That's roughly what I've been doing, Drive or hike there, and decide on the values for those tags while standing there. I'm still curious about "narrow" though. :-) I don't think smoothness gets rendered though, and everything is usually a grade2, so somewhat meaningless. > itself.

Yep, we teach our trainees that, and since we use current USGS topo maps as basemaps in OsmAnd, you get that and the OSM data. Best of both. Sure beats the days we used a thick paper map book, and a bag of topo maps. Personally though, what the USFS uses to determine that difference doesn't seem consistent, and over many years, the road conditions change drastically due to erosion. I prefer to go there in a high-clearance vehicle or UTV and decide after driving it. - rob - _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
