Top 6 spatial-indexing Open-Source Projects

  • h3

    Hexagonal hierarchical geospatial indexing system

    • Project mention: H3: Hexagonal hierarchical geospatial indexing system | news.ycombinator.com | 2024-03-11

  • s2geometry

    Computational geometry and spatial indexing on the sphere

    • Project mention: Hexagons and Hilbert Curves – The Horrors of Distributed Spatial Indices | news.ycombinator.com | 2024-03-22

    I experimented with geospatial Hilbert Curves as a Postgres extension [0] for PostGIS using the S2 [1] spherical geometry library. S2 uses a scale free cell coverage pattern that is numbered using six interlocking space filling Hilbert Curves [2].

    By having both high level (cell) and low level (cell id) geometries it was a very powerful library which allowed projection from the hilbert space into a Postgres spatial index (spgist) including various trees, like noted in this article. It appears to be still quite active in development.

  • h3-js

    h3-js provides a JavaScript version of H3, a hexagon-based geospatial indexing system.

  • h3-go

    Go bindings for H3, a hierarchical hexagonal geospatial indexing system

  • geo-assist

    Geo Assist is a spatial library to manage spatial data in-memory.

    • Project mention: I built an open-source library to manage and query your geospatial data efficiently. This approach has been tested with applications up to a scale of ~89m requests per day and worked like a charm. You can Star the repository to help it grow.
