[z, x, y] of slippy map tilenames as a space partitioning code, in the form of {z}-{x}-{y}.


I wanted to give a catchy name for the slippy map tilenames tile number.

Specification for what3numbers

A what3numbers is the tile number in slippy map tilenames concatenated by hyphens(‘-‘) in the [z, x, y] order, e.g., 2-3-1.
