Greetings
I'm doing some work in GRASS with a couple of friends from different
countries (/ different languages) and our GRASS has some words translated in
in our own languages but this can be quite difficult when, for example, I'm
running something on a laptop of an italian :). So I want to
Hello,
I have a line-vector (river) and some points on that line. First I am
straightening that line with v.generalize (method: boyle). Now, there is the
problem that the points are not exactly on the line anymore. So I want to snap
(move) the points to the new generalized line again. Which
Hi Gaspar,
r.mapcalc new.map = if(flat_map==0.0234,flat_map,null()) - if you
want to preserve original values
or
r.mapcalc new.map = if(flat_map==0.0234,1,null()) - if you prefer to
assign a value of 1 to those values equal to 0.0234 in the original
raster map
It should work.

ignoredDelimiter = ''
Thanks a lot, I will try to patch it.
probably you will find more such statements in the code (see eg.
r45962). In that case, could you send a patch which I could apply in
SVN?

Hello.
I am trying to add some raster maps. I thought I could do this in r.mapcalc,
but new_map= old_1 + old_2 seems to produce a map where the maps overlap and
ignoring areas where only on of the maps have values. I would like to do
something similar to v.overlay operator=or.

I would like the NULL values that overlap with none NULL values to be treated
as 0, and still have NULL values where both maps have NULL values. The combined
map would be a large map with NULL values and added values.
Maybe the best way is to use r.null and set NULL values to 0. Add the maps
Hi all,
how to assign height value(z) to a particular pixel having x and y
coordinates in an orthphoto using grass.
Thanks in advance,

hy,
i guess r.patch can do that for you

I have a Land Cover map and I want to substitute Land Cover codes by
numbers. Besides r.reclass (1 = 1 Agriculture ; 2 = 2 Forest 3 = 3 Water)
what other method does exists in GRASS?
Thanks

Don't know who of you led me in the right direction, but eventually the line:
C=A + if(isnull(B),0,B) in the manual solved my issue.
New_map = if(isnull(old_1),0,old_1) + if(isnull(old_2,0,old_2)) + etc and a
following new_map=if(new_map0,new_map,null())
I had four maps in my case, and that is
Hi! Gaspar,
you can do it one way as follows.
1) create a vector of desired area that you would like to extract values
for.
2) use v.to rast for converting it into a raster use value = 1 for that
raster
3)open mapcalc and put input raster as A and new created raster as B
4) enter formula if(B
Thanks Markus
Just to confirm: I have to place that in etc/Init.bat right? It doesn't
matter where?
Thanks

Well it may matter...
Maybe put it in the beginning above the line:
