Mosaïque du Groenland 2000 - Projet de cartographie des glaces du Groenland (GIMP)
Cet ensemble de données fournit une mosaïque d'images complètes (résolution de 15 mètres) de la calotte glaciaire du Groenland, dérivée des images satellite Landsat 7 ETM+ et RADARSAT-1 réalisées entre 1999 et 2002. Ces méthodes combinent le masquage des nuages d'images, l'amélioration de la netteté, l'échantillonnage et le redimensionnement des images, etc. Arctique Gimp Groenland Imagerie Nasa Polaire -
ArcticDEM Mosaic V4.1
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... arctique dem élévation-topographie géophysique pgc umn -

DEM du Groenland – Projet de cartographie du Groenland (GIMP)
Ce modèle numérique d'altitude (DEM, Digital Elevation Model) est construit à partir d'une combinaison de DEM ASTER et SPOT-5 pour la périphérie et la marge de la nappe glaciaire (c'est-à-dire sous l'élévation de la ligne d'équilibre) au sud d'environ 82,5 °N et la photoclinométrie AVHRR à l'intérieur et à l'extrême nord (Scambos et...

Masque de glace et d'océan du Groenland – Projet de cartographie du Groenland (GIMP)
Cet ensemble de données fournit des masques complets de classification des glaces terrestres et océaniques à 15 m de la calotte glaciaire du Groenland. La couverture glaciaire a été cartographiée à l'aide d'une combinaison d'images panchromatiques orthorectifiées (bande 8) de l'outil Landsat 7 Enhanced Thematic Mapper Plus (ETM+), distribuée par l'USGS, et...
