摘要: This study evaluates the radiometric consistency between Landsat-8 Operational Land Imager (OLI) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) using cross calibration techniques. Two approaches are used, one based on two sensors simultaneous image pairs, acquired during an underfly event 29–30 March 2013. The other approach is time series of statistics by these over Libya 4 pseudo invariant site (PICS) (+28.55°N, +23.39°E). Analyses from show that reflectance OLI generally within ±3% ETM+ radiance for all reflective bands visible to short wave infrared regions when ChKur solar spectrum used convert reflectance. Similar results obtained comparing directly with in different physical units (radiance reflectance) agree ±2% analogous bands. These will also be useful tie heritage 1 MultiSpectral Scanner (MSS) through a consistent scale.
