[GRASS-user] Re: combining and evaluating vector dbf values

Nearly there but not quite: The final column should combine the values from the 2 columns, am I right that concat doesn't work with dbf? So this doesn't work echo UPDATE vectormap SET c_COVER = a_COVER || a_value | db.execute cheers, maning On Tue, Nov 25, 2008 at 2:34 PM, maning sambale [EMAIL

Hi, Any help in doing the following: I have a combined vector in grass using v.overlay I now have a dbf table with the following a_value = integer a_value2 = integer b_value = string Now I want to combine the categories in another column (c_value) like : evaluate b_value, a_value, a_value2

[GRASS-user] How much training areas is enough?

Hi, In doing remote sensing classification, we are advised that more training areas is best, but how much really? There must be a threshold where it is pointless to add more since it will not contribute significantly to the classifcation process. I would like to ask what are the standards/best

Testing GRASS Addons (Re: [GRASS-user] Re: [AniMov] GRASS Addons for the estimation of home ranges)

I would like to test some of the GRASS addons for evaluation/inclusion to main Grass code in (Mac and Ubuntu). I will probably use the stable release as a test environment and of course North Carolina dataset. Any specific test results I should submit? This is the info I got from the wiki:
