Open Infrastructure Map

This is the main repository for OpenInfraMap.

Note: the web frontend and backend were previously in separate repositories. They were merged into this repository (previously called styles) in September 2021, in order to make development easier and make it clearer where to file issues.

Web frontend

The web frontend contains the Javascript app, built by Webpack and served as static files.

Web backend

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.

Mapping

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.

The tegola.yml and layers.yml files are used to generate the Tegola config using python3 ./tegola/generate_tegola_config.py ./tegola/tegola.yml ./tegola/layers.yml > ./tegola/config.toml.

Services

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
