Rauer Group 1:50000 Topographic GIS dataset. Data conforms to SCAR Feature Catalogue which can be searched (refer to link below). 10 metre contour interval on rock, 20 metre contour interval on ice up to 100 metres, 100 metre contour interval on ice above 100 metres.
Owing to the surface conditions at the time of the photography small islands and lakes may not be present and the shapes of features may be incorrect. The topographic data covering the island group and coastal region has been sourced from ANARE aerial photography dated 1960 (films ANT97 and ANT75). Contours on ice where sourced from 1:100,000 and 1:200,000 scale Soviet mapping. SPOT XS satellite ... imagery (K281-J493 of 16/2/90) was used to define the seaward extent of glacier tongues. Owing to deficiencies in the aerial photography (no camera calibration or fiducial marks and insufficient overlays) and lack of ground control these data do not meet 1:50,000 mapping standards. Distortions of up to 50 metres are known to exist in the data. Note: The link to shapefile below links to all Rauer Group GIS data. This record refers specially to data with a dataset_id = 75.
