public class DefaultProjection

extends DefaultConversion

implements org.opengis.referencing.operation.Projection

A conversion transforming (longitude,latitude) coordinates to cartesian coordinates (x,y).

An unofficial list of projections and their parameters can be found there. Most projections expect the following parameters: "central_meridian" (default to 0), "latitude_of_origin" (default to 0), "scale_factor" (default to 1), "false_easting" (default to 0) and "false_northing" (default to 0).

Constructor Detail

DefaultProjection

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

Constructs a new projection 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:

conversion - 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.

DefaultProjection

public DefaultProjection(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 projection 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, or if not available.

targetCRS - The target CRS, or if not available.

transform - Transform from positions in the source coordinate reference system to positions in the target coordinate reference system.

method - The operation method.
