Thank you so much, Markus!
That was the missing hint and it works now!
However, I just went through the documentation, which says: "/F/ means
that the functions always results in a floating point value" and
Function "log" has "F".
This is somehow misleading and rather should be an "*". Can I

Hi.
I am trying to split raster map into chunks to do calculations (with
r.mapcalc) on each chunk separately.
I browsed the net and found only the script called r.split.line, which
needs vector file to split raster, but this is not that I want.
Is there a way to split raster by rows? For example
Markus,
I understand your arguments, but "A" is the slope of r.slope.aspect and
has floating point values as input for the formula. I just created a
testcase to be able to report on the behavior in detail. As you can see
below the results are truncated to integer as soon as I add a term to
"A

r.info (http://grass.osgeo.org/grass64/manuals/html64_user/r.info.html) to
get the raster extent
g.region (http://grass.osgeo.org/grass64/manuals/htm
The function r.tileset (
http://grass.osgeo.org/grass64/manuals/html64_user/r.tileset.html) allows
you to split your raster layer in user-defined tiles (which could be a tile
of one row). The description states that it "produces tilings of the source
projection for use in the destination region and
The gdal_translate utility has a -srcwin option where you can speciify
row/col values to "clip" a raster. If your data is Geotiff to begin with,
this would be an easy solution.

Note that
(A+1/100) = A+(1/100) = A
as 1/100 will use integer division.

Thank you Paulo! I think your way is feasible. For r.series, t could be
caluclate via R2 using r.mapcalc. I am also a newcomer to time series
analysis. Hope r.series may add t,f, p function soon.
Best regard,

Hi,
yesterday with Anna and Vaclav we added a new module `g.gui.mapswipe`
in G7 which allows to launch wxGUI Map Swipe as standalone
application. Today I did the same for Graphical Modeler. So currently
you can launch the Graphical Modeler also from CLI
g.gui.gmodeler
or
g.gui.gmodeler file=.gm
Hi,
I'm experimenting with the gui modeler (thanks for a great tool by the
way !) trying to build a very simple model of city growth, starting with
a very basic cellula automata style model where the state of each pixel
at time t+1 depends the state of its neighborhood at time t.
In Python t
I have two different vectors that I would like to patch together. one
doesn't have an attribute table associated with it. The other does. I
am having a problem figuring out how to get them to play nicely. At
this point It would be easier to just create an attribute table... All
help is gre
Great, thanks

I would like to point you out that r.
Stephen -
Adding an attribute table to the input map is probably the best thing to do!
You can create the patched vector with no attribute table, and add it
later - but you'll then have to go back and use other tools to create a
table and fetch attributes from the original.

*Dear madi,*
Ok, I know it but according to our requirement we need some customization.
We are also focus on psmap flooding scripts.

Yes - this is why I still think that the manual should be upgraded:
make documentation be full tex
