Faster Route Calculation The route calculation for the flexible mode got up to 30% faster! Great rework from @easbar (#2571 and #2600). And […]

OpenStreetMap (OSM) is a free digital map of the world that is created and maintained by millions of users. Among many other things it includes detailed information about every possible type of road, ranging from narrow hiking trails in the mountains to the biggest motorways. Using the open source GraphHopper routing engine you can easily […]
