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.

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.
