Spherical mercator coordinate and tile utilities

Documentation: http://mercantile.readthedocs.io/en/latest/

The mercantile module provides ul(xtile, ytile, zoom) and bounds(xtile, ytile, zoom) functions that respectively return the upper left corner and
bounding longitudes and latitudes for XYZ tiles, a xy(lng, lat) function
that returns spherical mercator x and y coordinates, a tile(lng, lat, zoom) function that returns the tile containing a given point, and
quadkey conversion functions quadkey(xtile, ytile, zoom) and
quadkey_to_tile(quadkey) for translating between quadkey and tile
coordinates.

.. code-block:: pycon

>>> import mercantile
>>> mercantile.ul(486, 332, 10)
LngLat(lng=-9.140625, lat=53.33087298301705)
>>> mercantile.bounds(486, 332, 10)
LngLatBbox(west=-9.140625, south=53.12040528310657, east=-8.7890625, north=53.33087298301705)
>>> mercantile.xy(*mercantile.ul(486, 332, 10))
(-1017529.7205322663, 7044436.526761846)
>> mercantile.xy_bounds(486, 332, 10)
Bbox(left=-1017529.7205322663, bottom=7005300.768279833, right=-978393.962050256, top=7044436.526761846)
>>> mercantile.tile(*mercantile.ul(486, 332, 10) + (10,))
Tile(x=486, y=332, z=10)
>>> mercantile.quadkey(486, 332, 10)
'0313102310'
>>> mercantile.quadkey_to_tile('0313102310')
Tile(x=486, y=332, z=10)

Also in mercantile are functions to traverse the tile stack.

.. code-block:: pycon

>>> mercantile.parent(486, 332, 10)
Tile(x=243, y=166, z=9)
>>> mercantile.children(mercantile.parent(486, 332, 10))
[Tile(x=486, y=332, z=10), Tile(x=487, y=332, z=10), Tile(x=487, y=333, z=10), Tile(x=486, y=333, z=10)]

Named tuples are used to represent tiles, coordinates, and bounding boxes.

Mercantile CLI

Mercantile's command line interface, named "mercantile", has commands for
getting the shapes of Web Mercator tiles as GeoJSON and getting the tiles
that intersect with a GeoJSON bounding box.

.. code-block:: console

$ mercantile --help
Usage: mercantile [OPTIONS] COMMAND [ARGS]...

  Command line interface for the Mercantile Python package.

Options:
  -v, --verbose  Increase verbosity.
  -q, --quiet    Decrease verbosity.
  --version      Show the version and exit.
  --help         Show this message and exit.

Commands:
  bounding-tile  Print the bounding tile of a lng/lat point, bounding box, or
				 GeoJSON objects.
  children       Print the children of the tile.
  neighbors      Print the neighbors of the tile.
  parent         Print the parent tile.
  quadkey        Convert to/from quadkeys.
  shapes         Print the shapes of tiles as GeoJSON.
  tiles          Print tiles that overlap or contain a lng/lat point, bounding
				 box, or GeoJSON objects.

See Also

supermercado <https://github.com/mapbox/supermercado>__ is another python lib
with added tile logic functionality (union tile shapes, find edge tiles, and
find tile intersections for complex geometries).

node-sphericalmercator <https://github.com/mapbox/node-sphericalmercator>__
provides many of the same features for Node.

tilebelt <https://github.com/mapbox/tilebelt>__ has some of the GeoJSON
features as mercantile and a few more (tile parents, quadkey).

morecantile <https://github.com/developmentseed/morecantile>__ is like mercantile,
but with support for other TileMatrixSet grids.
