Add isochrones to your next application

Today we’re sharing a plugin to generate your own #isochrones, right in your browser. With a starting location and Mapbox access token, the plugin will calculate isochrones up to 60 minutes via driving, cycling, or walking.

The page OpenRouteService.org is a very easy to use website which provides routing from A to B via C. It also allows to choose between different routing types for trucks, pedestrians or bicycles and isochrone analyses based on time and distance. In this article I would like to show you, how to embed the OpenRouteSevrice API into your very own Leaflet based webmap.

A new kind of map: it’s about time

“In this time map, we preserve the direction of each point, relative to the user. But the visual distance from that center point is determined by the time it takes to get there, whether driving, biking, or on foot.”

What these data are and what they are not

Accessibility maps are made for a specific purpose and they cannot be used as a generic dataset to represent “the” accessibility for a given study area. The data described and presented here were used to create an urban/rural population gradient around large cities of 50,000 or more people. The assumptions made in the generation of this accessibility map can be found in the description and data sources links on the left. If these assumptions sound reasonable for your requirements then the data are available for download. If, however, the assumptions do not match your requirements then you can use the information in these pages as well as the software and external links to create your own accessibility model.
