  • A very incomplete dataset of surface lakes in Antarctica. Data have been prepared from various map and remotely sensed datasets.

  • Complete Antarctic contour dataset, 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. Due to the differing sources, this dataset has inconsistent intervals between contour lines. The dataset has been generalised from the high resolution contour dataset in some areas. 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.

  • A very incomplete dataset of surface lakes in Antarctica. Data have been prepared from various map and remotely sensed datasets. This dataset has been generalised from the high resolution version.

  • An incomplete dataset of moraine in Antarctica. Data have been prepared from various map and remotely sensed datasets.

  • An incomplete dataset of moraine in Antarctica. Data have been prepared from various map and remotely sensed datasets.

  • A continuous contour dataset at 100 m intervals for all land south of 60degS, excluding the Balleny Islands. The vertical datum of the contours is EGM2008. Contours are extracted primarily from the PGC Reference Elevation Model of Antarctica (REMA) v1.1 with certain islands filled from Copernicus WorldDEM. Further small areas are interpreted from satellite imagery, and Peter I Oy contours are from the Norwegian Polar Institute. Sources of individual line segments are contained in the attribute table and full compilation information is given in the lineage statement. Note: contours overlap the coastline in small areas, due to resolution of the data used in creation of the lines, and potential errors in coastline and/or contour data. Certain areas are known to contain erroneous data due to faults in the original DEM data.

  • A vector polyline at 60 deg S which is the northern limit for ADD datasets.

  • An incomplete dataset of moraine in Antarctica. Data have been prepared from various map and remotely sensed datasets. This dataset has been generalised from the high resolution version but there are some inconsistencies in this dataset and the high resolution version is recommended.

  • A very incomplete dataset of streams in Antarctica. Data mainly cover Byers Peninsula, Deception Island, James Ross and Seymour islands, Fossil Bluff and some areas of the Transantarctic Mountains. Exact data sources can be found in the attribute table.
