Constructor Detail

DirectTransform

public DirectTransform(PolynomialTransformation transformation,
                       CRS sourceCRS,
                       CRSResource id)

Parameters:

transformation - to apply

sourceCRS - in which the points will be defined.

id - an identifiable instance containing information about this transformation

DirectTransform

public DirectTransform(PolynomialTransformation transformation,
                       CRS sourceCRS)

Parameters:

transformation - to apply

sourceCRS - in which the points will be defined.

Method Detail

doTransform

public List<javax.vecmath.Point3d> doTransform(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 String toString()

Overrides:

toString in class CRSIdentifiable

getImplementationName

public String getImplementationName()

Specified by:

getImplementationName in class Transformation

Returns:

the name of the transformation.
