26 * @short A class that defines a 3D bounding box for geographic data.
27 *
28 * GeoDataLatLonAltBox is a 3D bounding box that describes a geographic area
29 * in terms of latitude, longitude and altitude.
30 *
31 * The bounding box gets described by assigning the northern, southern,
32 * eastern and western boundary.
33 * So usually the value of the eastern boundary is bigger than the
34 * value of the western boundary. Only if the bounding box crosses the
35 * date line then the eastern boundary has got a smaller value than
36 * the western one.
