I tend to mark these as I think they should, if it looks like residential then I mark it that way, I don't see much point in marking it as a road unless you are unsure of what type of road it is and need someone to check on the ground. I always try to tag the source properly too, if I tag it as source=nearmap then it's obvious that I didn't survey it. > My question arises from CloudMade highlighting "highway=road" ways in their > OSM downloads, as though that was the definitive way of indicating an > incompletely surveyed road. Same could be said for anything other than roads tagged as source=survey, once you have roads mapped out from imagery you can use the validator plugin in JOSM to display unnamed roads, you can do the same with the maplint feature on the main OSM map page. Any tools such as the one you point out cloudmade have produced isn't gospel, just look at all the people that disagree with the "errors" keep right claims to exist, when it's just a difference of how something should be mapped and not an error at all. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
