s2sphere

s2sphere is a Python implementation of a part of Google's C++ S2 Geometry Library. It provides tools for working with spherical geometry, such as mapping points and regions on a sphere to a 1D index, enabling scalable proximity searches on distributed indexes. The current version is 0.2.5, and it maintains an active release cadence, primarily via updates to its GitHub repository and PyPI package. [1, 2, 3]
