MavenĮmbed GraphHopper with OpenStreetMap support into your Java application via the following snippet: GraphHopper is written in Java and officially runs on Linux, Mac OS X and Windows. Other map data will need a custom import procedure, see e.g. OpenStreetMap, GraphHopper wouldn't be possible at all. OpenStreetMap is directly supported by GraphHopper. We suggest that you contribute back your changes, as GraphHopper evolves fast,īut of course this is not necessary. We chose the Apache License to make it easy for you to embed GraphHopper in your products, even closed source. Read more about the technical details here. If the preparations exist you can switch between all modes at request time. Order of magnitude faster than the flexible mode and uses less RAM for one request. integrating traffic data.įurthermore, this hybrid mode is slower than the speed mode, but it is an Then there is the hybrid mode which also requires more time and memory for the preparation,īut it is much more flexible regarding changing properties per request or e.g. However, only predefined vehicle profiles are possible and this additional CH preparation is time and resource consuming. The speed mode comes with very fast and lightweight (less RAM) responses and it does not use heuristics. We call this speed mode without this CH preparation, we call it flexible mode. GraphHopper supports several routing algorithms, such as There is the map matching subproject to snap GPX traces to the road. To support these high precision reachability approaches there is the /sptĮndpoint (shortest path tree). Use isochrones to calculate and visualize the reachable area for a certain travel mode Isochrone Web API Seeĭemo and this pull request of the iOS fork including a demo for iOS. Offline routing is no longer officially supported but should still work. There is a web service that can be consumed by our navigation Android client. All this is available for free, via encrypted connections and from German servers for a nice and private route planning experience! Public Transit Additionally to the GraphHopper Directions API, map tiles from various providers are used The photon project is also supported by the GraphHopper GmbH. GraphHopper Maps uses the commercial offering the GraphHopper Directions API under the hood, which provides the Routing API (based on this routing engine), a Route Optimization API based on jsprit, a fast Matrix API and an address search based on photon. To see the road routing feature of GraphHopper in action please go to GraphHopper Maps. The Docker images created by the community from the master branch can be found here the elevation guide and the deployment guide. You should be able to right click on the map to create a route. Java = -jar *.jar server config-example.ymlĪfter a while you see a log message with 'Server - Started', then go to and ![]() To install the GraphHopper Maps UI and the web service locally you need a JVM (>= Java 8) and do: See our changelog file for Java API Changes.To get started you can try GraphHopper Maps, read through our documentation and install the GraphHopper Web Service locally. We even have good first issues to get started. Like finding and fixing bugs and improving our documentation or translations! Read through how to contribute for information on topics Please do not use our issue section for questions :) Contribute ![]() You can also search Stackoverflow for answers. QuestionsĪll questions go to our forum where we also have subsections specially for developers, mobile usage, and our map matching component. Let us know your problems, use cases or just say hello. We have an open community and welcome everyone. GraphHopper uses OpenStreetMap and GTFS data by default and it can import other data sources too. Beyond this "A-to-B" routing it supports "snap to road", Isochrone calculation, mobile navigation and more. It can be used as a Java library or standalone web server to calculate the distance, time, turn-by-turn instructions and many road attributes for a route between two or more points. GraphHopper is a fast and memory-efficient routing engine released under Apache License 2.0. ![]()
