This repository is a collection of recipies to make a few large-ish data sets available in [GeoParquet](https://github.com/opengeospatial/geoparquet)/[GeoArrow](https://github.com/geoarrow/geoarrow) format to facilitate testing, prototyping, and benchmarking implementations.

## [Examples](example#readme)
