PosTile
Fast Mapbox Vector Tile Server
Features
- serve Mapbox Vector Tiles from a PostGIS backend
- can read TM2 file data sources with postgis
- can serve PostGIS layers individually
- handle on-the-fly reprojection to web mercator projection (only for single layers, not tm2 sources)
- Connection pooling and asynchronous requests thanks to asyncpg
- tested with openmaptiles vector tile schema
Requires
- features stored with PostGIS >= 2.4.0
Installation
Python 3.6 is required to run Postile
pip install cython
pip install -e .
postile --help
Using a Docker container
Start Postile with:
docker run --network host oslandia/postile postile --help
Example of serving postgis layers individually
postile --pguser **** --pgpassword **** --pgdatabase mydb --pghost localhost --listen-port 8080 --cors
Then layer boundaries
can be served with:
http://localhost:8080/boundaries/z/x/y.pbf?fields=id,name
fields
is optional, and when absent only geometries are encoded in the vector tile.
For a concrete example using OpenMapTiles schema see this tutorial
