Direct Known Subclasses:

DefaultProjection, DefiningConversion

public class DefaultConversion

extends DefaultOperation

implements org.opengis.referencing.operation.Conversion

An operation on coordinates that does not include any change of Datum. The best-known example of a coordinate conversion is a map projection. The parameters describing coordinate conversions are defined rather than empirically derived. Note that some conversions have no parameters.

Constructor Detail

DefaultConversion

public DefaultConversion(org.opengis.referencing.operation.Conversion definition,
                         org.opengis.referencing.crs.CoordinateReferenceSystem sourceCRS,
                         org.opengis.referencing.crs.CoordinateReferenceSystem targetCRS,
                         org.opengis.referencing.operation.MathTransform transform)

Constructs a new conversion with the same values than the specified one, together with the specified source and target CRS. While the source conversion can be an arbitrary one, it is typically a defining conversion.

Parameters:

definition - The defining conversion.

sourceCRS - The source CRS.

targetCRS - The target CRS.

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

DefaultConversion

public DefaultConversion(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 conversion 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.

Method Detail

create

public static org.opengis.referencing.operation.Conversion create(org.opengis.referencing.operation.Conversion definition,
                                                                  org.opengis.referencing.crs.CoordinateReferenceSystem sourceCRS,
                                                                  org.opengis.referencing.crs.CoordinateReferenceSystem targetCRS,
                                                                  org.opengis.referencing.operation.MathTransform transform)

Returns a conversion from the specified defining conversion. This method may constructs instance of DefaultPlanarProjection or DefaultCylindricalProjection among others.

Parameters:

definition - The defining conversion.

sourceCRS - The source CRS.

targetCRS - The target CRS.

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