Constructor Detail

CassiniSoldner

public CassiniSoldner(Ellipsoid ellipsoid,
                      Map<String,Measure> parameters)

Create a new Cassini-Soldner Projection corresponding to the Ellipsoid and the list of parameters given in argument and initialize common parameters lon0, lat0, FE, FN and other parameters useful for the projection.

Parameters:

ellipsoid - ellipsoid used to define the projection.

parameters - a map of useful parameters to define the projection.

Method Detail

getSurface

public Projection.Surface getSurface()

Return the Surface type of this Projection.

Specified by:

getSurface in class Projection

Returns:

getProperty

public Projection.Property getProperty()

Return the Property of this Projection.

Specified by:

getProperty in class Projection

Returns:

getOrientation

public Projection.Orientation getOrientation()

Return the Orientation of this Projection.

Specified by:

getOrientation in class Projection

Returns:

transform

public double[] transform(double[] coord)

Transform coord using the Cassini-Soldner Projection. Input coord is supposed to be a geographic latitude / longitude coordinate in radians. Algorithm based on the OGP's Guidance Note Number 7 Part 2 :

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - coordinate to transform

Returns:

a double array containing the output coordinate

Throws:

CoordinateDimensionException - if coord length is not compatible with this CoordinateOperation.

inverse

public Projection inverse()

Creates the inverse operation for Cassini-Soldner Projection. Input coord is supposed to be a projected easting / northing coordinate in meters. Algorithm based on the OGP's Guidance Note Number 7 Part 2 :

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class Projection
