Description

Conversion to TOA radiance of satellite data.

Usage

1
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)).
