摘要：

GIS is applied in glaciological research along the traverse route from Zhongshan Station to Dome A, one of the key routes in ITASE project, to display, process, manage and analyze the data obtained mainly by the 3rd Chinese Inland Expedition, together with Antarctic databases provided by ADD and BEDMAP project. The ways of ADD data merging and clipping, and coordinate projection transformation of field data and BEDMAP data are introduced. Elevation data derived by GPS navigator are corrected using ADD and ArcView's contour interpolation. Sub ice topography and ice thickness along the route are extracted from BEDMAP database. Slope and aspect data are derived at each positioning station. GIS is a convenient and useful tool for us to record, query and display a variety of data in detail along the traverse route.
