S2 is a library for spherical geometry written primarily by Eric Veach:

• Designed to have good performance on large geographic datasets.
• Organized as a toolkit with various layers, that gives clients as much control as possible.
• Works exclusively with spherical projections.
• API available in C++, Go, Java and Python.
• Supports Linux and MacOSX.

An open-source tool for reading OpenStreetMap PBF files using DuckDB.

• Scalable reader for OpenStreetMap ProtoBuffer (pbf) files.
• Is based on top of DuckDB1 with its Spatial2 extension.
• Saves files in the GeoParquet3 file format for easier integration with modern cloud stacks.
• Utilizes multithreading unlike GDAL that works in a single thread only.
• Can filter data based on geometry without the need for ogr2ogr clipping before operation.
• Can filter data based on OSM tags.
• Utilizes caching to reduce repeatable computations.
• Can be used as Python module as well as a beautiful CLI based on Typer4.
