Dear all,
I was using GRASS version 6.3.0 and everything worked fine. Now I
installed 6.4.1 on a brand new server and I am experiencing some problems.
I want to run the scripts and the locations I had on the old grass and
when I execute the command on the new version
r.in.xyz
Hi,
I am trying to do something really simple but not finding the right way to
do it.
I need to convert nulls into zeros. I have done this:
*r.mapcalc raster2 = if(raster1 = null(), 0, raster1) *
*r.mapcalc raster2 = if(raster1 == null(), 0, raster1) **
*
But this convert all cells into nulls.
Is there a way, how to import multiple 3D GDN files into a GRASS mapset? My
DGN files include only Polylines of terrain contours from which I need to
build a DEM. I use GRASS 6.4.2 for MS-Windows (WinXP, latest stable
version).
Thank You for any idea.

Hi,
I think you should do
raster2=if(isnull(raster1),0,raster1)

or simply:
r.null raster1 null=0
(converts the original, not a second copy)
Thank you all! Solved.

Hi,
I'm getting the following error on attempting to import MapInfo files. I've
tried the two files below from different sources. Both files open and
display correctly in QGIS.

Hi all,
I've been trying to use r.gwflow recently, for groundwater modeling in
urban environments.
The r.gwflow help says that the default boundary conditions at the edges of
the region are Neumann conditions, which i understand are fixed flux
conditions. However the help does not include the
Hi,
as default the boundaries are no flow boundary conditions called
homogeneous Neumann. Hence the default flux is 0.
Best regards

That explains some of the results i'm getting, with water piling up above
the surface in the edges in low-lying areas.
Can you please tell me how i can change that to constant flux or constant

Alberto,
Your field separator is set to empty string (fs=), wouldn't that be
the problem?
