It's not that straightforward to me since tracktype is described in terms of surface materials, which can have widely varying levels of compaction. But great, I'll update the articles trying to make this distinction clearer, then post back here my changes. On Sat, Mar 15, 2014 at 1:59 PM, johnw

Here are a few arguable reasons to split the waterway and tag it with layer=-1: 1. Bridges may come in pairs for dual carriageways. In this case, it's a single layer tag for the waterway versus 2 layer tags for the bridges. This may happen many times in a row. In this case, it makes sense to split

I thought a bit more and this statement I said is incorrect: "Correct, let's add "within the same level" to all of those rules, and assume level=0 when level is not specified in a tag. Then they all work also for indoor mapping." The correct wording of those warning rules, taking indoor mapping i

Please correct me if I'm wrong, after reading what you said, I think that the point that I was missing was this: - "tracktype" is the "degree of compaction" of the material (regardless of material) - "smoothness" is the "degree of irregularity" of the surface (for wheeled vehicles, also regardless

Hi, I agree partially with you here. Yes, adding bridges in addition to the road is possible and may be a good idea. What we currently map as being a bridge in fact is the property of "the road is on a bridge" instead. Changing the current tagging scheme to "duplicate the corresponding segment of
