What is missing in the manual that the option length can't be found?
Helmut, Nothing. What I used: # calculate stream lengths v.db.addcolumn map=wrb_rivers columns='length double precision' v.to.db map=wrb_rivers opt=length column=length units=kilometers db.select sql='sum(length) from wrb_rivers' Works like advertised.
