Dieses Dataset stellt ein vollständiges, 15 m hohes Bildmosaik der grönländischen Eisschicht aus den SAR-Bildern Landsat 7 ETM+ und RADARSAT-1 von 1999 bis 2002 bereit. Die Methoden umfassen eine Kombination aus Bildwolkenmaskierung, Schwenkschärfe, Bildsampling und Größenänderung...
ArcticDEM ist eine öffentlich-private Initiative der National Geospatial-Intelligence Agency (NGA) und der National Science Foundation (NSF), die mithilfe von optischen Stereobildern, Hochleistungs-Computing und Open-Source-Software zur Fotogrammetrie automatisch ein hochauflösendes, hochwertiges digitales Oberflächenmodell (DSM) der Arktis erstellt. Dazu gehören Vegetation, Baumbestand, Gebäude und...

Dieses digitale Höhenmodell (DEM) besteht aus einer Kombination aus ASTER- und SPOT-5-DEMs für den Rand und Rand des Eisschildes (d. h. unterhalb der Höhe der Equilbriumlinie) südlich von etwa 82,5° N und einer AVHRR-Fotoklinometrie im Inneren des Eisschildes und weit im Norden (Betrug und ...
Dieses Dataset enthält vollständige Masken zur Klassifizierung von Landeis und Meeren in 15 m Entfernung für die grönländische Eisschicht. Die Eisbedeckung wurde mithilfe einer Kombination aus orthorektifizierten panchromatischen Bildern (Band 8) aus dem Landsat 7 Enhanced Thematic Mapper Plus (ETM+) kartiert, der vom USGS vertrieben wurde.
Dieses Dataset ist Teil des MEaSURE-Programms der NASA (Making Earth System Data Records for Use in Research Environments) und besteht aus Karten der mittleren monatlichen Geschwindigkeit für ausgewählte Gletscheraustrittsgebiete. Die Karten werden durch Nachverfolgen sichtbarer Merkmale zwischen optischen Bildpaaren generiert, die von Landsat...
