Abstract

Complete Bouguer corrections have been computed over the Australian mainland and Tasmania on a 9 arc-second grid (~250 m spatial resolution) from version 2 of the GEODATA digital elevation model (DEM) of Australia. These include the Bouguer plate correction to the geoid (mean sea level) and the planar terrain correction residual to this plate out to a radius of 50 km (beyond Hammer zone M). A constant topographic density of 2670 kg.m-3 has been used for both correction terms. The terrain corrections were computed using a planar two-dimensional fast Fourier transform (FFT) algorithm.
