This is a totally enclosed overbridge linking 2 buildings on the Waikato Hospital Campus. It crosses over, but does not connect with, Pembroke Street below. https://www.openstreetmap.org/way/354971865 At present it is tagged 'highway=pedestrian' and 'bridge=yes' based on its appearance on Bing imagery and has given rise to this KeepRight alert http://keepright.ipax.at/report_map.php?schema=50&error=78138632 - "way not connected with the rest of the map" In my opinion the tag 'highway' isn't the most appropriate and I wonder if the feature would be better drawn as an area (linked to the buildings on either side) and tagged 'building=bridge' and 'layer=1' https://wiki.openstreetmap.org/wiki/Tag:building%3Dbridge Advice appreciated please. asked 28 Jun '15, 04:51  NZGraham |
One Answer:
As usual you have always different (detailed) approaches on tagging in OSM. So for your quesion it's IMHO
The first one is easier and maybe more useful for indoor routing, while the second one is more likely for 3D rendering. For example I took the last one here in Rostock or here in Schwerin for a similar solid bridge/tunnel. answered 28 Jun '15, 09:41  iii |
Even with indoor rendering, you want to have a building or building part around the indoor elements, so #2 is clearly the best option.
