R: Conversion to TOA Radiance
Conversion to TOA Radiance
Description
Conversion to TOA radiance of satellite data.
Usage
radconv(x, Ml, Al)
Arguments
x |
Image to be converted, in matrix, data frame, or SpatialGridDataFrame format.
|
Ml |
band specific multiplicative rescaling factor from the metadata (MTL file) (RADIANCE_MULT_BAND_x, where x is the band number).
|
Al |
Mp band specific additive rescaling factor from the metadata (MTL file) (RADIANCE_ADD_BAND_x, where x is the band number).
|
Value
TOA spectral radiance (Watts/(m2*srad*micro-m)).
