SAGA.grid_calculus.16: Gradient Vector from Polar to Cartesian Coordinates

Converts gradient vector from polar coordinates (direction or aspect angle and length or tangens of slope) to directional components (Cartesian).<br/>The tool supports three conventions on how the angle of direction can be supplied:<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/>
