[GRASS-user] bug with r.reclass

Dear All:

I am trying to use the grass i.atcor for atmospheric correcction. Would you give me a clue what the ‘‘text file’’ to be used asone of the input parameters and if possible the sample/format of the file. The dialogue window for input image does not seem to allow uploading the raster file. Any assistance is very much appreciated.

Best regards,

Asefa

Dear all,

I’m facing a problem with r.reclass on GRASS 6.4.2 on Linux mint.

r.reclass seems to have a small bug.
I worked with output name “test” , but then, It didn’t work any more with others output names…
This the command I did:
r.reclass --overwrite input=input@mapset output=test rules=path
With the rules:
3 thru 7 = 1

  • = NUll

I received the following error when I tried to display the raster or to see the metadata (In french, sorry!):
It says that it is not possible to find the history of the file and to read the boundary file (or limit file)

Do someone has an idea what the problem is ?

Dear Asefa,

please use a proper subject title when mailing to the list -- otherwise, your
mail might get "lost" and maybe not read at all.

Besides the manual of i.atcorr itself
<http://grass.osgeo.org/grass64/manuals/i.atcorr.html&gt;, you might want to have
a look in the respecti GRASS wiki page (and section)
<http://grasswiki.osgeo.org/wiki/Atmospheric_correction#Atmospheric_correction&gt;\.

This two sources should help.

Best, Nikos
