Isochrone Map
An Isochrone Map draws travel-time zones — the area reachable within 5, 10, or 30 minutes from a point — for driving, cycling, walking, or public transit. It answers "how far can I get from here" and "who can reach this location."
In the app it is listed as Travel Time Map. Place up to 5 starting points, choose a travel mode, and pick preset bands or type your own — 20 minutes, say — and Mapji renders the reachability polygons over your styled base map. Switch on schools and stations to mark them on the map alongside the zones.
What you can do
- Driving, walking, cycling & transit
- Preset or custom time & distance bands
- Overlay on any base map

Isochrone Map FAQ
What's the difference between an isochrone and an isodistance map?
An isochrone bands the area you can reach within a given travel time; an isodistance bands it by distance travelled along the network. Mapji draws either — pick time or distance when you set the ranges.
Which travel modes are supported?
Walking, cycling, driving, and public transit. Each produces a genuinely different catchment shape — a transit polygon often arrives as disconnected islands around stops, while a driving one stretches along fast roads. You can band by travel time or by distance travelled along the network.
