Hi there,

In the wiki, the level tag is defined to be a 0-based-index so that
level=0 is the ground floor, i.e. at the street level. In other words, a
two-storey mall with no basement will have shops at level=0 and level=1.

This is intuitive for (at least) Europeans, people from Commonwealth
countries and parts of Asia as this coincides with common language.
However, in at least the USA, Canada, Japan, Korea, China and most
probably more regions, the floor at street level is denominated as the
"1st floor" in common language. In other words, it is a 1-based-index.

The numbering system can also vary by region within a country. Northern and central Vietnam uses a zero-based system while southern Vietnam uses a one-based system, and somehow both are national standards. [1] I'm unsure if there's a well-defined boundary between the two systems, but if there is, I like to think someone has built a building straddling the two, just to mess with us.
