The isochrone layer displays travel times to a point on the map. Modes of transport include Walking, Bus and Car plus others.
To add an isochrone layer
On a project map,
- Select Add layer
- Select Isochrone from the list. You can filter the list by typing iso or isochrone into the text field. Once selected the isochrone will be added to the map
The isochrone will default to a point on the map. It may take longer than other layers to load as it calculates journey times.
Once added Travel settings and Appearance can be updated.
- Start point: see To move the start point (below)
- Mode of transport: transport modes with some combinations. Faster transport will lead to a larger isochone displayed on the map
- Transit period: isochrones take into account local road traffic and bus schedules when calculating journey times. If you want your journey to include the use of buses, choose a relevant transit period
- Max cost: the maximum time for the displayed journeys. Places that take longer to travel to are not included in the isochrone
- Interval: the isochrone is displayed as coloured bands. Each band is a journey time interval. These can be made more granular or broader depending on how you want the journey times presented
- Isochrone sharpness: use lower values to produce smoother, more exaggerated isochrones. Values that are too high can create patchy, “sharp” isochrones
To move the start point
With the Isochrone layer selected,
- Under Travel settings, Start point, select Click map
- Click on the map to place the start point, the coordinates and isochrone will update
The start point can also be updated by dragging it to another point on the map.
Coordinates can be entered directly. The field order is: Longitude, Latitude.
