convRef2RadLinear

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

Herein, we provide a broad variety of functions which are useful
for handling, manipulating, and visualizing satellite-based remote sensing
data. These operations range from mere data import and layer handling (eg
subsetting), over Raster* typical data wrangling (eg crop, extend), to more
sophisticated (pre-)processing tasks typically applied to satellite imagery
(eg atmospheric and topographic correction). This functionality is
complemented by a full access to the satellite layers' metadata at any
stage and the documentation of performed actions in a separate log file.
Currently available sensors include Landsat 4-5 (TM), 7 (ETM+), and 8
(OLI/TIRS Combined), and additional compatibility is ensured for the Landsat
Global Land Survey data set.
