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.

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 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.

Topographic contours of Signy Island with 10 m intervals, derived from a digital elevation model originally created using stereoscopic photogrammetry from VHR (very high resolution) In-Track stereo satellite imagery collected during March 2015. The topographic contours were created to support the updated release of the British Antarctic Survey (BAS) Signy Island map (BAS, 2024). The dataset is available as a polyline shapefile and a GeoPackage. WorldView-3 satellite images (c) 2015 Maxar Technologies.

The first edition of the Antarctic Digital Database (ADD) coastline polyline dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Line dataset was originally published on CD-ROM in 1993, in tiled Coverage format. Data has since been converted merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced. The ADD project was first proposed in 1990 by a Cambridge (UK) based consortium comprising British Antarctic Survey (BAS), Scott Polar Research Institute (SPRI) and the World Conservation Monitoring Centre (now UNEP World Conservation Monitoring Centre (UNEP-WCMC)). International participation in the project was agreed through the Scientific Committee on Antarctic Research (SCAR) and its Working Group on Geodesy and Geographic Information. The majority of data capture data management was undertaken in Cambridge, UK. Work was initially funded by BAS and by The British Petroleum Company p.l.c (BP). Other contributing nations sponsored their own data capture through either their national mapping agencies or their Antarctic research organisations. BP had no commercial interest in the project and the information gained from this database was in the public domain. BAS, SPRI, WCMC and SCAR, by entering into this project with BP, in no way implied their acceptance or endorsement of any exploration activity for oil, gas or minerals in Antarctica. For full details on the dataset, please refer to the ADD Manual v1.0: https://nora.nerc.ac.uk/id/eprint/517623/.

The first edition of the Antarctic Digital Database (ADD) coastline polygon dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Polygon dataset was originally published on CD-ROM in 1993, in tiled Coverage format. Data has since been converted and merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced. Each polygon has a surface attribute (CST00SRF) indicating the type of feature it represents, ie. ice shelf, ice tongue, land, ocean and rumple. For information on source of polygon delineations, refer to coincident features in the polyline dataset, Scale0 vector polylines of the Antarctic coastline v1.0.

The second edition of the Antarctic Digital Database (ADD) coastline polygon dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Polygon dataset was originally published on CD-ROM in 1998, in tiled Coverage format. Data has since been converted and merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced. Each polygon has a surface attribute (CST00SRF) indicating the type of feature it represents, ie. ice shelf, ice tongue, land, ocean and rumple. For information on the source of polygon delineations, refer to coincident features in the polyline dataset, Scale0 vector polylines of the Antarctic coastline v2.0. ADD Version 2.0 contained many amendments to the original data. Most corrections were made in Quadrant 4, which covers the Antarctic Peninsula, parts of Ellsworth Land and Coats Land. A few features, such as Doake Ice Rumples, were inadvertently omitted from ADD Version 1.0, so were included in this version for the first time. Data for the Ronne and Filchner ice shelves were also upgraded. A new map of James Ross Island was incorporated, and the positions of ice fronts of the northern Larsen Ice Shelf, Wordie Ice Shelf and Wilkins Ice Shelf were also amended using the latest available information. Other minor changes were also made and documented in the ADD Manual: https://nora.nerc.ac.uk/id/eprint/536533/. The UK Consortium behind the ADD Version 1.0 passed the ongoing maintenance and revision of the ADD to British Antarctic Survey (BAS) for Version 2.0.

Covering all land and ice shelves south of 60S. 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. Major changes in v7.5 include updates to ice shelf fronts in the following regions: Seal Nunataks and Scar Inlet region, the Ronne-Filchner Ice Shelf, between the Brunt Ice Shelf and Riiser-Larsen Peninsula, the Shackleton and Conger ice shelves, and Crosson, Thwaites and Pine Island. Small areas of grounding line and ice coastlines were also updated in some of these regions as needed.
