# Isochrones

An isochrone of a location is ''a line connecting points at which a vehicle arrives at the same time'', see Wikipedia.
With the same API you can also calculate isodistances, just use the parameter distance_limit instead of time_limit`.

Some possible areas in which this API may be useful to you:

- real estate analysis
- realtors
- vehicle scheduling
- geomarketing
- reach of electric vehicles
- transport planning
- logistics (distribution and retail network planning)

See the [clients](#section/API-Clients) section in the main documentation, and [our API explorer](https://explorer.graphhopper.com/?endpoint=isochrone).
