Travel time (isochrones)

A travel-time layer — also called an isochrone — shows how far you can reach from a location within a given time or distance. It answers questions like "which customers are within a 15-minute drive of each store?"

As a layer

Add a Travel time layer to turn every row in a data source into an origin. For each origin, Icon Map draws the area reachable within your chosen limit. You can set:

  • Mode — car, walking, or cycling.
  • Limit type — time (e.g. 15 minutes) or distance (e.g. 5 km).
  • Styling — fill and outline for the catchment areas.

Travel times are estimated from road-class speeds. They give a realistic reachability model but do not use live traffic.

As a tool

You can also measure travel time interactively: use the Travel time map control (or the drive-time mode of the Selection tools) to click anywhere on the map and instantly see the reachable area, with a live preview as you move.

Saving results

Catchment areas can be saved to your OneLake as GeoJSON, so you can reuse them in other maps, layers, or analysis.
