Mosaïque du Groenland 2000 – Greenland Ice Mapping Project (GIMP)
Cet ensemble de données fournit une mosaïque d'images complète de la calotte glaciaire du Groenland, à une résolution de 15 m, dérivée des images ETM+ de Landsat 7 et des images SAR de RADARSAT-1 de 1999 à 2002. Ces méthodes combinent le masquage des nuages, l'accentuation du panoramique, l'échantillonnage et le redimensionnement des images, etc. arctique gimp groenland imagerie nasa polaire -
Modèle numérique de terrain de 1 km de résolution de CryoSat-2 en Antarctique
Cet ensemble de données est un modèle numérique d'élévation (MNE) de la calotte glaciaire et des plates-formes glaciaires de l'Antarctique, basé sur les observations enregistrées par l'altimètre radar du satellite CryoSat-2 entre juillet 2010 et juillet 2016. Le DEM est constitué d'ajustements spatio-temporels des mesures d'élévation cumulées sur une période de 1 … antarctica dem elevation elevation-topography polar -
DEM du Groenland : Greenland Mapping Project (GIMP)
Ce modèle numérique d'élévation (DEM) est construit à partir d'une combinaison de DEM ASTER et SPOT-5 pour la périphérie et la marge de la calotte glaciaire (c'est-à-dire en dessous de l'altitude de la ligne d'équilibre) au sud d'environ 82,5° N et de la photoclinométrie AVHRR à l'intérieur de la calotte glaciaire et dans l'extrême nord (Scambos et … arctic elevation-topography gimp greenland nasa polar -
Masque de glace et d'océan du Groenland – Greenland Mapping Project (GIMP)
Ce jeu de données fournit des masques de classification complets pour la glace terrestre et l'océan à 15 m pour la calotte glaciaire du Groenland. La couverture de glace a été cartographiée à l'aide d'une combinaison d'images panchromatiques orthorectifiées (bande 8) du ETM+ (Enhanced Thematic Mapper Plus) du satellite Landsat 7, distribuées par l'USGS, et … arctique cryosphère gimp groenland glace nasa -
MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images Version 2
Cet ensemble de données, qui fait partie du programme MEaSUREs (Making Earth System Data Records for Use in Research Environments) de la NASA, se compose de cartes de la vitesse moyenne mensuelle pour certaines zones de sortie de glaciers. Les cartes sont générées en suivant les éléments visibles entre les paires d'images optiques acquises par le satellite Landsat. arctique cryosphère gimp groenland glace nasa
