I got 2 questions regarding a railway track. Whats the level of a railwayplatform thats alongside 2 bridges marked level 1, both are lying over a road and water. I would like to ad some but its not possible, shouldnt that be ? And the stairway to reach the platform, no extra level needed ? Look at https://www.openstreetmap.org/browse/way/166152585 Greetz Hendrik asked 09 Sep '12, 12:43  Hendrikklaas |
One Answer:
It is complete correctly tagged. The platforms and the part of the tracks that are above other features (the street and the river) have a layer 1, because they are relatively over these features. The stairway and the rest of the tracks don't need a layer tag because they are not relatively over something else. answered 10 Sep '12, 08:38  Roland Olbricht |
Hi Olbricht, thanks, Sorry I didnt look at the advanced options. The tracks and the platform are lying side by side on the embankment next to the bridges. Shouldnt the platform beiing cut like a road and a bridge then ? So it gets tag none beside the track tagged none ? Even a little farther theres a track 1 with a platform tagged 2 ? Im new so the system keeps surprising me.
No, not necessary. These are two different stories: Do you perceive the platform over the street and water as a different object than the rest of the platform, i.e. is it visibly a bridge? Then make it a distinct object. If the platform is rather an uniform object, then it can happily stay a single object.
The other is about the layer tags: they help to stack the objects (e.g. on a map) in a proper relative order. As there is nothing above the platform or a part of it, it may have an arbitrarily high label number. So "1" or "2" doesn't matter as long as all objects below have "0" or less.
