Re: [OSM-talk] Bridge on Hiking Trails
I always use layer= , even when there is only a single bridge. It avoids problems with the validator and - crucially - makes it clear that the two crossing ways do not have access to each other. (It also improves rendering but I probably shouldn't mention that or I'll get flamed!). Example - common in my area: If a hiking trail crosses over a canal (and its towpath) by a bridge then bridge=yes and layer=1 makes it clear that the canal and the trail are at two different vertical levels and that you cannot get from the trail to the towpath of the canal. If there is a ramp or steps from the hiking trail to give access to the towpath this can then be added as a separate way in the appropriate place. There is a theoretical dilemma as to what layer to give the ramp but I usually default to level=0 unless there is a special complexity at a particular junction that needs more explicit layering.

[OSM-talk] Bridge on Hiking Trails
Was mapping a few hiking trails with foot-only bridges on the trail and could not figure out a way to mark these bridge since the only bridge waypoint needs the same parameters as a highway. Any pointers on how to do this best? Regards, Shalabh ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Bridge on Hiking Trails
Dont think my question was specific enough. I am using JOSM for this and using highway tag means giving speed limits. I am using the path=hiking trail for the trail and would ideally need a bridge attribute 'yes' within the hiking trail.

Re: [OSM-talk] Bridge on Hiking Trails
JOSM does not give me that option of a bridge under hiking trail, atleast not while using the presets. If I use the highway tag with a bridge, consider this. I have a hiking trail marked as an 'demanding alpine hiking' 50 km from any humanity and then I have a bridge tagged as highway in the middle of it. Am I missing something here?

You don't have to use the presets to tag a feature. You can just type the tags in by hand. Which version of JOSM are you using? In JOSM build 2255, the latest tested version, the footway preset does have a bridge attribute. You may need to get a newer version. -- Jonathan (Jonobennett) ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Split your trail from both ends of the bridge, select that part and add tag bridge=yes with the + button of JOSM. Or do the same with Potlatch. -Jukka Rahkonen- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

If you use the JOSM preset Highways- Streets - Bridge, it doesn't change the highway tag. So first choose Highways - Ways - Demanding mountain hiking. That will add the tags for highway=path and sac_scale=demanding_mountain_hiking. Then choose the bridge preset - it will still have the tags for path and hiking, plus it will also have the tag for bridge=yes. Though its probably easier/quicker just to manually add the bridge=yes tag, without bothering with the presets.

Re: [OSM-talk] Bridge on Hiking Trails
You don't have to fill in *anything* in a preset. If you don't, then all of the optional stuff is left out and you only get the bridge=yes tag, which is useful if you've forgotten. Otherwise, you can just add it as an attribute. The typing completion makes it very easy. Click on Add, type b and bridge will probably come up. Then hit tab, type y and yes will probably come up. If not, then your currently downloaded data doesn't have any bridges yet. Type it out completely and the next one will complete.

Re: [OSM-talk] Bridge on Hiking Trails
I think I may understand your confusion here. You may think of highway to mean a high-speed paved road on which motor vehicles travel. But within the context of OSM, the highway tag is much more general purpose. Virtually all formal and informal roads and paths should be tagged highway, everything from limited access motorways, to paved bike paths, to alpine hiking trails. The value given to the highway tag determines what kind of path it is. Take a look at the wiki for more information: http://wiki.openstreetmap.org/wiki/Highway -Scott On Wed, Nov 25, 2009 at 6:45 AM, Shalabh shalab...@gmail.com wrote: JOSM does not give me that option of a bridge under hiking trail, atleast not while using the presets.

I assume layer is 0 if I don't add the layer tag. Hopefully this is the correct thing to assume because otherwise things will break if I have a bridge with no layer tag and a another bridge with layer=1 crossing (I'd assume the latter is higher than the former, not at the same level) Cheers ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Bridge on Hiking Trails
2009/11/26 andrzej zaborowski balr...@gmail.com: I assume layer is 0 if I don't add the layer tag. Yes, which is usually anything at ground level. Hopefully this is the correct thing to assume because otherwise things will break if I have a bridge with no layer tag and a another bridge No they won't break, it's just used to order the various ways etc when they are rendered, if there is nothing currently mapped under the bridge the layer tag is basically not used as there will only be one result returned by the query to the database. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
