This is a pretty common staircase type where I live but how do I map it? Should I make lines over each other multiple times, each with different level? Or just one line and don’t care about the other floors? I don’t know if I’m searching for wrong terms but I have a surprisingly hard time on getting info about stairs mapping.
Can you point me to the right direction or post some example?
“Ideally”, yes. It is very annoying to do in most editors but it is the correct solution.
This is also fine IMHO, just mapping it as a single line with
highway=steps
will get the point across. Especially so given how this is not going to be useful for routing.For multi-level stairs that are actually useful for routing the first solution would be more preferable as it would help calculate the distance traveled slightly better. You can actually see this done semi-properly here: https://www.openstreetmap.org/way/451708239 (notice how the staircase is mapped in a spiral - this is mostly due to how annoying it is to do proper overlapping ways in an editor).
If you use simple indoor tagging, you can use
repeat_on
, and you can map this with a single line: https://wiki.openstreetmap.org/wiki/Key:repeat_onThere are some renderer support for it, I’m not sure any routing engine supports this.
