Add indoor support with level switcher

[Unkn0wnCat]

Hi all,

I think if the user is zoomed in onto a building, a selector for floors should appear on the bottom right, so the user can look at the data for individual levels. This would allow for way better indoor support and allow for users to explore the inside of buildings easily.

This is one of the big things Google Maps currently has, which none of the OSM apps have (as far as I've seen)

Let me know what you think!

This is a good idea, but it requires some effort to implement in our graphics engine and in the data processing layer. Are there many mapped indoor locations in OSM already?

I'd love to see that and it would make OM stand out when being compared to other OSM based apps

Would absolute love to see this implemented and it would motivate me to actually start indoor mapping as well.

There are +300k indoor keys

Yes, we would have more contributions with a mobile app showing them. It would be great in Organic Maps! ;-)

Looks like streetcomplete will soon ask users for the level of a shop
Meaning indoor maps would soon be a lot more useful once the data has been collected

Cool! Any contributions to OM are welcomed!

Heres another indoor mapped area if you want another example
