Dear GRASS users: Can you give any suggestions to solve this problem?
I have an ordered dataset of segments of river currents output from r.stream.order command. I will like to add a column to this dataset that identifies each current according to Horton ordering. I mean it actually identifies the Horton number. But what I want to do is to separate each Horton current from each order. For example, if I have, say 4 Horton currents of order 5, then I will like to have an additional column that identifies each Horton current (5-1, 5-2, ..., 5-4). I try with v.build.polyline and indeed it separates the individual currents of the same Horton order. But I don't know how to incorporate that new cat ID to the current segments' dataset. Thank you for your help. -- Kenneth Roy Cabrera Torres Cel 315 504 9339
