Constructor Detail

IlvWKTCoordinateSystemFactory

public IlvWKTCoordinateSystemFactory()

Creates a new default coordinate system factory, with default projection and datum factories.

IlvWKTCoordinateSystemFactory

public IlvWKTCoordinateSystemFactory(IlvWKTProjectionFactory projFactory,
                                     IlvWKTDatumFactory datumFactory)

Creates a new coordinate system factory, with the specified projection and datum factories.

Method Detail

getProjectionFactory

public IlvWKTProjectionFactory getProjectionFactory()

Returns the projection factory used by this coordinate system factory.

getDatumFactory

public IlvWKTDatumFactory getDatumFactory()

Returns the datum factory used by this coordinate system factory.

isIgnoringUnknownDatums

public boolean isIgnoringUnknownDatums()

Returns true if this factory ignores unknown datums and replaces all unknown datums with a WGS 84 datum.
This coordinate system factory ignores unknown datum by default.
If this property is false and the fromWKT method encounters an unknown datum, it throws an IllegalArgumentException.

Returns:

true if this factory ignores unknown datums.

setIgnoringUnknownDatums

public void setIgnoringUnknownDatums(boolean set)

Sets whether this factory ignores unknown datums and replaces all unknown datums with a WGS 84 datum.

Parameters:

set - If true if this factory ignores unknown datums.

fromWKT

public IlvCoordinateSystem fromWKT(String wkt)
                            throws IlvProjectionException

Returns the coordinate system described by the specified WKT.

Parameters:

wkt - The Well Known Text.

Returns:

The decoded IlvCoordinateSystem or null if the specified WKT does not encode a coordinate system known to JViews.

Throws:

IlvProjectionException - If the WKT encodes a projection with bad parameters.

IllegalArgumentException - If the WKT cannot be decoded.

toWKT

public String toWKT(IlvCoordinateSystem cs)

Returns the WKT representation of the specified IlvCoordinateSystem.

toWKT

public String toWKT(IlvProjectedCoordinateSystem cs)

Returns the WKT representation of the specified IlvProjectedCoordinateSystem.

toWKT

public String toWKT(IlvGeographicCoordinateSystem cs)

Returns the WKT representation of the specified IlvGeographicCoordinateSystem.

toWKT

public String toWKT(IlvGeocentricCoordinateSystem cs)

Returns the WKT representation of the specified IlvGeocentricCoordinateSystem.

toWKT

public String toWKT(IlvMeridian meridian,
                    IlvAngularUnit unit)

Returns the WKT representation of the specified IlvMeridian, using the specified unit to express the longitude.

toWKT

public String toWKT(IlvUnit unit)

Returns the WKT representation of the specified IlvUnit.
