Dear community,
Can someone explain me the difference between r.convergence and the TCI calculated by r.terraflow.
Best regards

Hi fellow GRASS users,
I have outputs of i.segment (object segmentation) for 30m Landsat imagery
from 4 dates. The segments are around 10000 each for each imagery. How can
I use these outputs for land cover change analysis? Do I have to vectorize
these and recode the classes, or is there a more efficient way?
Thanks!
Jaya

Hi all,
today, I have a problem with my release "grass 6.4.4 with my sis " in
windows vista.
When I open my mapset, appears this error:
“g.proj.exe ha smesso di funzionare”.
Someone has an idea for a solution.
thanks in advance.
Giuliano

Following Anna’s suggestion I had to find out that r.mode has to option
to handle NULL values, i.e. exclude it from calculation? I need to
aggregate rasters to polygons, with rasters covering only a small part
of the polygon. As I realized now r.mode returns NULL in such case.
Setting NULL with r.null null=9999 it will return 9999 for all of these.
Is there a solution to that problem?

Is it possible to get the “mode” (most common occurring value) in
a polygon for discrete classes? It appears that v.rast.stats does
not have this option.v.rast.stats uses r.univar and r.univar doesn’t have mode implemented
(it’s a TODO in manual). You can look at r.mode but it returns raster
map, not one number.Anna
Thanks for a short feedback,
Patrick
