O Modelo de elevação de referência da Antártica (REMA, na sigla em inglês) é um modelo digital de superfície (DSM, na sigla em inglês) de alta resolução e com carimbo de data/hora da Antártica em resoluções espaciais de 2 e 8 metros.
Os arquivos DEM em mosaico são compilados de várias faixas que foram registradas, combinadas e suavizadas para reduzir artefatos de correspondência de borda.
