[GRASS-dev] ASTER radiance, top-of-atmosphere reflectance and temperature

Carlos_Guano_Grohman · March 17, 2016, 1:32am

Hi all,

A couple of weeks ago I was having problems with i.aster.toar [1]. after Nikos’ input with his bash script for calculation radiance and reflectance for ASTER images, I made a python version that calculates radiance, reflectance (VNIR/SWIR) and temperature (TIR). Output of temperature can be in Kelvin, Celsius or Fahrenheit.

The user can process all bands (‘all’), pre-defined subsets (vnir, swir, vnswir, tir) or a choice of bands.

Radiance is calculated by default, while reflectance and temperature are optional.

I’d appreciate if anyone could test it.

best

Carlos
