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.
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.
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/.
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.
To compile the BRouter Android app, the Android SDK path must first be set in a file called local.properties in the main folder:
sdk.dir=<your/android/sdk/path>
Build BRouter with the Android app (if Android SDK path is set):
./gradlew clean build
Build BRouter without the Android app:
./gradlew clean build -x :brouter-routing-app:build
Build JAR file for server and map creator with all dependent classes:
./gradlew clean build fatJar # places JAR file in brouter-server/build/libs/
Build ZIP file for distribution with readmes, profiles, APK and JAR:
./gradlew distZip # places ZIP file in brouter-server/build/distributions/
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.
Segments files from the whole planet are generated weekly at https://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.
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.
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.
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.
More documentation is available in the misc/readmes folder.
