Product ADDScientific work in Antarctica and its operational support depends on a reliable, consistent geographic framework. The SCAR Antarctic Digital Database (ADD) aims to provide a seamless topographic map compiled from the best available international geographic information for all areas. It covers Antarctica south of 60°S.

The SCAR ADD consists of geographic information layers including coastline, ice-shelf grounding line, rock outcrop, contours, elevation point data such as survey points and spot heights, and human-presence features such as Research Station locations. It also includes other relevant information sources such as the Landsat Image Mosaic of Antarctica (LIMA), bedrock and surface Digital Elevation Models from BEDMAP, and glacier and ice-shelf change information for some regions.

The data are available through the ADD website in a range of formats including shapefile, KML and Geotiff. The ADD is available free for scientific, operational and non-profit use but may not be used in commercial products without permission from SCAR.

The ADD website is a compilation of the best available geographic information for all areas. Consequently resolution varies from area to area according to the resolution of the source data. A few areas are based on maps compiled at scales of 1:50,000 scale or larger. Most mountainous areas such as the Antarctic Peninsula and TransAntarctic Mountains rely on mapping at 1:250,000 scale. The coastline and elevation information for the interior of the continent are based on remote-sensing data. All information served by the website has metadata stating the source.

pdf The manual of version 3.0 of the Antarctic Digital Database (July 2000) (2.55 MB) is available through the SCAR Library.
