ArcticDEM est une initiative publique et privée de la National Geospatial-Intelligence Agency (NGA) et de la National Science Foundation (NSF) visant à produire automatiquement un modèle de surface numérique (DSM) haute résolution et de haute qualité de l'Arctique à l'aide d'images stéréo optiques, de calculs hautes performances et d'un logiciel de photogrammétrie Open Source. Il s'agit de la végétation, du couvert forestier, des bâtiments et...

Le modèle d'élévation de référence de l'Antarctique (REMA) est un modèle numérique de surface de l'Antarctique, horodaté et haute résolution, à des résolutions spatiales de 2 et 8 mètres. Les fichiers DEM imbriqués sont compilés à partir de plusieurs bandes qui ont été co-enregistrées, mélangées et plumes afin de réduire les artefacts de mise en correspondance des bords.
