Abstract

Images of the topography of Australia (DTM) have been created from a digital data file of about 320 000 topographic spot heights measured during the gravity survey of Australia, resampled on a regular grid , and manipulated with a Comtal image analysis system to enhance topographic features. Three manipulations: pseudo-colour transformations, bit-plane images, and synthetic reflectance images are illustrated and discussed to give an idea of the range of computer techniques that can be used to enhance continental topography for geologic or related study. Improvements are inevitable in this new technique, which is applicable to any regional data that can be digitised, such as magnetic, gravity, or radiometric data.
