OSM routeOSM route is more or less a possibility to interact with the service behind the domain openrouteservice.org. It lets you use addresses as input for your start- and end-point as well as an address to be on the way. This information is send to the API of openrouteservice.org and the response is converted into a polyline. Additionally I am adding the points to the map as a point shapefile. At the moment it only analysis the whole route and does not separate each segment of the route.

Reachability/Service TimesBut that’s not all! Additionally to routing you can use the plugin to calculate the reachability of places in a given time period. So called isochrones. Actually the plugin does not create lines but polygons. You can choose a time (maximum 30min as stated by the API provider) and a time for given intervals. So choosing 10 as time and 2 as intervals will provide 5 polygons for each min-interval (2min, 4min, 6min, …). This will give you the great opportunities to compare different locations in their “centrality” or to choose your next flat wisely if you have the latest point shapefile of club-locations or book stores in your desired area. It works on the input address only! You can participate with any errors/issues via Github. It is available using the official plugin page of QGIS and via the “Manage and Install Plugins” dialog in QGIS. The plugin is marked as experimental ATM.
ATTENTION: The OpenRouteService.org API does allow routing only on the continents Europe, Asia, Africa and Australia. We are in contact regarding this issue.
