geoarrow-rs

A Rust implementation of the GeoArrow specification and bindings to GeoRust algorithms for efficient spatial operations on GeoArrow memory.

This repository also includes Python bindings and JavaScript (WebAssembly) bindings, wrapping the GeoArrow memory layout and offering vectorized geometry operations.
