bagkit
A toolkit for the Dutch register of addresses and buildings (BAG). Convert to SQLite, CSV and Parquet. Address lookup via HTTP.
Writes SQLite, Parquet or CSV
One table per object type, or one row per address with its names and coordinates. Convert only the object types you need. SQLite output is a GeoPackage, Parquet is GeoParquet.
Looks up addresses
Find an address by postcode and house number, or the addresses nearest to a coordinate, with
bagkit query or over HTTP with bagkit serve.
Exposes a Rust library
The bagkit command is built on a crate you can use directly: stream typed voorkomens into your
own code, or write any of the outputs from it.
