SAGA.grid_calculus.15: Gradient Vector from Cartesian to Polar Coordinates

Converts gradient vector from directional components (Cartesian) to polar coordinates (direction or aspect angle and length or tangens of slope).<br/>The tool supports three conventions on how to measure and output the angle of direction:<br/>(a) mathematical: direction angle is zero in East direction and the angle increases counterclockwise<br/>(b) geographical: direction angle is zero in North direction and the angle increases clockwise<br/>(c) zero direction and orientation are user defined<br/>
