Re: [HOT] Waterway mapping advice needed...
Thanks for the responses guys. I'll take a look and decide a course of action, which may include reworking the task slightly. This is one of the first I did and I don't think I realised the workload involved in such a large area.

Re: [HOT] Waterway mapping advice needed...
Hi Pete From JOSM WMS/TMS preferences, the OpenCyclemap layer is available. It provides elevation contour lines. If you select this layer, it should help to see in which direction the waterways flow. But not always easy to interpret. Looking at the secondary highway at the bottom of this task highway=330089042, it seems that this is at the top of a hill and that all waterways flow in opposite direction from this highway.
