# Download Routing Segments
|
|
|
|
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
|
|
[https://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 `segments4` directory.
