Overview
Valhalla is an open source routing engine and set of libraries for use with OpenStreetMap data. Besides turn-by-turn routing it includes tools for time and distance matrices, isochrones, elevation sampling, map matching and tour optimization, which is the travelling salesman problem. Its topics mention multi-modal routing and tiled data. It is written in C++ and is typically run as a service that answers routing requests.
Key features
- Routing and directions on OpenStreetMap data
- Time and distance matrix computation
- Isochrones and elevation sampling
- Map matching and tour optimization
Best for
Developers who want to self-host routing for several travel modes on OpenStreetMap data. The README asks contributors to follow its guidelines when using generative AI.
