:

projectedCRS - The crs containing a projection.

Method Detail

doTransform

public java.util.List<javax.vecmath.Point3d> doTransform(java.util.List<javax.vecmath.Point3d> srcPts)
                                                  throws TransformationException

Description copied from class: Transformation

Do a transformation, e.g. the incoming data will be transformed into other coordinates.

Specified by:

doTransform in class Transformation

Parameters:

srcPts - the points which must be transformed, expected are following values either, long_1, lat_1, height_1, long_2, lat_2, height_2. or long_1, lat_1, long_2, lat_2

Returns:

the transformed points

Throws:

TransformationException - if a transform could not be calculated.

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in class Transformation

Returns:

true if this transformation doesn't transform the incoming points. (e.g. is the id. matrix)

toString

public java.lang.String toString()

Overrides:

toString in class Identifiable

getImplementationName

public java.lang.String getImplementationName()

Specified by:

getImplementationName in class Transformation

Returns:

the name of the transformation.
