Lineament analysis for the McMurdo Dry Valleys region, Antarctica
Light Detecting and Ranging (LiDAR) data were collected for regions spanning approximately 4000 km² in the McMurdo Dry Valleys region of Antarctica. The efficacy of using digital elevation models (DEMs) derived from these data for geomorphic mapping applications in the Dry Valleys are assessed. Usi...
