Hi Micha. After i.landsat.toar you will have either Radiance or Reflectance. For both the 11-bit range suggested above is not valid I think. In the metadata file the minimum and maximum values for spectral radiance are reported (watts / m^2 * ster * microns). As for the reflectance, it is unitless and should, in theory, range in [0, 1.0]. Though, outliers are sometimes expected. Nikos _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
