Releasing GraphHopper 0.4 and the GraphHopper Directions API

Today we are proud to release version 0.4 of our open source road routing engine GraphHopper. Try it out on GraphHopper Maps:

We’ve taken several months for that release, but not without a reason as the GraphHopper Directions API for business was in the works and is also released today! The Directions API is a hosted GraphHopper routing service for world wide usage, including up-to-date software and OpenStreetMap data. It also offers features not found in GraphHopper like address search (aka Geocoding) and the Route Matrix API. Sign up for free and give us feedback!

A big thanks for that 0.4 release goes to all of our contributors! This release also includes features sponsored by Geofabrik and Talent Systems – thanks a lot! Read here to see how to become a sponsor or how to benefit from our GraphHopper knowledge.

Now these are the highlights of GraphHopper 0.4:

• The flexibility mode now supports turn costs and restrictions, with big support from khuebner
• GraphHopper is able to run offline in the browser via TeaVM since 0.3 but now we can also route offline on iOS too! This iOS port was contributed by calin.
• The bidirectional A* avoids heuristical results and is now the fastest algorithm for the flexibility mode
• Via-point support for the web UI, contributed by rbraband
• Roundabout instructions, sponsored by Talent Systems
• More dynamic location lookup which gives a higher success rate and better speed
• A new routing profile motorcycle
• Now GraphHopper contains 26 translations, contributed by several volunteers, special thanks goes to Manfred and his team!
• Improved routing for pedestrians and improved elevation interpolation for the bike2 routing profile
• Important bug fixes for the Android demo, as well as moving to Android studio still preserving Eclipse and NetBeans/maven support
• Improved GPX export
• The national mapping agency for Great Britain Ordnance Survey started work to support also other data sources (not only OpenStreetMap)
• Normal algorithms can work on an already prepared graphs – i.e. speep-up and flexibility mode can be used on the same graph
• Some refactorings to the Java API were necessary, see the full changelog for more details and easier migration
• .. all in all over 40 bugs and issues fixed

Map Matching aka ‘Snap to Road’

There is now also a map matching component based on GraphHopper and released under the Apache License 2.0. This tool can be helpful if you need to track vehicles and import their GPX tracks which is helpful to “snap them to road” like e.g. allryder is using it to optimize urban transport data or attach instructions to GPX files automatically.

Read more about it here or at wikipedia.

Now have fun with GraphHopper and expect more exciting news!
