27 * @short A Geometry object representing a 3d point
28 *
29 * GeoDataPoint is the GeoDataGeometry class representing a single three
30 * dimensional point. It reflects the Point tag of KML spec and can be contained
31 * in objects holding GeoDataGeometry objects.
32 * Nevertheless GeoDataPoint shouldn't be used if you just want to store
33 * 3d coordinates of a point that doesn't need to be inherited from GeoDataGeometry
34 * In that case use GeoDataCoordinates instead which has nearly the same features
35 * and is much more light weight.
36 * Please consider this especially if you expect to have a high
37 * amount of points e.g. for line strings, linear rings and polygons.
38 * @see GeoDataCoordinates
39 * @see GeoDataGeometry
