Abstract
The conventional approach of computing a gravity topographic correction from digital elevation<br>models (DEM) involves creating a correction grid at a station by means of interpolation. Obviously, the<br>interpolation process introduces errors in the estimated elevation of the grid points that result in noise of<br>the computed topographic correction.
