I've gone ahead and cleaned up the NHD page a bit. I've also looked at the data, and I must say I'm confused! One river is represented in the flh file as waterway=stream, in arhi as waterway=riverbank, in flmd as waterway=stream (but with worse spatial accuracy than flh), and then in armd as waterway=riverbank! I suppose one of the waterway=stream's should be changed to waterway=river, and only one of the waterway=riverbank objects should be used.
Is this really what the NHD data is like? It will take more time than I thought to properly merge these these 6 or 7 layers. If I am confused, then please enlighten me. Preferably by putting it in the wiki :) http://wiki.openstreetmap.org/wiki/NHD -Josh On Thu, Jun 9, 2011 at 2:37 PM, Josh Doe <[email protected]> wrote: > Can we improve the documentation on the NHD wiki page in terms of the > import process?
