Airborne magnetic surveys have long been a primary tool for geologic mapping, resource exploration, hazard evaluation and tectonic studies. Recent advances in precise positioning have enabled other geophysical tools such as laser and radar altimeters and the gravity meter to be mounted on airplanes and contribute to geologic and environmental studies. The principal advantages of airborne geophysical surveys over ground based studies result from enhanced experiment design including; improved access to remote and contaminated areas, optimized sampling, rapid sampling rate and tremendous potential for interdisciplinary studies.
