Construct and use OGC TileMatrixSets (TMS)

Morecantile

Construct and use map tile grids (a.k.a TileMatrixSet / TMS).

Documentation: https://developmentseed.org/morecantile/

Source Code: https://github.com/developmentseed/morecantile

---

Morecantile is like mercantile (the best tool to work with Web Mercator tile indexes), but with support for other TileMatrixSet grids.

Morecantile follows the OGC Two Dimensional Tile Matrix Set specification 2.0 found in https://docs.ogc.org/is/17-083r4/17-083r4.html

Morecantile Version	OGC Specification Version	Link
>=4.0	2.0	https://docs.ogc.org/is/17-083r4/17-083r4.html
=<3.0	1.0	http://docs.opengeospatial.org/is/17-083r2/17-083r2.html

Install

$ python -m pip install -U pip
$ python -m pip install morecantile

# Or install from source:
$ python -m pip install -U pip

Usage

import morecantile

tms = morecantile.tms.get("WebMercatorQuad")

# Get TMS bounding box
print(tms.xy_bbox)
>>> BoundingBox(
    left=-20037508.342789244,
    bottom=-20037508.34278919,
    right=20037508.34278919,
    top=20037508.342789244,
)

# Get the bounds for tile Z=4, X=10, Y=10 in the TMS's CRS (e.g epsg:3857)
print(tms.xy_bounds(morecantile.Tile(10, 10, 4)))
>>> BoundingBox(
    left=5009377.085697308,
    bottom=-7514065.628545959,
    right=7514065.628545959,
    top=-5009377.085697308,
)

# Get the bounds for tile Z=4, X=10, Y=10 in Geographic CRS (e.g epsg:4326)
print(tms.bounds(morecantile.Tile(10, 10, 4)))
>>> BoundingBox(
    left=44.999999999999964,
    bottom=-55.776573018667634,
    right=67.4999999999999,
