Re: [OSRM-talk] Feed OSRM with Postgis

Hi François, Ah. Well, the step of deduplicating and finding connected nodes will not go away - OSRM requires a *graph*, not disconnected geometry, so you won't be able to get away from the problem of turning your LineStrings into connected data. OSM's data structure (ways & nodes) has this

Hi François, Well, it *could* be done. It would all boil down to providing an alternative for `ParseOSMData` here: https://github.com/Project-OSRM/osrm-backend/blob/master/src/extractor/extractor.cpp#L211 That function is responsible for parsing the OSM file, and copying/converting the OSM

Hi Daniel, Despite it's a pretty old thread regarding feeding OSRM with postgis geometries, I have new lights to bring up 2017-11-30 18:09 GMT+01:00 Daniel Hofmann : > OSRM is a routing engine for OpenStreetMap and the OpenStreetMap extracts > usually come in xml or pbf

Re: [OSRM-talk] Feed OSRM with Postgis

OSRM is a routing engine for OpenStreetMap and the OpenStreetMap extracts usually come in xml or pbf formats. We're using https://github.com/osmcode/libosmium in the osrm-extract binary; you theoretically _could_ switch it out with calls to your database but that will be a bigger lift I guess,

Re: [OSRM-talk] Feed OSRM with Postgis

Yes, if all your data comes from a database the best way to get it into OSRM is to map your data to the OpenStreetMap tagging schema. You can either create an .osm.xml or even an .osm.pbf if you need the compression and compactness; you can use e.g. libosmium to write both formats. Good luck,

[OSRM-talk] Feed OSRM with Postgis

Hi all, I was recently asked to feed OSRM with other data than OSM files which are stored in a PgSQL db. Is this even possible ? The data we want to process doesn't come from OSM db, should we produce an osm xml file with those data prior to use osrm-extract ? I know OSRM can query a postgis DB
