Ok. So I educate them, put them through an online testing system. And then the chance that they classify something as a trunk road that is in fact a primary road is still much greater than the chance that properties of that road will change due to the government changing the rules for all primary roads throughout the country. If we want to accept anonymous or semi-anonymous edits, we need to capture the information with the highest signal to noise ratio first. (Wikipedia does this by asking people to site references). The access restrictions applicable on bicycles are usually quite clear, so the signal to noise ratio is high. Distinguishing between A and B roads and converting that into OSM classifications is much more error-prone. >> I wouldn't be able to distinguish between and A road and a B road in >> the U.K. and that's what highway=road is for.

It's the niche that OSM occupies. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
