[GRASS-user] simple shell problem

Hi why: g.region -g | awk -F= '/^nsres=/ {print $2 * 1.45}' works, but: bufdist=`g.region -g | awk -F= '/^nsres=/ {print $2 * 1.45}'` or bufdist=`eval g.region -g | awk -F= '/^nsres=/ {print $2 * 1.45}'` not work, while, wery similar structure: n=`g.region -g | awk -F= '/^n=/ {print

[GRASS-user] Signature made by i.class not accessible?

Hello all, I'm a very new GRASS user, and I hope this matter hasn't been discussed many times before. (And I hope this message doesn't arrive to you many times: I've tried sending it two times so far, and with no success. Now I'm trying from my work address, let's see if this helps.) I'm using

Hi! (Re: I can't access the signature file I've created with i.class.) 1. You enter always the same LOCATION in which you created the signatures? Yes, I only work with one location at the moment. 2. Read/Write/Execute permissions for your GIS-DB ok? I think so (although I'm not super good

Re: [GRASS-user] v.generalize for polygons?

Hamish, I played around with the map you gave me, and I think I found a way around the problem (though I'm still not very sure about what the real problem is, perhaps too many small areas or too many shorter segments (the boundary seems to be built of a number of smaller lines). I'll try to

[GRASS-user] Checking if a point (X, Y) is inside the polygons of a shape file using command line

Dear friends, I have a shape file, with some polygons. (I have imported it as vector layer.) I have a point, expressed as X,Y coordinates (Easting,Northing). I want to know if the point is inside any of the polygons in the shape file. Is there a command I can use? I would rather use

Corrado, You can do this with v.select: v.select ainput=input_points binput=input_polygon out=output_points Cheers, John On Mar 3, 2008, at 8:02 AM, Corrado wrote: Dear friends, I have a shape file, with some polygons. (I have imported it as vector layer.) I have a point, expressed as

Corrado: This is a good task for the R programming environment, which has strong geospatial tools and integrates with GRASS: Check out the following example, which solves the point-in-polygon problem for shape files:

Re: [GRASS-user] v.patch drops boundary vector regions

I had some similar problems and they were related to topology. I found this in the v.patch man page: NOTES Any vectors that are duplicated among the maps being patched together (e.g., border lines) will have to be edited or removed after v.patch is run. Such editing can be done automatically

Hello all first I'd like to make a few suggestions to enhance (IMO) our favorite GIS: - normalize the options in all modules. I noticed that while most commands take --overwrite, some (r.neighbors) use -o - some modules require a dummy value when output a list (r.mask, r.proj, v.proj..). Is this
