S2 Geometry | S2Geometry Welcome to the S2 Geometry Library! A unique feature of the S2 library is that unlike traditional geographic information systems, which represent data as flat two-dimensional projections (similar to an atlas), the S2 library represents all data on a three-dimensional sphere (similar to a globe)
Computational geometry and spatial indexing on the sphere Unlike many geometry libraries, S2 is primarily designed to work with spherical geometry, i e , shapes drawn on a sphere rather than on a planar 2D map This makes it especially suitable for working with geographic data

Overview | S2Geometry S2 achieves this goal using a combination of techniques from computational geometry, including conservative error bounds, exact geometric predicates, and snap rounding
google s2geometry | DeepWiki Unlike traditional geometry libraries that work with flat (planar) coordinates, S2 is built specifically for spherical geometry, making it ideal for geographic applications, global positioning, mapping, and any situation requiring accurate representation of Earth-based shapes
