Hundred-hour flood

Posted by Minh Nguyen on 4 October 2008 in English (English)

The past few months, I've been turning the Little Miami River in Southwestern Ohio into a space-filling river. Every time I touch it, though, the area “floods”, because I keep forgetting to keep the river’s ways going clockwise and each island or sandbar going counterclockwise. Between Mapnik and Osmarender, I can’t ever keep the place dry. :^) There’s gotta be a better way.

Location: Miami Bluffs, Hopkinsville, Warren County, Ohio, USA

It turns out this time the problem was that, when I joined two of the river’s ways together, it simply overlaid the existing ways with another, longer way. That threw Osmarender way off.

Coastlines are messy for complex stuff like this anyway. Better to use waterway=riverbank on a series of not-too-huge closed ways or multipolygons.
