| Abstract: | A 9 arc‐second grid of gravimetric terrain corrections has been computed over Australia using ver.2 of the 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.1 GEODATA DEM. The improved resolution is possible because of the removal of errors in ver.1 DEM. |
