Quick start

In the XYZ tiling system, the region of the world from 85.0511 (more precisely: arctan(sinh(π))) degrees south of the Equator to 85.0511 degrees north is covered at zoom level 0 by a single tile. The number of tiles at each zoom level is 2**(2*Z). At zoom level 1, we have 4 tiles.

You can get the tile containing a longitude and latitude pair from the mercantile.tile function.

>>> import mercantile
>>> mercantile.tile(-105.0, 40.0, 1)
Tile(x=0, y=0, z=1)

You can get the geographic (longitude and latitude) bounds of a tile from the mercantile.bounds function.

>>> mercantile.bounds(mercantile.Tile(x=0, y=0, z=1))
