Low resolution vector contours for Antarctica

Complete Antarctic contour dataset at 1000 m intervals, split and labelled according to whether the contour represents an ice or rock surface. Data have been prepared from various map and remotely sensed datasets. This dataset has been generalised from the high resolution contour dataset. Further information regarding source and source data can be found within the high resolution attribute table. Certain inconsistencies and errors are currently known and a comprehensive update is planned for version 7.3.
