Hi all, Slightly off topic, but I was recently wondering if there was a waterway routing tool available? As in, I'd like to click a point in a waterway and have the downstream route plotted, presumably to the sea. It appears to me that a tool like that could be useful in this discussion?
Despite my best efforts, I keep finding river drainage basins fascinating :) Cheers, Joseph On 23 February 2018 at 10:35, Rory McCann <r...@technomancy.org> wrote: > On 23/02/18 06:53, Maarten Deen wrote: > >> I see nothing wrong with those examples, I would do it the same, >> especially if the rivers can be sailed on by boat.
