Where the maps
come from

CityWalker is built on open data. This page credits every source the app uses: the streets you walk, the map underneath them, and the outlines of the 193 cities I've split into regions.

Streets and map

Every street CityWalker tracks, in every city, comes from OpenStreetMap.

Region outlines

Large cities are split into regions so you can download one neighbourhood at a time. The outlines come from OpenStreetMap or from official open data, credited below.

I've changed these outlines: they're simplified to within 2 metres, and in many cities small areas are merged into larger regions or renamed. The original data is available from each source.
