Abstract

A 9 arc-second grid of gravimetric terrain corrections has been computed over Australia using ver.2 ofthe GEODATA 9 arc-second digital elevation model (DEM) and the fast Fourier transform technique.This supersedes the 27 arc-second grid previously reported in this journal, computed from ver.1GEODATA DEM. The improved resolution is possible because of the removal of errors in ver.1 DEM.
