Scientific work in Antarctica and its operational support depends on a reliable, consistent geographic framework. The SCAR Antarctic Digital Database (ADD) (http://www.scar.org/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 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.
