Landsat 8 Collection 2 Tier 1 und Echtzeitdaten mit kalibrierter Reflexion an der Atmosphärengrenze (Top-of-Atmosphere, TOA). Die Kalibrierungsfaktoren werden aus den Bildmetadaten extrahiert. Weitere Informationen zur Berechnung der TOA finden Sie in Chander et al. (2009). Landsat-Szenen mit der höchsten verfügbaren Datenqualität werden in Stufe 1 eingestuft…
DN-Werte der Landsat 8-Sammlung 2, Stufe 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 …
