Airborne laser swath mapping of the Denton Hills, Transantarctic Mountains, Antarctica: Applications for structural and glacial geomorphic mapping

High-resolution digital elevation data acquired by airborne laser scanning (ALS) for the Denton Hills, along
the coastal foothills of the Royal Society Range, Transantarctic Mountains, are examined for applications to bedrock
and glacial geomorphic mapping. Digital elevation models (DEMs), displayed as shaded-relief images and slope maps,
portray geomorphic landscape features in unprecedented detail across the region. Structures of both ductile and brittle
origin, ranging in age from the Paleozoic to the Quaternary, can be mapped from the DEMs. Glacial features, providing
a record of the limits of grounded ice, of lake paleoshorelines, and of proglacial lake-ice conveyor deposits, are also
prominent on the DEMs. The ALS-derived topographic data have great potential for a range of mapping applications in
regions of ice-free terrain in Antarctica
