Anomalously Large Gradients in Version 1 of the "GEODATA 9 SECOND" Digital Elevation Model of Australia, and their Effects on Gravimetric Terrain Corrections

Large gradients, when calculated by a first-difference method, have been detected in the 9 arc-second National Digital Elevation Model (DEM) of Australia released by the Australian Surveying and Land Information Group. Gradient values implied by the mean elevations in the DEM between adjacent grid c...
