BRouter

BRouter is a configurable OSM offline router with elevation awareness, Java + Android. Designed to be multi-modal with a particular emphasis on bicycle and energy-based car routing.

For more infos see http://brouter.de/brouter.

BRouter on Android

You can install the BRouter app on your Android device from F-Droid or Google Play Store. You can also build BRouter yourself. You can find detailed documentation of the BRouter Android app in misc/readmes/readme.txt.

Get it on F-Droid Get it on Google Play

Android with Locus

You can use BRouter as the offline routing engine for Locus Map on your Android device. This is currently the most featureful and maintained solutions for using BRouter on your Android device.

A full documentation on how to set this up is available at https://www.locusmap.eu/locus-map-can-navigate-offline/.

Android with OSMAnd

Alternatively, you can also use BRouter as the offline routing engine for OSMAnd on your Android device.

A full documentation on how to set this up is available at misc/readmes/osmand/README.md.

BRouter on Windows/Linux/Mac OS

Build and Install

To compile BRouter (including the BRouter Android app), use

mvn clean install -Dandroid.sdk.path=<your-sdk-path>

If you only want to compile BRouter and the server part (skipping the Android app), use

mvn clean install -pl '!brouter-routing-app'

You can use -Dmaven.javadoc.skip=true to skip the JavaDoc processing and -DskipTests to skip running the unitary tests.

Get the required segments (data) files

Routing data files are organised as 5*5 degree files, with the filename containing the south-west corner of the square, which means:

  • You want to route near West48/North37 -> you need W50_N35.rd5
  • You want to route near East7/North47 -> you need E5_N45.rd5

These data files, called "segments" across BRouter, are generated from OpenStreetMap data and stored in a custom binary format (rd5) for improved efficiency of BRouter routing.

Download them from brouter.de

Segments files from the whole planet are generated weekly at http://brouter.de/brouter/segments4/.

You can download one or more segments files, covering the area of the planet your want to route, into the misc/segments4 directory.

Generate your own segments files

You can also generate the segments files you need directly from a planet dump of OpenStreetMap data (or a GeoFabrik extract).

More documentation of this is available in the misc/readmes/mapcreation.md file.

(Optional) Generate profile variants

This repository holds examples of BRouter profiles for many different transportation modes. Most of these can be easily customized by setting variables in the first global context of the profiles files.

An helper script is available in misc/scripts/generate_profile_variants.sh to help you quickly generate variants based on the default profiles, to create a default set of profiles covering most of the basic use cases.

Have a look at the misc/readmes/profile_developers_guide.txt for an in-depth guide on profiles edition and customization.

Run the BRouter HTTP server

Helpers scripts are provided in misc/scripts/standalone to quickly spawn a BRouter HTTP server for various platforms.

  • Linux/Mac OS: ./misc/scripts/standalone/server.sh
  • Windows (using Bash): ./misc/scripts/standalone/server.sh
  • Windows (using CMD): misc\scripts\standalone\server.cmd

The API endpoints exposed by this HTTP server are documented in the brouter-server/src/main/java/btools/server/request/ServerHandler.java file.
