public Quantity<Length> getNorthing()

getEllipsoid

public ReferenceEllipsoid getEllipsoid()

Description copied from interface: EarthCoordinate

Returns the reference ellipsoid used by this coordinate.

Specified by:

getEllipsoid in interface EarthCoordinate

Returns:

the ellipsoid model

getCoordinateSystem

public String getCoordinateSystem()

Description copied from interface: EarthCoordinate

Returns the coordinate system name (e.g., "WGS84", "UTM", "MGRS").

Specified by:

getCoordinateSystem in interface EarthCoordinate

Returns:

the coordinate system identifier

toECEF

public ECEFCoordinate toECEF()

Description copied from interface: EarthCoordinate

Converts this coordinate to ECEF Cartesian form.

Specified by:

toECEF in interface EarthCoordinate

Returns:

the ECEF representation

dimension

public int dimension()

Description copied from interface: GeometricObject

Returns the intrinsic dimension of this geometric object.

Examples:

• Point: 0
• Line/Segment: 1
• Plane/Surface: 2
• Volume: 3

Specified by:
