Tilekiln is a set of command-line utilities to generate and serve Mapbox Vector Tiles (MVTs). It generates asynchronously with tilekiln-generate and serves them with tilekiln-serve.

Generation relies on the standard method of a PostgreSQL + PostGIS server as a data source, and ST_AsMVT to serialize the MVTs.

The target use-case is vector tiles for OpenStreetMap Carto on openstreetmap.org, a worldwide complex basemap under high load.

For local development

python3 -m venv venv
. venv/bin/activate
pip install --editable .

Tilekiln requires a PostGIS database with data loaded to generate vector tiles, saving them to a filesystem or object store supported by PyFilesystem.

OpenStreetMap Carto's directions are a good starting place for loading OpenStreetMap data into a PostGIS database.

• PostgreSQL 9.5+
• PostGIS 2.4+, 3.0 is strongly recommended
• Python 3.6+

This reads a config file and produces a tilejson file, frequently used in software consuming vector tiles.

This reads a config file and generates vector tiles, saving them to the object store

Usage: tilekiln-generate area [OPTIONS] CONFIG STORAGE

  Generates tiles for an area

Options:
  -d, --dbname TEXT
  -h, --host TEXT
  -p, --port TEXT
  -U, --username TEXT
  -c, --connections INTEGER
  -s, --chunk-size INTEGER
  -z, --min-zoom INTEGER
  -Z, --max-zoom INTEGER
  --help                     Show this message and exit.

Test code with python setup.py test.

All code should be formatted according to flake8. Check this with flake8 tilekiln tests
