convRef2RadLinear: Convert reflectance to radiance using linear function coefficients

Description

The function converts the reflectance (ref) back to radiance (rad) given that linear conversion coefficients for both radiance and reflectance are available.

Usage

convRef2RadLinear(band, refm, refa, radm, rada, szen)

Arguments

band
raster::RasterStack or raster::RasterLayer containing reflectance.
refm
Multiplication coefficient for reflectance conversion.
refa
Addtition coefficient for reflectance conversion.
radm
Multiplication coefficient for radiance conversion.
rada
Addition coefficient for radiance conversion.
szen
Sun zenith angle.

Value

  • raster::Raster* object with converted values.

Details

The conversion functions are taken from USGS' Landsat 8 manual which is available online at http://landsat.usgs.gov/Landsat8_Using_Product.php.
