IMHO, it's a rendering issue. First off, it also affects the current best practice (as I understand it) of mapping wider waterways as riverbank plus linear way; if the linear way is tagged waterway=stream, you get the same artifacts. Secondly, it is often the case that waterways are considered to continue through bodies of water, which would indicate the necessity of the connecting linear ways to accurately reflect local naming of water features. I know of several places in my area where a river was dammed to form a lake, the lake is known as "Such-and-such Reservoir", but the original river is still considered to be running through the middle of the reservoir and shows a such on maps. Thirdly, having a complete waterway network is a potentially useful thing (for many of the reasons the NHD adds the connecting ways in the first place) so their presence shouldn't be discouraged. My conclusion is just that the renderers need to handle linear streams on top of water areas (natural=water or waterway=riverbank) better and no tagging changes should be needed. Submitting a patch for this is on my list of things I plan to look at eventually if no one beats me to it, but that's a long list with other things ahead of stream rendering. -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- I am his Highness' dog at Kew; Pray tell me, sir, whose dog are you? -- Alexander Pope, "Epigram Engraved on the Collar of a Dog Which I Gave to His Royal Highness" ---- --- -- _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
