radconv: Conversion to TOA Radiance

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

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)).
