Re: [Tagging] noexit=yes (again) (and again)
Sorry, I may have missed part of this endless discussion. But how do I tag a dead-end sign on a road (e.g. http://commons.wikimedia.org/wiki/File:Zeichen_357.svg). These signs exist in various forms in various countries, and they are placed at the beginning of the road or stretch of roads which don't lead anywhere.

Re: [Tagging] noexit=yes (again) (and again)
This is not so obvious, because it has to be directional (for the router). If you start your route in such a dead-end street you never get out, if it's not directional. The noexit=yes on the way to me seems much simpler and intuitive. (I used the tag initially in this way, when I started with OSM. I had no doubt about it's use in this way, until I came across some discussion in a mailing list) On 31 May 2014 12:04, Martin Koppenhoefer wrote: > > > Am 31/mag/2014 um 10:06 schrieb Volker Schmidt : > > But how do I tag a dead-end sign on a road > (e.g. http://commons.wikimedia.org/wiki/File:Zeichen_357.svg). > > > > you'd tag it best on a node with traffic_sign=* (e.g. dead_end) > > cheers, > Martin > > ___ > Tagging mailing list > Tagging@openstreetmap.org > https://lists.openstreetmap.org/listinfo/tagging > > ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] noexit=yes (again) (and again)
What does the router have to do with the traffic sign? What information does it get from it that can not be easier got from the topology?

(I used the tag initially in this way, when I started with OSM. I had no doubt about it's use in this way, until I came across some discussion in a mailing list) Tagging it on a way can just be as confusing. The router might never enter the street, because right at the begging of the street it says noexit=yes. Bascially you don't have to tagg it for the router at all, because it will see there is a street that does not continiue. And if it continiues with a footpath then it will see that you can't drive there with a car. Because of that alone a nonexit=yes is a bad solution as default tag for dead end road when there is a sign, because often people on foot or bike can still continue, but nonexit=yes suggests they can not. __ openstreetmap.org/user/AndiG88 wiki.openstreetmap.org/wiki/User:AndiG88 ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] noexit=yes (again) (and again)
Any decent router will totally ignore a noexit=yes tag as it determines the topology from the actual ways and how they are connected. The noexit=yes tag serves only one purpose and has two different "data consumers": the next human mapper that comes along and automated QA tools. It allows those two data consumers to know that a way that ends close to another way but is not connected to it is not a mistake. For that purpose it should be on the node at the end of a way that is very close to but not touching another way. I agree with Martin that if you wish to tag a street sign that says "no outlet" or "dead end", then put a node where the sign is and tag it with "traffic_sign=*". -Tod On May 31, 2014, at 3:46 AM, Volker Schmidt wrote: > This is not so obvious, because it has to be directional (for the router). > If you start your route in such a dead-end street you never get out, if it's > not directional. > The noexit=yes on the way to me seems much simpler and intuitive. > (I used the tag initially in this way, when I started with OSM.

The matter is simple and is spelled out in the snippet from Tod. I use the noexit tag on the last node of a highway that offers no way forward, mostly for other mappers so they do not have to investigate these dead_ends again. Tagging the way makes no sense to me because there could be legitimate routable destinations before the dead_end is reached. If you must tag something at the beginning of a dead_end, tag the sign.
