Build segment 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 but you can
also build them yourself from an OSM dump (e.g. planet or GeoFabrik
extract)
If you want to have elevation information in the generated segments files, you
should download the required SRTM
files
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.
If you are working with rather small geographical extracts, you can download
tiles manually using this
interface (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. You can also download a
geographical extract provided by Geofabrik
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
.
