Some notes from Yann Chemin:

Open GRASS GIS, select create location from georeferenced file
Use r.in.gdal to import into GRASS GIS.
In grass/add-ons look for any of these to correct from radiance to reflectance at top of atmosphere
1. i.landsat.toar
2. i.dn2full.l5
3. i.dn2full.l7
Use i.atcorr too correct top of atmosphere to surface reflectance
