A bstract A method is described in which various gravity maps (regional, residual, first and second derivatives, upward and downward continuation, etc….) may be quickly constructed, without manual plotting and visual interpolation, which are often a source of error. The coordinates and the g ‐values ( x, y and g ) of the field stations are introduced into the electronic computer on perforated cards. The computations are carried out by means of a hexagonal network. The computed values and their respective positions on the network are plotted directly on a sheet of paper by the electronic computer. The map is obtained by assembling these sheets and contouring.
