Hi, Can somebody please share with me what the hierarchy of the data is (for layers)? I've tried to take a look at the data myself, but would be great to see if there are a set of rules in place. For example - it looks like bridges which are of a height >50m are always assumed to be layer 5. What are the rules for this? asked 26 Sep '16, 05:26  Kyuusho edited 26 Sep '16, 05:28 |

There are no rules about the drawing order if that's what you mean; every map style has to decide for themselves what they want to do. The layer tag is used to model a local layering but the 50-meter-bridge rule you mention is not a general rule, just something someone has made up for their particular map style. answered 26 Sep '16, 07:41  Frederik Ramm ♦ |
Hi, The layer tag is fully explained here :- https://wiki.openstreetmap.org/wiki/Key:layer , with a few examples. answered 27 Sep '16, 07:07  BCNorwich |
Can you describe your problem in a bit more detail? It may be that we don't understand what you're trying to ask.
