LANDSAT Pre-Processing

Some notes from Yann Chemin:

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