Determination of planetary reflectance for Landsat-5 Thematic-Mapper tapes processed by Earthnet (Italy)
Abstract
A method is described by which Landsat Thematic-Mapper (TM) data from tapes that have been radiometrically correlated based on preflight data by Earthnet (Italy) can be converted for use in the determination of planetary reflectance. It is shown that, depending on the TM band concerned, a correct gain factor gives a 1 to 20 percent higher estimation of planetary reflectance (at the satellite) than use of the original data on these tapes. In addition, correct use of bandwidths gives a 4 to 14 percent higher planetary reflectance value.
