No errors!
Hmmm... ! I though that it works as follows (and did):
1. Open a raster and give a name for the new raster (open a raster with
areas, all having the same value 5)
2. edit, save, exit (I erased lots of pixels from various areas by
assigning the * -- that is NULL, no?)
3. load the NEW
O! I got it!
It's the * I am using. With the value 66 for example it worked!
But why not with *. It's a perfect tool if one needs to manually
correct some details.
And why not having a magic key with which one can fly over pixels
with the mouse pointer and assign new values instead of

FYI
I've just populated the wiki page related to Natural Hazard in the
application section.
This page could be an opportunity for users working in environmental
modelling, natural hazard, risk assessment, and others to collaborate in
creating a review of existing models, procedures, and works.
I was thinking about the circular neighborhoods that r.neighbors use.
How exactly are they shaped? I mean, in a 3x3 window, does the
circular one looks like a cross? and then it start to look more like a
circle as the size increases?
As far as I understand it,
A 3x3 window would look like this:
The gpsbabelproblem is solved. I attach the correspondence.
Neverthelesss I still hope for answers of the GRASS-related questions.

Yes, Eric, that is what it does for a _square_ neighborhood. I am a
little confuse about the actual shape of the _circular_ neighborhood.
using your examples:
will a 3x3 circular neighborhood look like this:?
---o---
o-X-o
---o---
and a 5x5?
---o-o-o---
o-o-o-o-o

I had the same problem. What worked for me, with Grass 6.3RC4
installed in Applications was to do this at the command line:
sudo cp /Applications/GRASS-6.3.app/Contents/MacOS/etc/wx/gui_modules/
grass-interface.dtd /Applications/GRASS-6.3.app/Contents/MacOS/etc/
grass-interface.dtd
--Adam
So in a 3x3 example, neighborhoodSize=3, neighborhoodDistance=1, and your
first diagram has os where the mask is true. The corners of the square
wouldn't be in the mask (as in Eric's 3x3), because those points would have
the left hand side of the inequality equal to 2, making the mask false.

Thanks for the quick answer Tom.

The attached picture is a sketch I made based on what I remember from
a conference, long time ago, about some software that did interpolate
with faultlines and how it worked.

You have to import raster data in GRASS internal database in order, to
handle them.
you can do this with r.in.gdal command

Hi!
1)...
I want to create different layers..on selection user must be able to display
layers by checkbox...once user select the checkbox..he is able to see the
different layers like roads,rails,river..when he unselect the checkbox..the
layers should be removed.,..
2..)
stichining of Maps means
maybe you do not need grass at all.
try to have a look at mapserver (for the server part) and openlayers
(for the client part)
