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
