Specifies the floor where an address feature is located, using locally used method of indicating specific floor. It matters especially where levels are not referred to by numbers but by codes (addr:floor=A) or by names.

addr:floor=* should be certainly used if floor index is part of the address.

level:ref=* (if also used) will usually have the same value as addr:floor. If one want to specify that objects are at specific level but it is not part of their address then level:ref=* should be used.

There is also level=* which assumes that ground floor is level=0, the first floor above ground is level=1 and the first underground floor is level=-1. The level tag is generally used for all kind of objects and its application is not limited to address tagging. In the past, it has been claimed by some mappers that usage in some areas in practice may be different, and that this tag may be less reliable than others. If you see instances where the application of the tag diverges from its definition, please fix them.
