Terrain analysis of the Keller Peninsula (King George Island, Antarctica) by gis techniques
This study uses a Geographical Information System (GIS) for terrain analysis of the Keller Peninsula (KP), King George Island (KGI), Antarctica, to describe its morphological characteristics. We processed a vertical metric aerial photography and a DigitalTerrain Model(DTM)in a Digital Photogrammetri...
