Mosaico della Groenlandia - 2000 - Ice Mapping Project (GIMP) della Groenlandia
Questo set di dati fornisce un mosaico di immagini con risoluzione completa di 15 m della calotta glaciale della Groenlandia derivata dalle immagini SAR di Landsat 7 ETM+ e RADARSAT-1 degli anni dal 1999 al 2002. I metodi includono una combinazione di mascheramento delle nuvole delle immagini, aumento della nitidezza delle immagini, campionamento e ridimensionamento delle immagini... artico gimp greenland immagini nasa polare -
Mosaico ArcticDEM v4.1
ArcticDEM è un'iniziativa pubblica/privata della National Geospatial-Intelligence Agency (NGA) e della National Science Foundation (NSF) per produrre automaticamente un modello di superficie digitale (DSM) ad alta risoluzione e di alta qualità dell'Artico mediante immagini stereoscopiche ottiche, computing ad alte prestazioni e software di fotogrammetria open source.

Groenlandia DEM - Greenland Mapping Project (GIMP)
Questo Digital Elevation Model (DEM) è realizzato a partire da una combinazione di DEM ASTER e SPOT-5 per la periferia e il margine della calotta glaciale (ovvero al di sotto dell'elevazione della linea dell'equilbrium) a sud di circa 82,5°N e la fotoclimetria AVHRR all'interno e all'estremo nord (Scambos e ... artico elevazione-topografia gimp groenlandia nasa polare -
Maschera di ghiaccio e oceano in Groenlandia - Greenland Mapping Project (GIMP)
Questo set di dati fornisce maschere complete di classificazione della banchisa e dell'oceano a 15 m per la calotta glaciale della Groenlandia. La copertura ghiacciata è stata mappata utilizzando una combinazione di immagini pancromatiche ortorettificate (banda 8) del Landsat 7 Advanced Thematic Mapper Plus (ETM+), distribuito dall'USGS e ... artico criosfera gimp groenlandia ghiaccio nasa -
MISURE la velocità del ghiaccio in Groenlandia: mappe di velocità del sito dei ghiacciai selezionate da immagini ottiche, versione 2
Questo set di dati, parte del programma NASA Making Earth System Data Record for Use in Research Environments (MEaSUREs), è costituito da mappe della velocità media mensili per le aree di sbocco dei ghiacciai. Le mappe sono generate monitorando gli elementi visibili tra coppie ottiche di immagini acquisite da Landsat... artico criosfera gimp groenlandia ghiaccio nasa
