Comparison of approximation methods for partial derivatives of surfaces on regular grids
Original language description
In many GIS is implemented the approximation of partial derivatives of the 1st and the 2nd order. These derivatives are further used for computation of surfaces of derived morphometrical variables as slope, aspect and different types of curvatures. In geomorphologic researche are often required surfaces of derived morphometrical variables of the 3rd order. It is impossible to approximate the partial derivatives of the 3rd order with sufficient quality by tools offered in a common GIS. In this paper is presented and tested a method for this approximation fulfilling the accuracy requirements.
