Constructor Detail

Projection

public Projection(String name,
                  String classification,
                  Ellipsoid ellipsoid,
                  Point2D centre,
                  Point2D translation,
                  double scaleFactor)

Convenience constructor for a projection using the specified ellipsoid.

Parameters:

name - Name to give new object.

classification - Classification string for projection (e.g. "Transverse_Mercator").

ellipsoid - Ellipsoid parameter. If non-null, then "semi_major" and "semi_minor" parameters will be set according.

centre - Central meridian and latitude of origin, in degrees. If non-null, then "central_meridian" and "latitude_of_origin" will be set according.

translation - False easting and northing, in metres. If non-null, then "false_easting" and "false_northing" will be set according.

Projection

public Projection(String name,
                  String classification,
                  javax.media.jai.ParameterList parameters)

Creates a projection. The set of parameters (parameters) may be queried with MathTransformFactory.getMathTransformProvider(classification).getParameterList().

Parameters:

name - Name to give new object.

classification - Classification string for projection (e.g. "Transverse_Mercator").

parameters - Parameters to use for projection, in metres or degrees.

Projection

Projection(Map properties,
           String classification,
           javax.media.jai.ParameterList parameters)

Creates a projection.

Parameters:

properties - The set of properties (see Info).

classification - Classification string for projection (e.g. "Transverse_Mercator").

parameters - Parameters to use for projection, in metres or degrees.

Method Detail

getParameterList

static javax.media.jai.ParameterList getParameterList(String classification)

Returns a parameter list for the specified classification. If there is no special parameter descriptor for the specified classification, then a default descriptor is used.

Parameters:

classification -

Returns:

a parameter list for the specified classification. If there is no special parameter descriptor for the specified classification, then a default descriptor is used.

init

static javax.media.jai.ParameterList init(javax.media.jai.ParameterList parameters,
                                          Ellipsoid ellipsoid,
                                          Point2D centre,
                                          Point2D translation,
                                          double scaleFactor)

Initialize a list of parameter from the specified ellipsoid and points.

Parameters:

parameters - The parameters to initialize.

ellipsoid - Ellipsoid parameter. If non-null, then "semi_major" and "semi_minor" parameters will be set according.

centre - Central meridian and latitude of origin, in degrees. If non-null, then "central_meridian" and "latitude_of_origin" will be set according.

translation - False easting and northing, in metres. If non-null, then "false_easting" and "false_northing" will be set according.

scaleFactor -

Returns:

parameters for convenience.

getClassName

public String getClassName()
