[GRASS-user] Re: i.atcorr returns all NULL values

[Chemin, Yann (IWMI)]

Can you please share your scripts (both i.landsat.toar and i.atcorr)
please.
Also can you share the .met or _MTL.txt that came with your failing
Landsat image.
Finally, the r.info output for one of the band that is failing in
i.atcorr.

Thank you,
Yann

I have the same problem, both with band 1 and 2.
I did i.landsat.toar and then i.atcorr but all the bands worked except
for band 1 and 2, these have values min=-nan and max=-nan.
There is someone who can help us?

Thank you!
Elena
