Conversion to TOA Reflectance with a Correction for the Sun Angle

Description

Conversion to TOA reflectance with a correction for the sun angle of satellite data.

Usage

reflconvS(x, Mp, Ap, sunelev)

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).

sunelev

Sun elevation in degrees is provided in the metadata (MTL file) (SUN_ELEVATION).

Value

TOA spectral radiance with a correction for the sun angle.
