Abstract

This paper begins with brief descriptions of how gamma ray data are collected from aircraft, the relationship between gamma ray signatures, and the properties of underlying rock and regolith. A methodology for identifying the particular spatial patterns associated with erosion and deposition is described and applied to gamma ray data from small drainage basins in southeastern Australia. A short review of digital elevation model (DEM) generation from geophysical survey data is also presented since this may be a substitute for a more conventional approach in which DEMs are generated from contour data derived by photogrammetry
