[GRASS-user] How to categorize my areas

[Alec Ventura]

Well i found out that the problem is that my attribute table is not been copied when i run the v.buffer command, so i dont have a 'cat' column as i do on PocosUTM22s vector. I run the v.buffer with the -t flag and everything is ok now

Subject: [GRASS-user] How to categorize my areas




I have a vector with some points (about 80) and im generating a buffer around then:g.run_command('v.buffer', input='PocosUTM22s', output='boreholesGrassBuffer', type='point', distance='1000')
then i want to extract then one by one so i can make a 3d area with extrude command, the problem is that when i run the extract:
v.extract -d list=1 input=boreholesGrassBuffer output=test1 type=area
my test1 vector has all the points, if a undestand correct the list parameter of v.extract is related with the category, but how can i categorize each area of boreholesGrassBuffer vector?
Tnks,Alec.
