BRouter does only the plain route-calculation and does not display a map or the calculated route on it's own and therefore works only together with a Map Application. There are two different methods for the interfacing between BRouter and the Map application: BRouter offers a service interface that is called by the map application without a need to start the BRouter-App. This way, BRouter is a routing service very much like an online routing service, including dynamic recalculations if you get off the track. The other mode of operation is to start the BRouter-App and use waypoints from the map application's waypoint database to define your route. The calculated route is then written as a GPX file (including the elevation profile) to the map-application's tracks directory.

Some popular map apps support both the service interface and the interface via the wayoint database in their current versions available on Google Play.

The service interface uses a timeout of 60s, limiting it's use to distances of about 50km, but using the BRouter App you are able to calculate much longer distances. But even long-distance tracks can be followed via the service interface (including dynamic recalculations). This is done by pre-calculating a route for your destination once using the BRouter App and assigning it to a routing mode via the "Server-Mode" Button. This feature is called "timeout-free recalculations".

The route calculation, no matter if via the service interface or via the BRouter App, also considers nogo areas that can be defined as waypoints with a special naming convention (e.g. "nogo200" for 200m radius). This way it is possible to account for actual obstacles, but this feature can also be used to enforce personal preferences.

BRouter contains a download manager that assists downloading the required routing data files.The download manager is called on the first start of the app, and later on it is offered if internet access is available.

The mapping from one of the 6 routing modes (car/bike/foot * fast/short), that are used traditionally by routing services, and BRouter's concept of fully configurable routing profiles get's the following default mapping after the installation of BRouter:

car-fast -> car-test

car-short -> moped

bike-fast -> fastbike

bike-short -> trekking

foot-fast -> shortest

foot-short -> shortest

This mapping, however, can by changed anytime via the "Server-Mode" Button of the BRouter App. But also the routing profile definitions can be changed or new ones can be created.

Routing for cars is is currently available only in an experimental state ("car-test") and is not recommend. For example, turn-restriction are not taken into account.

Introduction

BRouter is an open-source routing and navigation application designed for cyclists, hikers, and other outdoor enthusiasts. It offers a comprehensive suite of features for planning and executing journeys, including detailed routing, turn-by-turn navigation, and elevation profiles.

Routing Engine

BRouter's routing engine is renowned for its accuracy and efficiency. It utilizes a combination of open-source routing data and user-contributed information to generate optimal routes tailored to the user's preferences. The engine supports various routing profiles, allowing users to customize their routes based on factors such as distance, elevation gain, and surface type.

Navigation

BRouter provides detailed turn-by-turn navigation, ensuring users stay on track during their journeys. The app's intuitive interface displays clear instructions, estimated arrival times, and distance to the next turn. It also features an offline navigation mode, enabling users to navigate even in areas with limited or no internet connectivity.

Elevation Profiles

BRouter's elevation profiles provide a graphical representation of the elevation changes along a route. This information is crucial for assessing the difficulty of a journey and planning rest stops. The app allows users to zoom in and out of the profile to examine specific sections in detail.

Map Data

BRouter integrates with various map providers, including OpenStreetMap, MapQuest, and Google Maps. This integration allows users to access a wide range of map data, including terrain, land use, and points of interest. The app also supports custom map sources, providing users with the flexibility to use their preferred maps.

Customization

BRouter offers extensive customization options, empowering users to tailor the app to their specific needs. Users can adjust settings such as routing preferences, navigation voice, and map appearance. The app also supports plugins, allowing users to add additional functionality, such as weather forecasting or trail conditions.

Community and Support

BRouter benefits from a vibrant community of users and developers. The official forum provides a platform for users to share experiences, ask questions, and contribute to the app's development. The app's open-source nature ensures that it is constantly evolving and improving based on user feedback.

Conclusion

BRouter is an indispensable tool for anyone planning or undertaking outdoor journeys. Its powerful routing engine, detailed navigation, and comprehensive features make it an ideal companion for cyclists, hikers, and other outdoor enthusiasts. The app's customization options and active community ensure that it remains a valuable resource for years to come.
