 1. Download OSM probuf file (.pbf file) for the target region of interest. See: <https://download.geofabrik.de> or <https://download.bbbike.org/osm/planet/> and place into `./data` folder.
 2. Download Who's On First (SpatiaLite format). For planet see: <https://geocode.earth/data/whosonfirst/combined/> and <https://data.geocode.earth/wof/dist/spatial/whosonfirst-data-admin-latest.spatial.db.bz2>
