[GRASS-user] Assign attributes of start and enpoints to connecting lines

[Hanlie Pretorius]

Hi Richard,

Your suggestion worked in principle, but the whole operation needs
more work. I ended up with the same node names in the start and end
node columns, so I think a script is needed to identify the start and
end nodes based on the direction of the flow of the river. An
elevation column in the points layer could provide this information.

Regards
Hanlie
