Run printenv from your console and from the cron then compare the output

I often find myself trying to accomplish a similar task. I find it suits my

Or maybe you could use the r.patch command to combine them into one raster
with one colortable.

Hi Rich,
I've had this problem before and for me it always seemed to be an issue of
setting the size of labels correctly, which can be tricky sometimes,
particularly if your location is latlong (if I remember correctly the size
is in map units, so in that case you need to compute your desired labe
Hi Tanya,
Try this in the command line:
r.mapcalc "newmap = 741.0 * 0.01"
or in the GUI use the map calculator and put in your desired equation as
above.
The output of this command will be a new map with a value of 7.41. You can
read about the mapcalc command here:

Hi Janet,
Do you mean you want to create contour lines at 30m intervals? If so,
r.contour would do the trick.

I think that means to start grass, such as type "grass" into your command
line and then go through the steps to select your location so as to start a
grass session.

Hi Gergely,
I do a lot of predictive modeling, and the approach I take is to export my
data (prepared in GRASS GIS) to an open-source modeling software such WEKA,
and then map the results using GRASS. It takes a little more work than
utilizing built in modeling options often found in GIS software,
Dear All,
Thanks for all the help on this matter. Sorry for the late reply (fieldwork

I ended up solving the problem by (1) filling the ocean nulls, (2)
splitting the region into subregions, and (3) running it on a more powerful
machine.

You can give each map the color table from one particular map and then it
will be comparable across maps. You'll need to make sure you give it the

You could use r.mapcalc and make all negs = -1, all pos = 1, leave all 0 = 0.
Then make a color table where -1 is blue, 0 is green and 1 is red. I'm doing
the very same thing right now :-)
