isochrone
Calculate accessible areas around a location using time or distance constraints with isochrone contours. Ideal for visualizing travel range by foot, car, bike, or other modes, returning GeoJSON polygons for mapping.
Instructions
Generate isochrone contours showing areas reachable within specified time or distance constraints from a single location. Returns GeoJSON polygons representing the reachable areas.
