Me too. > but agree it definitely needs the multiple (documented) > definitions of completeness. Apart from some linear scale (e.g. 1-5 as suggested), I think we might also need some more specific approach for the areas covered by the AND and TIGER imports. Both will perhaps score 5 on the completeness scale for roads, but for example AND imported data needs some work to get it "up to standard" [1]. Also, most tracks and cycleways are not present. It would be nice to be able to say that for some area that (e.g.) - road data is from AND and partially verified; - major tracks and unsurfaced roads are added; - cycleways are complete; - amenities are not added. On the other hand, to be able to more easily render a nice map (overlay?) of completeness, it might be better to re-define the linear scale for these areas... (Which, I know, is perhaps not very nice.) [1] http://wiki.openstreetmap.org/index.php/AND-NL:_Todo Dutch todo list regarding data imported from AND. For example all ways not accessible by cars are tagged as highway=pedestrian. On a case-by-case basis this needs to be changed to e.g. footway, cycleway or left pedestrian. -- Freek _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
