Streams the entire WikiData database to extract a database of cities.
To build a binary, install Cargo and run cargo build --release in this repository.
A binary will be available at target/release/geo-db.
Also see ./geo-db -h for help.
To download the initial database of cities, run ./geo-db with no arguments.
This will save it to a new database at geo.db.
Note that this database will require about 5 GB of space. Downloading will use around 4 CPU cores and take 6–8 hours on a decent internet connection.
To run subsequent post-processing, run ./geo-db post.
This will take around 30 minutes and may use up to 9 GB of space.
