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].
