Remarks

The output DEM is suitable only for visual preview.

The algorithm doesn't take the coordinate system into account thus the result values are just rough approximations.

Generator assumes that x, y and z (elevation) units are identical. If x and y units are identical, but z units are different, the scale parameter of the operation can be used to set the ratio of vertical units to horizontal. For projections near the equator, where units of latitude and longitude are similar, elevation (z) units can be converted by using scale 370400 (feet) or 111120 (meters).
