What you can build

  • Build a tool that takes depot and delivery coordinates, calculates a time-and-distance matrix, and exports ranked depot suggestions for each stop.
  • Build a workflow that takes candidate locations and travel-time thresholds, calculates isochrones, and outputs coverage summaries for each site.
  • Build a utility that takes recorded location samples, requests map matching, and exports matched paths alongside the original samples.
  • Build a planner that takes a start location and identified stops, requests tour optimization, and exports the proposed visit order.
  • Build a tool that takes route coordinates, samples elevation, and outputs an elevation-enriched profile for analysis.

Try this prompt

Build an end-to-end depot-assignment tool using Valhalla’s documented Python bindings or service. Accept a CSV of depot and delivery coordinates with stable IDs, preserve the input, calculate travel-time and distance candidates using a locally configured Valhalla instance, and export a ranked depot suggestion for each delivery with the values used. Validate missing or malformed coordinates, report failed calculations clearly, and include setup notes and a small test dataset.

Get started

  1. Choose a setup path

    Use the official source-build guide or the repository’s Docker README to run Valhalla locally or on your own server.

  2. Review the Python bindings

    The project documents pyvalhalla bindings for actions including routes, isochrones, and matrices. Windows support has documented functionality limits.

  3. Prepare map data

    Follow the official documentation to build input data and graph tiles. Review the data-source guidance for licensing and other requirements.

License & notes

MITValhalla is MIT-licensed; include the required copyright and license notices. The code itself does not require a paid model or API, but running a service requires compute and hosting, and preparing or maintaining map data may add costs. Third-party data or APIs may have separate costs and terms. Included test data is ODbL-licensed; check the terms for other data sources. The public demo server has fair-use expectations and rate limits, so do not assume it is suitable for production.

  • Valhalla is an engine and library, not a finished navigation interface; an adaptation must provide its own user workflow.
  • You must prepare and maintain graph data for your area or use a suitable service. The public demo server has fair-use expectations and rate limits.
  • Windows support is partial: the README lists supported modules and notes that not all functionality is fully supported.
  • MIT applies to Valhalla code; map data can have separate terms. Included test data is ODbL-licensed, and other data sources require their own review.
