it was the "gravel over" part that i (still) don't understand. > I would consider a gravel-paved road > (http://en.wikipedia.org/wiki/Gravel_road) to be not a highway=track in > OSM terms, in most cases. i agree. > Further, I would expect that gravel-paved roads are the most common of > non-concrete-paved (including asphalt concrete) named roads, not in my experience. > and that > most true dirt roads are unnamed. perhaps. but i'd say that's mostly only true if they're not publicly accessible. any sort of public right-of-way usually comes with at least a locally-assigned number: "Forest Route NN", or "Fire Road NN", or "County Road NNN". > And finally I would agree with you that regardless of their relative > numbers, true dirt roads (not gravel) as described at > http://en.wikipedia.org/wiki/Dirt_road should indeed be highway=track. no, i don't agree. as greg troxel (i think) said earlier, the term "track" implies a private right-of-way. there are many many dirt roads in my travels that are better described "highway=residential surface=unpaved", due both to their public nature, and the presence of multiple residences. paul =--------------------- paul fox, p...@foxharp.boston.ma.us (arlington, ma, where it's 70.3 degrees) _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
