[GRASS-user] Feedback upon Landsat related modules

[Nikos Alexandris]

Dear GRASS-GIS developers and users,

I just want to share my satisfaction using the following (all?) Landsat 
related modules available in GRASS-GIS, both core and AddOns:

i.landsat.trim, i.landsat.toar, i.landsat.dehaze or i.atcorr, i.landsat.acca, 
i.topo.corr , i.landsat.rgb


All in all,  given a proper handling, the modules do their job and they do it 
well with Landsat5TM imagery. Only a few comments out of a quick, mainly 
visual, assessment.

i.landsat.trim -- it might be that it won't work as expected sometimes, 
requires experimenting with the buffer? This is known.

i.atcorr -- requires some homework but it does it's job. It would be great *if 
possible* to have done most of the metadata-retrieving work automatically for 
all bands of a scene. In case it fails, force the user to do it manually.

Thank you to all people worked hard to get these modules in GRASS-GIS, Nikos
