Hi,
I feel like I'm being thick, but ...
v.buffer creates a map in which all centroids are assigned the same
category value (ie, 1). How do I assign a unique category value to all
centroids?
If you just want to assign any values: v.category.
If you create buffers around points which have category values and you
would like to assign those values to the buffers, you can then (after
v.category) do something like this:
v.db.addtable yourbuffers
v.db.addcol yourbuffers col="pointcat int"
v.distance from=yourbuffers to=yourpoints dmax=0 upload=cat column=pointcat
