Antarctic Digital Database

Antarctic Digital Database

The Scientific Committee on Antarctic Research (SCAR) ADD is a seamless compilation of topographic data for Antarctica to 60°S. The ADD is the place to view, query and download datasets such as the Antarctic coastline, contours and rock outcrop.

The Mapping and Geographic Information Centre (MAGIC) compiles, manages and distributes the ADD datasets on behalf of SCAGI, the SCAR Standing Committee on Geographic Information.

  • Contours
  • Lakes
  • Moraine
  • Streams
  • Seamask
  • ADD data limit at 60°S

All datasets are in WGS84 Antarctic Polar Stereographic projection, EPSG 3031.

Data update schedule

Datasets within the ADD are reviewed on a regular basis, and updated accordingly. Any changes to datasets are released as new versions every 6 months. Where a dataset is not updated within this schedule, the most recent dataset will continue to be used.

Last release: 12th May 2021- version 7.4

Further details of the last release can be found on the ADD blog.

Planned releases and data updates:

  • 12th November 2021 – None
  • 12th May 2022 – Updates planned to coastline datasets to reflect recent changes to ice shelf fronts. Other dataset updates will be considered in early 2022.

Contributing to the ADD

The ADD is a service to the whole Antarctic science and logistics community, and as such we invite all users of the data to be active participants in improving its quality.   Any inconsistencies can be reported via the web interface (the feedback button in the top navigation bar), or to the Mapping and Geographic Information Centre. Similarly, any new or updated data from users are welcome for potential future inclusion in the ADD. Please also contact us if you have any questions about the ADD generally.
