Le modèle d'altitude de référence de l'Antarctique (REMA, Reference Elevation Model of Antarctica) est un modèle numérique de surface (DSM, Digital Surface Model) haute résolution et horodaté de l'Antarctique, avec des résolutions spatiales de 2 et 8 mètres.
Les fichiers DEM mosaïqués sont compilés à partir de plusieurs bandes qui ont été corégistrées, fusionnées et adoucies pour réduire les artefacts de correspondance des bords.
