[GRASS-user] problem with i.landsat.toar

GRASS GRASS user

Dear All,

I have been working on landsat 8 in GRASS 7 for a while now. I had used uncorrected method in i.landsat.toar so far and had not faced any problems in converting DN values for bands 1 to 7. However, this time I tried using DOS1 algorithm and it didn’t work. It shows an error something like

“could not find header for LC8…_B8@”.

I tried to understand metafile but could not detect anything. Can someone help me with this.

Thanking you,

Regards

I recently processed some Landsat8 data with a fresh GRASS 7.0.svn, it
worked ok.
Do you still face problems?
