I’m trying to understand what the consensus is with mapping crossings as ways and nodes. Mapping with only a node that has
highway=crossing is a valid option, nobody denies that. We get problems when crossings are mapped as ways. Do we map with only a way with
footway=crossing, or do we also add a node with
I looked at a few European cities, and got a percentage of crossings that are tagged with only a way, without a node, versus all crossings tagged as ways:
Data shows that (at least in Europe) a majority of crossings that are mapped with a crossing way, are also mapped with a crossing node in the middle.
While trying to find which mapping style is “more correct”, the only discussion I found is this one on the Discussion page of the highway=crossing wiki. There it is said that tagging both with a way and a node is a Violation of the One Entity One Object Rule, but that this state happened because people didn’t want to delete crossing nodes when adding ways.
What do we think about this?
