The Isochrone API creates reachable areas based on a maximum travel time. These reachable shapes are sometimes called
catchment areas or
trade areas, and can be a single polygon or a multi-polygon.
The API supports a range of transport modes including Driving, Public Transport, Walking, and Cycling.
The Isochrone API is a RESTful API, using HTTP requests for access.
- GET - for simple requests using basic parameters only
- POST - for more complex requests using advanced parameters
