xt

Automatically convert a stream of tile coordinates to another format

• z/x/y | z-x-y ==> [x, y, z]

• [x, y, z] ==> z/x/y | z-x-y | z?x?y -d ?

Installation

pip install xt

Or to develop:

[email protected]:mapbox/xt.git && cd xt && pip install -e '.[test]'

Tile URL to mercantile [x, y, z]

» echo https://map.s/17/20971/5051.png | xt
[20971, 50651, 17]

mercantile to z/x/y

» echo '[0, 0, 0]' | xt
0/0/0

mercantile to z-x-y

» echo '[100, 100, 100]' | xt -d -
100-100-100
