# OvertureMaestro

An open-source tool for reading OvertureMaps data with multiprocessing and additional Quality-of-Life features.

## What is **OvertureMaestro** 🎼🌍?

- Scalable reader for OvertureMaps data.

- Is based on top of `PyArrow`[^1].

- Saves files in the `GeoParquet`[^2] file format for easier integration with modern cloud stacks.

- Filters data based on geometry.

- Can filter data using PyArrow expressions.

- Utilizes multiprocessing for faster data download.

- Utilizes dedicated index of all features in the Overture Maps dataset to download only specific parts based on the geometry filter.

- Utilizes caching to reduce repeatable computations.

- Can be used as Python module as well as a beautiful CLI based on `Typer`[^3].
