Regarding i.atcorr I thought that the only thing i.atcorr perfoms is the

I do have installed. I'm running in Ubuntu and with xterm version 243.
Is it required other packages such as xtermcontrol or xtermset? Or more
packages? or in the ./configure

Regarding this... According to Lillesand and Kiefer the idea is to correct
geometric distortions of the image.
For instance, the Georrectify module is no

I have a bunch of points (4+ million) with one outlier that needs

a vector points file and associated table in sqlite.

In GRASS 6.3 there was an output vector map option "outwalk" for
walkers in r.sim.water.
http://grass.itc.it/grass63/manuals/html63_user/r.sim.water.html
In GRASS 6.4 and 6.5, that output option seems to have gone away.

hi all, I need some help with a script I'm doing if it's not possible to
order the attributes of a road network in matrix form as having ordered the

just stick it somewhere in the %PATH%.
perhaps in %GISBASE%\bin\ with all the modules, where %GISBASE% is
wherever grass is installed to (perhaps C:\GRASS\).

perhaps use r.mapcalc or r.reclass to filter out the bad point?
r.mapcalc "clean = if(map > 99, null(), map)"
or
r.reclass
99 thru 999 = NULL
* = *
and finally "r.null setnull=bad_value" may
26 matches
