Method Detail

getDimension

public final int getDimension()

Returns the dimension of this coordinate system, which is 2.

Specified by:

getDimension in interface Dimensioned

Specified by:

getDimension in class CoordinateSystem

See Also:

CS_CoordinateSystem.getDimension()

getDatum

final Datum getDatum()

Override CoordinateSystem.getDatum().

Overrides:

getDatum in class CoordinateSystem

getHorizontalDatum

public HorizontalDatum getHorizontalDatum()

Returns the horizontal datum.

See Also:

CS_HorizontalCoordinateSystem.getHorizontalDatum()

getAxis

public AxisInfo getAxis(int dimension)

Gets axis details for dimension within coordinate system.

Specified by:

getAxis in class CoordinateSystem

Parameters:

dimension - Zero based index of axis.

See Also:

CS_CoordinateSystem.getAxis(int)

equivalents

public boolean equivalents(CoordinateSystem cs)

Returns true if this coordinate system is equivalents to the specified coordinate system. Two coordinate systems are considered equivalent if the CoordinateTransformation from this to cs would be the identity transform. The default implementation compare datum, units and axis, but ignore name, alias and other meta-data informations.

Overrides:

equivalents in class CoordinateSystem

Parameters:

cs - The coordinate system (may be null).

Returns:

true if both coordinate systems are equivalent.

addString

java.lang.String addString(java.lang.StringBuffer buffer)

Fill the part inside "[...]". Used for formatting Well Know Text (WKT).

Overrides:

addString in class Info

Parameters:

buffer - The buffer to add string to.

Returns:

The WKT code name (e.g. "GEOGCS").

toOpenGIS

java.lang.Object toOpenGIS(java.lang.Object adapters)

Returns an OpenGIS interface for this horizontal coordinate system. The returned object is suitable for RMI use. Note: The returned type is a generic Object in order to avoid too early class loading of OpenGIS interface.

Overrides:

toOpenGIS in class CoordinateSystem
