Dear Grass-experts
I have a categorical raster map with 5 classes.
Now I need to estimate some stats using different-sized windows
like 3x3, 5x5..25x25. The stats the I would like
to compute is to count the number of classes on
the windows, to estimate the percentage of an
class of interest (like

Hi,
I need to patch dems with different resolutions (1x1m) and (2x2 m) and
resample them to a coarser resolution (10x10 m). Which is the correct
procedure?
a. resampling the 1x1 dem to 2x2 using r.resampl.stats -w (to be more
accurate)
patch them all at 2x2, resample the patched dem to 1

Running Amarok (music player) for the first time asks which database to
use (to store music info). The "wizard" dialog states: MySQL and
Postgresql are faster than sqlite, but require additional setup.
I though that sqlite is faster (but with some multi-user access
limitations). So, what is faster

Hi,
Take a look at the r.what man page...

I did something similar but for a few points. What you will have to do
is create a list with the x,y coordinates that you want and then pass
it to r.what
You could create your x,y list by hand or, using
