Well - cases like http://maproulette.org/#t=waterways-direction/8300823723664637270 are pretty clear cut - no need for other data. If you'd be able to switch to a background map with relief rendering like the cyclemap even less clear cases can often be properly determined. It is also a matter of motivation i think - if you can clearly see the error you are much more motivated to fix it. Of course showing the direction of the other waterways around would be very useful - but probably difficult to implement. I would always show the currently mapped direction - so the potential answer 'this is not an error' matches that rendering. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
