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.

ADD datasets and data access

Visit the Antarctic Digital Database map viewer to visualise the available data. Data can be downloaded through the data catalogue in GeoPackage or shapefile format.

Coastline and contour datasets are also accessible in the ArcGIS Living Atlas.

The datasets included in the ADD are:

• Coastline, including grounding lines and ice shelf fronts
• Rock outcrop
• Contours
• Lakes
• Moraine
• Streams
• Seamask
• ADD data limit at 60°S

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

A message regarding changes to the ADD WMS:

We will be retiring the current Web Map Services (WMS) for the ADD effective November 12th 2024.

This will affect all WMS layers currently accessed via the endpoint https://maps.bas.ac.uk/antarctic/wms.

We are publishing replacement services through the Esri Living Atlas of the World, which will be updated with any future data releases. These are available in variety of protocols including (OGC) WMTS and OGC API Features, as well as Esri feature and vector tile services.

Please see https://www.arcgis.com/home/group.html?id=307a4d4221ca4030aef7477d6a52620f for currently available layers.

We encourage all users to switch to these replacement services by the 12th November.

We will leave these services running until 12th May 2025, supported on a best efforts basis. They may stop working before this end date if needed for operational reasons. They will not be updated with any further data changes.

If you require information or assistance related to ADD web services, please contact magic@bas.ac.uk

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 November 2024 – version 7.10.

Planned releases and data updates:

• 12th May 2025

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.
