[GRASS-user] Re: Envoking GRASS in a python script

Thanks for your help Glynn I have now got it to work! Just a couple of things, this... os.environ['PATH'] = os.pathsep.join(os.environ['PATH'],bindir,scriptdir) ...should have [] around the arguments so as to make a list as the join function can take only one argument, so it looks like this...

[GRASS-user] odd r.stats output, after r.resample.stats

Re: [GRASS-user] v.vect.stats has no results

Hi, I am sorry, the module v.vect.stats was missing in my set-up. I tried to start it through GUI-CLI, that was the output. Now I upgraded GRASS-7 to r48840 or r48841 (I guess, sorry, I cannot check, the Internet connection of office is down), and v.vect.stats works fine. Thanks for your sup

Re: [GRASS-user] v.to.points

Thanks a lot! (actually i'm feeling kinda dumb!! :) ) I assumed the output would be external to GRASS because of the browser buttom [. . .] Problem solved! 2011/10/18 Marcello Gorini > As far as I know, v.to.points does not write to an external file, it > creates a point vector map within GRAS

Re: [GRASS-user] v.to.points

As far as I know, v.to.points does not write to an external file, it creates a point vector map within GRASS. So you should do output=pointmap and then use another module such as v.out.ascii to generate an actual text file with the points. Also, when you do that, do not enclose the output portion

Re: [GRASS-user] v.vect.stats has no results

Hi, .. v.vect.stats uses the key column recorded in the db link info. If there would be a problem with the points vector, v.vect.stats should print something like area_cat|count|average 1|0|null 2|0|null 3|0|null Maybe rebuilding topology helps? I created a new vector of points (tmp4) usi

[GRASS-user] Is it possible to derive both banks of a river ?

Dear friends, I derived this accumulation map from 90m srtm data. Across the river, the accumulation varies and the river line passes through the maximum of these values. Typical Scenario: On right bank Acc= 3 Near Right Bank Acc=10

Hi! What I am doing wrong, or is this the problem of v.vect.stats? I have an area vector "area_vector" of three rectangular areas and a vector "point_vector" with numerous points inside these areas. The output of the command v.vect.stats -p points=point_vector areas=area_vector type=point p
