Isochrone maps show you how far you can travel from a given location in a set time. The Isochronous Application uses Google Maps to help you work out how far you can travel from any location in any amount of time.
The application allows users to select a location, a time and the mode of transport (car, on foot or by bike). The map then displays a polygon on the map showing where you could travel in the defined time.
