De vraag blijft: moet ik mappen wat ik ZIE of mappen hoe het MOET ZIJN? Iedereen weet dat een verkeersbord C3 zonder vermelding "UITGEZONDERD FIETSERS" of "UITGEZONDERD PLAATSELIJK VERKEER" fout is op een weg die speciaal is aangelegd voor fietsers (oude spoorbaan).

It's completely impossible to mold the entire world into a set of tag rules without exceptions in any country at all. It already starts with the definition of each different category of vehicle, so we couldn't even make a tag set which is valid for the entire world if we were to tag every vehicle type explicitely (think roads that have motorcar=yes, goods=yes, bicycle=yes, motorcycle=yes, foot=yes, horse=yes etc). We in Belgium have two types of mopeds, in other countries they have mofa and moped, other countries have a single type of moped, and then the rules start to change what it means exactly if you tag a road with moped=no. So yes, we have to have country defined rules about access tags. And one of them is that access=destination will always allow pedestrians, cyclists and horse riders in Belgium. Another one for example is that a motorroad=yes will disallow pedestrians, cyclists, mopeds, horse riders and other animal drivers without having to add all these explicitely. I know it's not an elegant solution, and that it does put a big burden on all data users to interpret what access tags mean in every country, but I always had this "dream" already quite some time ago that one day some kind of a library would be built that would take the tags on a road, and then you can ask if a certain vehicle is allowed or not for that given country. A place where all these local country rules would be defined. But I guess that's beyond this discussion :-) Greetings Ben _______________________________________________ Talk-be mailing list Talk-be@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-be _______________________________________________ Talk-be mailing list Talk-be@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-be
