The Ross Sea Region covers the sector of Antarctica between 160° East, 150° West and 60° South. The Ross Sea Region Geodetic Datum 2000 (RSRGD2000) is the official geodetic datum for this area. To facilitate the consistent topographic mapping and integration of spatial datasets a series of map projections has been defined.
More information about the development of the projections is available in the document Background to Ross Sea Region Projections.
The Ross Sea Region projections are formally defined in LINZS25008 Standard for Ross Sea Region Geodetic Datum 2000 Projections. The key parameters for each projection are listed in the tables below:
