October 2016 - GraphHopper Directions API

Graphhopper Directions API News October

A long silence for a young company can mean many different things. In our case it only means that we further concentrate on making our products better! We are very happy to improve the GraphHopper Directions API every week and keep you up to date with this newsletter.

We improved the Route Optimization API in various ways:

We added a new maximum distance feature
We tuned our algorithms to solve large scale problems (>> 50 vehicles and >> 300 locations) significantly: we are now much faster and even better.
Now it is possible to minimize vehicles, see the documentation
The API supports driving time dependent break scheduling
You can use custom cost matrices e.g. to support indoor route optimization or custom ETAs
The optimization response can now include route geometries
We updated our tutorials
More auto generated API clients are added and tested

We released version 0.8 of our open source routing engine coming now with 39 translations, which are directly available in the Routing API.

A new Map Matching API was released which does an automated ‘snap to road’ useful to improve recorded GPS traces:

A lot more is happening in the GraphHopper space: we had our first, very own GraphHopper meeting, spoke at IAA, FOSSGIS, … and reached a new star record for our open source projects (sum is over 1400!).

You can now follow us not only on Twitter but also on LinkedIn and Facebook. Or visit us at WhereCamp Berlin or at Startup-DemoNight in Munich in real life.

Over the last months we were very happy to welcome dozens of new customers, bigger and smaller – hello again 🙂 !

If you have questions or problems, do not hesitate to contact us!

Happy Routing!

GraphHopper Routing Engine 0.8 Released

We are proud to release version 0.8 of our open source GraphHopper routing engine! Here is the polished snap-to-road feature in two screenshots:

A big thanks goes to all of our contributors and translators!

To become a contributor see our contributing guidelines and e.g. the good first issues. Read here to see how to become a sponsor and how to benefit from our expertise or donate us.

Here are the highlights for GraphHopper 0.8:

the new map matching algorithm based on hidden markov chains is finally integrated and gives us a big quality improvement, thanks to @michaz (GraphHopper) and @stefanholder (BMW Car IT). This feature was already deployed 2 months ago in our GraphHopper Directions API. Some improvements were done by @kodonnell.
the osm import module is split from the core #450 making Android and iOS integration cleaner
there is a new overlay module #781 allowing you to specify GeoJSON at import time to change properties like access and speed of the routing graph
new ‘more standard’ code formatting for all repositories #770
many UI fixes like upgrading to leaflet 1.0, thanks to @fbonzon (Bikewithme)
updated the iOS port, thanks to Calin @clns
travis build enhancements like running against jdk9 and deploying snapshots #806, thanks to @mprins
a new ‘on-demand’ weighting with a new data encoder #730
elevation interpolation in tunnels&bridges #713, thanks to @highsource (DB Systel)
fixing time calculation for turn costs #393
a new short_fastest weighting #747
Several updates to Android build/sample from @devemux86 (talent)
several bug fixes (incl. three major)

The changelog is here – please read about the necessary changes to your config.properties and/or your Java code. Dowload the new version here. As the documentation has slightly improved we’d like your input here as well.

In the next release we expect bigger changes to come like one top secret 😉 and this exciting work from @devemux86 which continues the work from VTM (OpenScienceMap) and has OpenGL support, allows map rotation, iOS support and more, while keeping compatibility with the Mapsforge file format.

And if you like OpenStreetMap as we do, consider supporting them via money.

Happy routing!
