[GRASS-user] Re: Landsat data archive now free

[Yann Chemin]

Hi,

1 - on opening GRASS GIS, select create location from georeferenced file
2 - use r.in.gdal to import in GRASS GIS.
3 - in grass/add-ons look for any of these to correct from radiance to
reflectance at top of atmoshpere
- raster/i.landsat.toar
- gipe/i.dn2full.l5
- gipe/i.dn2full.l7

4 - use i.atcorr too correct top of atmosphere to surface reflectance.

good luck!
Yann
