The central objective of this project has been the development of geostatistical methods fro mapping elevation and ice surface characteristics from satellite radar altimeter (RA) and Syntheitc Aperture Radar (SAR) data. The main results are an Atlas of elevation maps of Antarctica, from GEOSAT RA data and an Atlas from ERS-1 RA data, including a total of about 200 maps with 3 km grid resolution. Maps and digital terrain models are applied to monitor and study changes in Antarctic ice streams and glaciers, including Lambert Glacier/Amery Ice Shelf, Mertz and Ninnis Glaciers, Jutulstraumen Glacier, Fimbul Ice Shelf, Slessor Glacier, Williamson Glacier and others.Herzfeld, Ute C.Goddard Space Flight CenterANTARCTIC REGIONS; SURFACE ROUGHNESS; TOPOGRAPHY; SYNTHETIC APERTURE RADAR; GEOSAT SATELLITES; RADIO ALTIMETERS; SEA ICE; MATHEMATICAL MODELS; RADAR DATA; SATELLITE-BORNE RADAR; RELIEF MAPS; TERRAIN; GLACIERS...
