reflconvS: Conversion to TOA Reflectance with a Correction for the Sun...

In landsat8: Landsat 8 Imagery Rescaled to Reflectance, Radiance and/or Temperature

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.
