Re: [GRASS-dev] compile 6S library in GRASS

Hi, I would like to second Markus on that one. We considered using AERONET for atmospheric correction in i.atcorr, but ended up using arbitrary / averaged values, cause AERONET data for our locations was very, very sparse and showed very high variation. So, in a module, that compiles a 6s-para

Re: [GRASS-dev] compile 6S library in GRASS

Obviously the module will be implemented with various options (manual balie, AREONET, etc.) Concerning AREONET effectively the Py6S library do only an "interpolation" searching the closest time and wave length, so Roberta are writing the routine without using py6s. Thanks all' for the suggestions

a wild guess: specify a raster input option for AOT (alongside other options), let user find its image source and use it. Very limited requirement for the GSoC student, most latitude for the the modules user. -- Dr. Yann Chemin Freelancer +33 7 83 85 5234 3 Toulmelin, 56400 Plumergat, FR

Re: [GRASS-dev] compile 6S library in GRASS

Just one quick follow up question regarding your wild guess: With a raster map option, the module would have to make assumptions on units / scale of values in the map (documented in the manual), so in the further process e.g. average or median could be extracted (r.univar) and fed to 6s input f

Re: [GRASS-dev] compile 6S library in GRASS

Thanks for clarification, Markus. So, what would a module that puts together an 6s input file (which is what Roberta is about to produce if I understood correctly) have to do with a visibility map then? Nothing, probably? Would visibility values in the 6s parameter file be overwritten if a AOD

Moritz, I don't know why but today I have some trouble with your email, I receive them after some hours...anyway I read the last from the dev digest. Regarding AERONET data, it's not possible to completely automate the procedure (search for the proper file, download, unzip, read and so on..), I ha
