This is the main repository for OpenInfraMap.

The web frontend contains the web app, written in TypeScript using Maplibre GL JS, and served as static files.

The web backend serves the stats pages, as well as some additional non-JS web endpoints. It's an async python web app built using starlette.

The mapping file controls how the OSM subset is imported with imposm3. It's generated from the files in mapping by calling python3 ./mapping/main.py > ./mapping.json.

Changes to the mapping require a re-import of the OpenStreetMap database, which takes a while and is currently done very irregularly.

I will generally not make any changes to the mapping files unless I'm ready to run a re-import, so if you'd like some changes made to those, please raise an issue rather than a PR.

Map tiles are served with Tegola. There's a YAML-based language which generates the Tegola config, from the tegola.yml and layers.yml files:

python3 ./tegola/generate_tegola_config.py ./tegola/tegola.yml ./tegola/layers.yml > ./tegola/config.toml

Imposm runs as a service with the -expiretiles-dir option:

/usr/local/bin/imposm run -config /home/osm/imposm.json -expiretiles-dir /home/osm/imposm-expire

The low-zoom layers are seeded daily with:

/usr/local/bin/tegola cache seed --bounds="-180,-85.0511,180,85.0511" --min-zoom 2 --max-zoom 6 --overwrite --config /home/osm/styles/tegola/config.toml

Invalidated tiles are removed every minute:

/usr/bin/python3 /home/osm/styles/tegola/expire.py /home/osm/imposm-expire

Materialised views are updated every 10 minutes with:

/usr/bin/psql -h 10.43.18.68 osm < /home/osm/styles/refresh_matviews.sql  > /dev/null

Old diff files are removed periodically with:

/usr/bin/find /home/osm/imposm_diff -type f -mtime +14 -exec rm {} \; > /dev/null
