The SCAR Antarctic Digital Database (ADD) is a seamless compilation of topographic data for Antarctica to 60°S. The ADD is the place to view, query and download topographic datasets such as the Antarctic coastline, contours and rock outcrop.
British Antarctic Survey (BAS) compiles, manages and distributes the ADD datasets on behalf of SCAGI, the SCAR Standing Committee on Geographic Information.
