Description
Conversion to TOA reflectance of satellite data.
Usage
reflconv(x, Mp, Ap)
Arguments
x |
Image to be converted, in matrix, data frame, or SpatialGridDataFrame format.
|
Mp |
Band specific multiplicative rescaling factor from the metadata (MTL file) (REFLECTANCE_MULT_BAND_x, where x is the band number).
|
Ap |
Band specific additive rescaling factor from the metadata (MTL file) (REFLECTANCE_ADD_BAND_x, where x is the band number).
