public class DefaultTransformation

extends DefaultOperation

implements org.opengis.referencing.operation.Transformation

An operation on coordinates that usually includes a change of Datum. The parameters of a coordinate transformation are empirically derived from data containing the coordinates of a series of points in both coordinate reference systems. This computational process is usually "over-determined", allowing derivation of error (or accuracy) estimates for the transformation. Also, the stochastic nature of the parameters may result in multiple (different) versions of the same coordinate transformation.

Constructor Detail

DefaultTransformation

public DefaultTransformation(java.util.Map properties,
                             org.opengis.referencing.crs.CoordinateReferenceSystem sourceCRS,
                             org.opengis.referencing.crs.CoordinateReferenceSystem targetCRS,
                             org.opengis.referencing.operation.MathTransform transform,
                             org.opengis.referencing.operation.OperationMethod method)

Constructs a transformation from a set of properties. The properties given in argument follow the same rules than for the AbstractCoordinateOperation constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

sourceCRS - The source CRS.

targetCRS - The target CRS.

transform - Transform from positions in the source CRS to positions in the target CRS.

method - The operation method.
