Hi,
Thank you both for your reply. It help me a lot.
@Mohammed : I am very interested about all details information you can
provide.
@Patrick : Since I work for the National Mapping Agency of France, I
have no problems with commercial data sources. We have a huge database
full of geodata in all kind. Unfortunately, this data are not made for
navigation, so we studding the possibility to adapt these data to a
routing machine. OSRM can be the solution.
Thanks again, I'll let you know the results of the possibility to doing
that if you're interested.
Regards,
Romain Wieser

Hey Romain,
Mohammed already outlined the two options you have. In general I would
suggest using the second options, since producing correct `.osrm.*`
files is pretty complex and error prone. Also we don't keep that
format stable as the interplay between `osrm-extract` and
`osrm-prepare` often changes if you add new features.
You have a much better chance of translating your data to something
that looks like the OSM data model. A few things to keep in mind:
- Some importers seem to screw up the connectivity of street segments
- You need to figure out a good mapping from attributes of your source
material to OSM tags if you want to use the profiles provided by OSRM
- If your data is rather big, consider generating an OSM file in PBF
form [1] (the XML format just does not scale for
continental/planet-size data)
I think cycle.travel runs on data from Ordnance Survy. So it is
absolutely doable, but I don't think you will find any importers
(targeting OSRM) for commercial data sources as OpenSource. (most
providers require you to sign a NDA before you are allowed to even
look at the documentation...).
Best,
Patrick

Hello Wieser,
The extractor used the osmium library which can only handle osm files.
Therefore, you need to either :
1. Create your own parser that should generates 4 files (.osrm, .osrm.nodes,
.osrm.names, .osrm.timestamp*) from the input document you got (you have the
option to not use a profile file if your datatype contain weights or speed
limits of each road segment aswell as restrictions).
2. Convert your datatype to OSM 0.6 (XML/PBF or other), I think there are
too many tools that can do this, ArcGIS can, I guess, import export from the
most commonly used geographical data.
* I can send you details information about the structure of these files as
well as datatypes and methods to write/read them.
I hope this answer help you.
Good luck.
Best regards,

Hello OSRM community,
For test purpose, I try to extract road network from an other source that
OSM. Anybody actually use a different source and be disposed to share the
experience ?
Furthermore, I wonder if there is more documentation about the extractor
tool as well as the lua scripting for profiles.
Thank you in advance,
Romain Wieser
