bike and pedestrian routing for Switzerland
by Sarah Hoffmann 09 Nov '12

09 Nov '12

Hi, I've been playing around with the new OSRM routing software lately and as a result have set up an experimental routing website for Switzerland: http://osm.lonvia.de/swissroute/ It is pretty much a clone of the original map.project-osrm.org with the difference that it offers three different routing profiles: car, bike, foot. The data is updated daily (normally finished around noon) and restricted to Switzerland only. The idea of this site is to play around with these profiles to get a more useful router for non-motorized travel. It already takes into account some extra tags like tracktype, sac_scale and surface to find you a more pleasant route tha the usual 'walk along the big, noisy motorway' but I'm sure there are others I've forgotten. The tags currently in use are summerized here: https://github.com/lonvia/cbf-routing-profiles/wiki/Profiles Try it out and let me know if you have suggestions to improve the profiles. A final word of warning: the times given are very, very approximate due to the way the software works, especially for the foot and bike profiles. Please don't rely on them if you have to catch a train or get to an important meeting (or any meeting at all, for that matter). Sarah (who apologizes for the English-only mail this time)

Hi Sarah, I played around with your site and was surprised how well it already worked, certainly better than I would have expected. The car routing worked very well. I guess on tracks with grade1 you are looking for explicit access: vehicle, motor_vehicle, motorcar, which is a good thing because many tracks are in reality only accessible for forestry or agriculture, they are just not marked accordingly yet. The bike routing worked well within your specs too, I liked the fact that it can deal with start or end points on paths, which would be unsuitable (sac_scale) and avoided otherwise. However I found that if you chose your start or end point on such a path, the routing doesn't seem to take the shortest path to more acceptable highways, but seems to continue longer than necessary on unacceptable paths, if that makes for a shorter route. In general, I agree with you that the "Bike" and the "Foot" Profiles could use more differentiation. On a racing bike with thin tires, even a bumpy grade1 track can be rather irritating, on a city or a trecking bike, tracks up to grade2 two shouldn't be a problem, same for paths with asphalt and gravel if they are not explicitly prohibited. And for mountain bikes, well, track grade3 or surface=ground is where the fun just starts. So for racing bikes, you probably want to avoid surface!=asphalt, sac_scale=*, mtb:scale=* or trail_visibility=* in general. For city and trecking bikes surface gravel/paved/concrete/cobblestone should be fine, but everything with an sac_scale>hiking, an mtb:scale>0 or trail_visibility<excellent should be off limits. And most mountain bikers wouldn't have a problem with any grade of track, mtb:scale<=1 and trail_visibility>=good, many of them would accept or even search for more challenging conditions. On foot, I would distinguish between hiking and walking around in a city. For the latter, I'd prefer surface asphalt/gravel/paved/concrete/cobblestone and avoid grass or ground (and probably sac_scale=hiking too). Thanks a lot for your website and best regards, Thorsten (Shernott)

noname Layer
by Simon Poole 26 Oct '12

26 Oct '12

I've set up yet another noname layer on http://qa.poole.ch/ mainly motivated by the suspicion that post-redaction we would have a lot of unnamed roads. This has turned out to be at least partially true. for example http://qa.poole.ch/?zoom=15&lat=47.52631&lon=7.89954&layers=TB0 and http://www.openstreetmap.org/user/SimonPoole/diary/17962 have obviously never seen a mapper on the ground.

Name-Tag des Schweiz-Zentrum-Nodes / name-tag of the Switzerland-Centre-Node
by Fred Jelk 16 Oct '12

16 Oct '12

Angeregt durch eine Diskussion[1] im deutschen Forum, stelle ich die Frage mal hier: Wie sollte der "Schweiz-Zentrum-Node"[2] benannt werden? Aktuell hat dieser Node keinen name-Tag und gemäss wiki ist das nicht korrekt. Sollte man diesen Name-Tag mit nur einer Sprache (Node ist im deutschen Teil der Schweiz) oder mit mehreren Sprachen (da mehrere Amtssprachen) versehen? Meine persönliche Meinung hierzu: in einem Name-Tag gehören nicht mehrere Sprachen, sondern mehrere Sprachen werden mit [name:SPRACHE=*] definiert. Der "Schweiz-Zentrum-Node" sollte nur einen Namen in einer Sprache enthalten - ob Deutsch, Französisch, Italienisch, Rätoromanisch oder vielleicht sogar Englisch wäre mir aber egal, das Beste wäre aber wohl in Deutsch, da der Node im deutschen Teil der Schweiz ist. Wie sehen eure Meinungen aus? Inspired by a discussion[1] in the German forum, I ask the question here in the ML: How should the "Switzerland-Center-Node"[2] be named? Currently, this node haven't a name-tag - and according the wiki this is wrong. Should this name-tag have only one language (node is in the German part of Switzerland) or should it be tagged with multiple languages (there are several official languages)? My opinion is: a name-tag should not include several languages. Several languages are tagged by [name:LANGUAGE=*]. The "Switzerland-Center-Node" should contain just a name in one language - if German, French, Italian, Rätoromanisch or maybe English doesn't matter to me, but probably the best would be in German, because the node is in the German part of Switzerland. What are your opinions? [1] http://forum.openstreetmap.org/viewtopic.php?id=18675&p=1 [2] http://www.openstreetmap.org/browse/node/1504546320
