The use of RADARSAT-1 imagery for lithological and structural mapping in the Canadian High Arctic.
RADARSAT-1 images of the northern part of Axel Heiberg Island were acquired to define a selection of preferable beam modes for geological mapping in this cold and arid environment with locally rugged topography. Fine, Standard, and Extended High beam mode images with different resolutions, areas of...
