Well, for the current detail that might be true. When all bridges and tunnels are mapped, all changing surfaces on minor roads, etc. you will have much more nodes than in this link. IMHO it is pointless to post a zoom 14 link and say that 19 points are too much for a linear feature of about 5 km in the link (where nothing else is mapped to give context). I agree that sometimes linear features have too many nodes (especially most mappers don't use them well, they tend to use regular distances regardless of curves or straight parts) but I hope that if someone creates a tool to simplify the geometry it will use angles and not just distances in its algorithm. The current "simplify way"-features are deforming well mapped ways. In reality I see mostly the opposite: ways with far too few points (in low version numbers). In respect to when all these ways will be mapped with a more appropriate node density (and all the missing roads will be present, that we are now lacking, e.g. in Asia, Australia, Africa) deleting some pointless nodes is not a solution (e.g. see here: http://www.openstreetmap.org/?lat=41.93815&lon=13.70882&zoom=17&layers=M ). Of course I do delete pointless nodes, but that's far less than I add ;-) cheers, Martin _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/listinfo/tilesathome
