Der Datensatz GLS2005 umfasst 9.500 orthorektifizierte Satellitenbilder mit mittlerer Auflösung, die zwischen 2004 und 2007 aufgenommen wurden und die Landmassen der Erde abdecken. GLS2005 verwendet hauptsächlich Landsat 5- und Lücken geschlossene Landsat 7-Daten mit EO-1 ALI- und Terra ASTER-Daten, um Lücken zu schließen.

DN-Werte der Landsat 7 Collection 2 Tier 2, die die skalierte, kalibrierte Leuchtkraft am Sensor darstellen. Szenen, die während der Verarbeitung nicht die Kriterien für Tier 1 erfüllen, werden Tier 2 zugeordnet. Dazu gehören Szenen mit systematischem Gelände (L1GT) und systematischen (L1GS) Verarbeitungen sowie alle L1TP-Szenen, die nicht …
Dieser Datensatz enthält atmosphärisch korrigierte Oberflächenreflexionen und Bodenoberflächentemperaturen, die aus den Daten des Landsat 7 ETM+-Sensors abgeleitet wurden. Diese Bilder enthalten vier Bänder im sichtbaren und nahen Infrarot (VNIR) und zwei Bänder im kurzwelligen Infrarot (SWIR), die zu einer orthorectifizierten Oberflächenreflexion verarbeitet wurden, sowie ein thermisches …
