Hello all.
I have three points for which I create three areas with v.buffer. However, this new polygon map have no attribute table - so I create one with v.category and v.db.addtable. This gives an attribute table with 3 categories but they are all linked to all polygons! I won’t each polygon to have a separate category.
Anyone knows what to do?

This is fixed only in GRASS 7, here, v.buffer can preserve attributes
in the output. Furthermore, v.buffer in GRASS 6 is not working well,
there are a number of known bugs.
Alternatively, you can delete categories with
v.category option=del cat=-1
followed by
v.category option=add cat=1
Each polygon will then have its own unique category.
