Valhalla Isochrone

The Isochrone service provides insight into travel at an individual level and en masse, whether by car, foot, bike, or public transit. Powered by Mapzen’s Turn-by-Turn service and Transitland data, the isochrone service gives you the ability to analyze transportation options with options to customize time cutoffs, multiple geometry formats, and more.


  • Customize your isochrone results. Specify the number and colors of contours, and whether the returned geometries are lines or polygons.
  • Use different costing models. Set the travel mode to analyze travel times by car, foot, bike, and public transit.
  • Examine transit access. Use our global transit database to build isochrones any time of day, for trains, buses and other public transportation.
