Hi list,
this weekend I ssh'd in computer to let some processes run in the background so
I have my results tommorow.
However my script crashes on a strange error related to r.mapcalc. I tried some
r.mapcalc commands within the ssh'd GRASS session and I get the same error.
for example:
Hi list,
just want to share some code that could be useful to some of you.
I was looking for a way to do other patch based statistics than those provided
in r.statistics. Using masks and a loop in GRASS was terribly slow (certainly
for very patchy areas (in my case some 10). So this is
Hi list,
I'm trying to use r.out.ascii to dump a map (or better a masked part of it) to
stdout. I would then use sed to clean up the data so I'm only left with the
pixel values and no spatial information (don't need it).
However, If I run something in the lines of:
r.out.ascii -h input=patch
Hi list,
for a validation exercise I need to extract the class values around certain
pixel location.
I have a map with all the locations (numbered) and a map with the validation
map.
The code you find below is the one I came up with to get this information (only
output to terminal for the

Hi list,
I've got two maps, a map with patches or areas which I want to evaluate. A
second map contains a parameter which I want to evaluate (average, std) based
upon areas as delineated in the first map. The output of all this would
optimally be a third map with the results of the evaluation
Hi list,
I don't know who maintains the grass site but I couldn't reach the latest
builds of grass from Lorenzo Moretti for Mac OSX from the link provided by the
grass site. It seems that the page has moved to

Hi list,
I'm looking for a way to extract the occurence (number of pixels of a certain
class in a moving window) of a certain class in a moving window neighbourhood
and write this to a map. r.neighbors only provides summarized versions of what
I need. Is there a way to calculate this basic
Hi list,
I've recently noticed that when exporting maps as Geotiff GDAL adds an extra
row and column to the map. Within grass this data is not there. For example my
map that measures 4509 rows and 4359 columns gets exported as a tiff of size
4510 by 4360.
The added row and column are empty
Hi list,
I'm currently working on a project where it would be nice to have user friendly
and above all limited interface to an automated GRASS routine. Is there a quick
and easy way to call GRASS from within other code (preferably a fast scripting
language)? Furthermore, is interaction
