Constructor Detail

DirectTransform

public DirectTransform(PolynomialTransformation transformation,
                       CoordinateSystem sourceCRS,
                       Identifiable 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,
                       CoordinateSystem 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 Identifiable

getImplementationName

public String getImplementationName()
Specified by:
getImplementationName in class Transformation
Returns:
the name of the transformation.
