In satellite: Handling and Manipulating Remote Sensing Data

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.

Details

The conversion functions are taken from USGS' Landsat 8 Data Users Handbook which is available online at https://www.usgs.gov/landsat-missions/landsat-8-data-users-handbook.

Value

raster::Raster* object with converted values.
