[GRASS-dev] MODIS Metadata information kept after GDALimport/warp into GRASS

[António Rocha]

Those hist files only include the operations that are performed inside 
GRASS. But for instance, MERIS-ENVISAT and other EO data includes GAIN, 
SCALEFACTOR and other parameter that are relevant for image processing. 
When I import them to GRASS how can I maintain this information in 
raster header?
Or isn't possible and I only can do that, by inserting text using 
r.support, when images are already imported to GRASS?

Thank you Hamish
