BRouter
=======
BRouter is a configurable OSM offline router with elevation awareness, Java + Android. Designed to be multi-modal with a particular emphasis on bicycle routing.
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
For more infos see [http://brouter.de/brouter](http://brouter.de/brouter).
## BRouter on Android
You can install the BRouter app on your Android device from
[F-Droid](https://f-droid.org/packages/btools.routingapp) or [Google Play
Store](https://play.google.com/store/apps/details?id=btools.routingapp). You
can also [build BRouter](#build-and-install) yourself. You can find detailed
documentation of the BRouter Android app in
[`misc/readmes/readme.txt`](misc/readmes/readme.txt).

### Android with Locus
## Build and Install
You can use BRouter as the offline routing engine for [Locus
Map](https://www.locusmap.eu/) on your Android device. This is currently the
most featureful and maintained solutions for using BRouter on your Android
device.
Compile with (Java 6!):
> mvn clean install -Dandroid.sdk.path=<your-sdk-path>
To skip building for Android, add ``-pl '!brouter-routing-app'``.
Next, download one or more [data file(s)](http://brouter.de/brouter/segments4/) (rd5) into the ``misc/segments4`` directory.
## Run
On Linux:
> ./misc/scripts/standalone/server.sh
On Windows (using Bash):
> ./misc/scripts/standalone/server.sh
On Windows (using CMD):
> misc\scripts\standalone\server.cmd
A full documentation on how to set this up is available at
[https://www.locusmap.eu/locus-map-can-navigate-offline/](https://www.locusmap.eu/locus-map-can-navigate-offline/).

================
### Android with OSMAnd
* https://github.com/nrenner/brouter-web
* https://github.com/poutnikl/Brouter-profiles/wiki
Alternatively, you can also use BRouter as the offline routing engine for
[OSMAnd](https://osmand.net/) on your Android device.
A full documentation on how to set this up is available at
[`misc/readmes/osmand/README.md`](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](https://www.openstreetmap.org/) 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/](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](https://download.geofabrik.de/)).
More documentation of this is available in the
[`misc/readmes/mapcreation.md`](misc/readmes/mapcreation.md) file.
### 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`](brouter-server/src/main/java/btools/server/request/ServerHandler.java)
file.
## Documentation
More documentation is available in the [`misc/readmes`](misc/readmes) folder.
## Related Projects
* [nrenner/BRouter-web](https://github.com/nrenner/brouter-web), a web interface on
top of the BRouter HTTP server. An online instance is available at
[http://brouter.de/brouter-web/](http://brouter.de/brouter-web/).

Build your own BRouter segments files
=====================================
BRouter uses its own data format (`.rd5` files), split in tiles of 5 x 5
in latitude and longitude. You can download the official segment files (weekly
built) from [brouter.de](http://brouter.de/brouter/segments4/) but you can
also build them yourself from an OSM dump.
## Build the pbfparser
First, there are two file formats available to download OSM data: `bzip`-ed
XML files (very large) and `.pbf`
([Protobuf](https://github.com/protocolbuffers/protobuf) format) which is much
more efficient. If you want to use the latter one, you will have to build the
`pbfparser` (located in `misc/pbfparser` first):
* Download [the latest
version](https://bretth.dev.openstreetmap.org/osmosis-build/osmosis-latest.zip)
of [Osmosis](https://wiki.openstreetmap.org/wiki/Osmosis) and unzip it
somewhere.
* Copy the `lib/default/protobuf-java-*.jar` and
`lib/default/osmosis-osm-binary-*.jar` files from the unzipped Osmosis
archive to `misc/pbfparser/protobuf.jar` and `misc/pbfparser/osmosis.jar`.
* Build BRouter and copy
`brouter-server/target/brouter-server-*-jar-with-dependencies.jar` to
`misc/pbfparser/brouter.jar`.
* You can build the `pbfparser` using, in the `misc/pbfparser/`
folder,
```
javac -d . -cp "brouter.jar:protobuf.jar:osmosis.jar" *.java
```
* Finally, you can build a `jar` file from these files using
```
jar cf pbfparser.jar btools/**/*.class
```
_Note:_ If the `jar` file is not properly created, everything else will seem
to work normally but there will not be any data extracted from the OSM data
dump. You can check what is actually inside the built `jar` file using
`jar tf pbfparser.jar`.
## Run the map creation script
If you want to have elevation information in the generated segments files, you
should download the required [SRTM
files](https://cgiarcsi.community/data/srtm-90m-digital-elevation-database-v4-1/)
and set the `SRTM_PATH` variable when running the `process_pbf_planet.sh`
script.
Any flavor of the 90m SRTM database should be working, but the one used by the
official BRouter segments files are the ones provided by
[CGIAR](https://cgiarcsi.community/data/srtm-90m-digital-elevation-database-v4-1/).
If you are working with rather small geographical extracts, you can download
tiles manually using [this
interface](http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp) (use the
"ArcInfo ASCII" format), instead of having to ask for an access for bulk
download of data. There is no need to unzip the downloaded files, the
`process_pbf_planet.sh` script expects a folder with all the ZIP files inside
and will manage it.
Note that if you don't have the SRTM data available, the segments files will
still be generated without any issue (but they will miss the elevation data).
If you are not sure which SRTM files you have to download, you can run the
script once and it will log all the SRTM files it is looking for.
You can now run the `misc/scripts/mapcreation/process_pbf_planet.sh` script to
build the segments. Have a look at the variables defined at the beginning of
the files and overwrite them according to your needs. By default, the script
will download the latest full planet dump from
[planet.osm.org](https://planet.osm.org/). You can also download a
geographical extract provided by [Geofabrik](https://download.geofabrik.de/)
and set the `PLANET_FILE` variable to point to it.
_Note:_ It is possible that you encounter an error complaining about not being
able to run `bash^M` on Linux/Mac OS. You can fix this one by running
`sed -i -e 's/\r$//' process_pbf_planet.sh`.

Using BRouter on Android with OSMAnd
====================================
BRouter integration in OSMAnd changed a lot during the summer of 2019. This
guide assumes you are using the BRouter Android app in version 1.5.0 or higher
as well as OSMAnd in version 3.4 or higher.
## Installing BRouter app on your Android device
First, install the BRouter app on your Android device from
[F-Droid](https://f-droid.org/packages/btools.routingapp) or [Google Play
Store](https://play.google.com/store/apps/details?id=btools.routingapp). You
can also build the BRouter Android app yourself.
<a href="https://f-droid.org/packages/btools.routingapp" target="_blank">
<img src="https://f-droid.org/badge/get-it-on.png" alt="Get it on F-Droid" height="90"/></a>
<a href="https://play.google.com/store/apps/details?id=btools.routingapp" target="_blank">
<img src="https://play.google.com/intl/en_us/badges/images/generic/en-play-badge.png" alt="Get it on Google Play" height="90"/></a>
## Downloading BRouter segments
Then, launch the BRouter app and choose "Download Manager". Zoom in and select
the areas you want to route in. Then click "Start Download" and BRouter will
start downloading the [segments](http://brouter.de/brouter/segments4/) files
for the selected areas.
<img src="./brouter-main.png" alt="Main menu of BRouter android app"/>
<img src="./brouter-grid.png" alt="Grid selection of segments to download"/>
Note that you will have to repeat this step periodically, whenever you want to have an
updated version of the OSM data used for the routing.
## Selecting profiles to use
Once this is done, start again the BRouter app and choose the "BRouter App"
entry on the main menu. Select the routing profile you want to use and click
"Server-Mode". Then, tick the boxes for the routing modes you want to use this
profile for. You can use two different profiles per transportation mode, which
will be mapped to the "shortest" and "fastest" presets (these are just
labelling) in OSMAnd.
<img src="./brouter-profiles.png" alt="Profiles selection"/>
<img src="./brouter-profiles-summary.png" alt="Profiles selection summary"/>
## Configure OSMAnd to make use of BRouter offline navigation
You can now create an "Application profile" in OSMAnd which will be using
BRouter for offline routing. Go to Settings -> Application profiles -> Add and
create a new profile based on the base profile of your choice (cycling here,
for bicycle routing), with a custom name of your choice ("BRouter" on the
screenshot below) and making use of "BRouter (offline)" for navigation.
<img src="./brouter-osmand.png" alt="BRouter configuration in OSMAnd
application profiles"/>
The BRouter app should be launched before OSMAnd for this specific entry to
appear in OSMAnd. Therefore, if you cannot find "BRouter (offline)" navigation
option, you should force quit OSMAnd and restart it.
