DIDOK compare map
by Michael Spreng 11 Nov '12

11 Nov '12

Hi, I have set up a DIDOK compare map on http://didok.osmd.ch/. For those who don't remember, in 2009 we imported the public transport stops from the BAV (http://wiki.openstreetmap.org/wiki/EN:Switzerland/DIDOK) The compare map should give you an idea about: - potentially missing stops in OSM: there is a new DIDOK list every year. I use now the one from 2012. If you can't find a DIDOK stop on the ground, you can mark it as invalid on the map. - still existing OSM data for potentially deleted stops. - large deviations of OSM and DIDOK. But almost always OSM is right (except the nodes which are still from the initial import of 2009, and were corrected in the mean time in DIDOK, but not in OSM) If you use the coordinates from the DIDOK compare map, please mark it in OSM as source = Bundesamt für Verkehr (BAV), DIDOK 2012 The map is updated hourly. I hope this is useful, but use it with care. The DIDOK data is known to be terrible in certain areas. Use it to plan your next survey, or find out the correct uic_ref number or uic_name. But don't copy blindly from DIDOK. Michael

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)

Stammtisch Zürich im November 2012
by Sarah Hoffmann 01 Nov '12

01 Nov '12

Hallo zusammen, der nächste Termin für den Zürcher OSM-Stammtisch wäre der 11.11.12, was mal wieder ein Sonntag ist. Wir könnten uns am Sonntag wieder einmal in Cham treffen. Allerdings würden uns für diesen Stammtisch gerne zwei Studenten der HSR besuchen und ihre Arbeit mit OSM vorstellen. Sie können aber nur unter der Woche kommen. Wir müssten den Stammtisch dann also entsprechend verschieben. Was ist euch am liebsten? Stefan hat einen Doodle aufgesetzt, wo ihr eure Terminwünsche entragen könnt: http://doodle.com/gftca59mz4ece8at Alles natürlich wie immer unverbindlich. Gruss Sarah

Re: [talk-ch] bike and pedestrian routing for Switzerland

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.
