OpenRouteService plugin for Quantum GIS available now
The “OSM Route” plugin is published in the offical QGIS repository and can be simply installed via the QGIS plugin manager (please enable experimental plugins within QGIS, see screenshot below, then search for OSM Route within the plugin library).
Besides the possibility to route on OpenStreeMap road networks with any given mode of transport (car,bike, pedestrian), the plugin also offers the Accessibility Analysis feature, showing you how far you can travel in a given time. All results are stored as a QGIS layer and can therefore be easily converted into any other format (e.g. shapefiles). Please test the plugin and report any issues here. Enjoy!
