Abstract

The identification of lineaments in potential field data is an important step in many interpretation projects. A method of extracting ridges and valleys based on maxima and minima of a balanced plan curvature dataset is suggested here. The method is compared with other ridge detection algorithms and is applied to aeromagnetic and gravity datasets from South Africa. Source code in Matlab format is available from the author on request.
