Converts an angle measured in degrees to an equivalent angle measured in radians.
Converts an angle measured in radians to an equivalent angle measured in degrees.
The following MEP functions are not part of the Odysseus Core and may be restricted.
The spatial functions are based upon the JTS Topology Suite (http://www.vividsolutions.com/jts/JTSHome.htm).
Notice, that JTS only considers x and y coordinate and ignores the z coordinate (although z can be definied)!
