Built on open data

Nightjar stands on the shoulders of open communities. The maps, the routing, the terrain and the search all come from open data and open-source software. Here’s who makes it possible, and how we give back.

The projects behind Nightjar

OpenStreetMap

A free, community-built map of the whole world, edited by millions of people. It gives Nightjar its streets, paths, addresses, places and buildings.

Overture Maps Foundation

An open map dataset stewarded by a foundation of major technology companies. Nightjar uses it to enrich places and points of interest alongside OpenStreetMap.

Open data, under the ODbL and CDLA-Permissive licences.

Wikidata

A free, structured knowledge base run by the Wikimedia community. It supplies extra detail and names in many languages for the places you search.

Released into the public domain (Creative Commons CC0).

OpenMapTiles

An open schema and toolchain for turning OpenStreetMap data into fast, styleable vector maps. Nightjar’s map rendering builds on its work.

Open-source schema and tools; underlying map data from OpenStreetMap (ODbL).

Valhalla

An open-source routing engine that works entirely offline. It powers Nightjar’s turn-by-turn directions, multi-stop trips, travel-time ranges and snapping messy GPS tracks to roads.

Open-source software, maintained by the Valhalla community.

Copernicus DEM

The European Union’s global digital elevation model. It powers Nightjar’s 3D terrain, contour lines and hillshading.

Giving back

Nightjar wouldn’t exist without these communities, and we don’t take that for granted. We’re committed to giving back to the projects that power it, and we encourage you to support them directly too. Most of them welcome donations and contributions on their own websites.
