USGS Landsat 8 Collection 2 Tier 1 Raw Scenes
Valori DN di Landsat 8 Collection 2 Tier 1, che rappresentano la radianza al sensore calibrata e scalata. Le scene Landsat con la qualità dei dati più elevata disponibile sono inserite nel livello 1 e sono considerate adatte per l'analisi dell'elaborazione delle serie temporali. Il livello 1 include i dati elaborati del livello 1 di precisione del terreno (L1TP) che hanno … c2 global l8 landsat lc8 oli-tirs -
