Antarctic Digital Database
The Antarctic Digital database (ADD) is a compilation of medium scale topographic data for the continent of en:Antarctica. It is derived from a wide variety of sources, and aims to provide the best currently available data in all areas. However, users should note that the resolution of the data varies widely. The most detailed information is taken from maps compiled at a scale of 1:50,000 (i.e. a resolution of approximately 25 m); the least detailed from sources with a resolution of at best 5 km. The lowest resolution data are, however, from the great ice sheets where the relief is very low, and where higher resolution data would not be useful.
