S2 Geometry Library
A C++ library for computational geometry and spatial indexing on the sphere, designed for geographic data.
What is S2 Geometry Library?
S2 Geometry is a C++ library for computational geometry and spatial indexing specifically designed for spherical geometry. It provides tools to manipulate geometric shapes on a sphere, making it ideal for working with geographic data where Earth's curvature is important. The library solves problems like efficient spatial queries and accurate geometric calculations on a spherical surface.
Developers and researchers working with geographic data, mapping applications, or any spatial analysis requiring spherical geometry. This includes GIS engineers, data scientists handling location data, and backend developers building geospatial services.
Developers choose S2 Geometry because it's specifically designed for spherical geometry—unlike many planar geometry libraries—ensuring accuracy for geographic applications. Its efficient spatial indexing and cross-language support (C++, Python, Go, Java) make it a versatile choice for high-performance geospatial computations.
