Gradient Vector from Cartesian to Polar Coordinates
Victor Olaya & Volker Wichmann (c) 2004-2010
Converts gradient vector from directional components (Cartesian) to polar coordinates (direction or aspect angle and length or tangens of slope).
The module supports three conventions on how to measure and output the angle of direction:
(a) mathematical: direction angle is zero in East direction and the angle increases counterclockwise
(b) geographical: direction angle is zero in North direction and the angle increases clockwise
(c) zero direction and orientation are user defined
