Constructor Detail

ProjectedCRSRef

public ProjectedCRSRef(ReferenceResolver resolver,
                       String uri,
                       String baseURL)

Creates a reference to a ProjectedCRS

Parameters:

resolver - used for resolving the reference, must not be null

uri - the object's uri, must not be null

baseURL - base URL for resolving the uri, may be null (no resolving of relative URLs)

Method Detail

getReferencedObject

public ProjectedCRS getReferencedObject()

Description copied from class: Reference

Returns the referenced Object instance (may trigger resolving and fetching it).

Overrides:

getReferencedObject in class CRSRef

Returns:

the referenced Object instance

getGeographicCRS

public IGeographicCRS getGeographicCRS()

Specified by:

getGeographicCRS in interface IProjectedCRS

Returns:

the underlyingCRS.

getProjection

public IProjection getProjection()

Specified by:

getProjection in interface IProjectedCRS

Returns:

the projection.

doProjection

public javax.vecmath.Point2d doProjection(double lambda,
                                          double phi)
                                   throws ProjectionException

Description copied from interface: IProjectedCRS

The actual transform method doing a projection from geographic coordinates to map coordinates.

Specified by:

doProjection in interface IProjectedCRS

Parameters:

lambda - the longitude

phi - the latitude

Returns:

the projected Point or Point(Double.NAN, Double.NAN) if an error occurred.

Throws:

ProjectionException - if the given lamba and phi coordinates could not be projected to x and y.

doInverseProjection

public javax.vecmath.Point2d doInverseProjection(double x,
                                                 double y)
                                          throws ProjectionException

Description copied from interface: IProjectedCRS

Do an inverse projection from projected (map) coordinates to geographic coordinates.

Specified by:

doInverseProjection in interface IProjectedCRS

Parameters:

x - coordinate on the map

y - coordinate on the map

Returns:

the projected Point with x = lambda and y = phi;

Throws:

ProjectionException - if the given x and y coordinates could not be inverted to lambda and phi.

equals

public boolean equals(Object obj)

Overrides:

equals in class CRSRef
