An incomplete dataset of moraine 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. Certain regions contain very detailed contours obtained from VHR elevation models and photogrammetry work. Further information regarding source and source data can be found within the attribute table. Certain inconsistencies and errors are currently known and a comprehensive update is planned for version 7.3.

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 continuous, smoothed contour dataset at 500 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. 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.

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.

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 new version of this dataset exists. To see the last version of the Antarctic Digital Database, have a look here: https://data.bas.ac.uk/collections/e74543c0-4c4e-4b41-aa33-5bb2f67df389/ A high resolution seamask for regions south of 60S, comprised of a roundel polygon with all land and ice shelves erased. High resolution versions of ADD data are suitable for scales larger than 1:1,000,000. The largest suitable scale is changeable and dependent on the region. Data compiled, managed and distributed by the Mapping and Geographic Information Centre and the UK Polar Data Centre, British Antarctic Survey on behalf of the Scientific Committee on Antarctic Research.

Coastline for Antarctica created from various mapping and remote sensing sources, provided as polygons with ''land'', ''ice shelf'', ''ice tongue'' or ''rumple'' attribute. Covering all land and ice shelves south of 60degS. Suitable for topographic mapping and analysis. High resolution versions of ADD data are suitable for scales larger than 1:1,000,000. The largest suitable scale is changeable and dependent on the region. Changes in v7.8 include updates to the Brunt, Wilkins and Stange Ice Shelves, Pine Island and Thwaites Glaciers and James Ross Island ice fronts.
