I'm facing an issue when running i.landsat.toar with a Landsat 7 image, here's the list of files:

  • LE70010752014040CUB00_B1
  • LE70010752014040CUB00_B2
  • LE70010752014040CUB00_B3
  • LE70010752014040CUB00_B4
  • LE70010752014040CUB00_B5
  • LE70010752014040CUB00_B6_VCID_1
  • LE70010752014040CUB00_B6_VCID_2
  • LE70010752014040CUB00_B7
  • LE70010752014040CUB00_B8

When the command is processing the bands, it gets stuck in band 6 and gives this error message:

ERROR: Unable to open header file for raster map <LE70010752014040CUB00_B61@>.

The rest of the band (7 and 8) aren't processed, neither with reflectance or radiance selected.

I configured the input_prefix=LE70010752014040CUB00_B and output_prefix=reflectance_

    band6 is for temperature, did you configured the output? – Pau Feb 4 '15 at 15:03
  • yes, with output_prefix=reflectance_ – aldeano Feb 4 '15 at 20:02
  • When you work with temperature you don´t use reflectance. use output_prefix=_toar (I read the grass documentation and it doesn´t include a parameter to TOA temperature). Also you can try changing the name of the band from "LE70010752014040CUB00_B6_VCID_1" to "LE70010752014040CUB00_B61". Landsat 7 have to ways to name the band 6 (with and without VCID), but change the metadata of the file too. – Pau Feb 5 '15 at 12:10
  • I don't need the reflectance of the band 6, my problem is that grass stops working with the rest of the bands, and i need the reflectance of bands 7 and 8. – aldeano Feb 5 '15 at 13:48

It's no so elegant, but renaming LE70010752014040CUB00_B6_VCID_1 to LE70010752014040CUB00_B61 do the trick. If there's a way i can do this with patterns it'll be better.

Please remove temperature bands (LE70010752014040CUB00_B6_VCID_1 & LE70010752014040CUB00_B6_VCID_2) from folder. Then grass will process 7 and 8 bands too.
