Dear Rolando, OSRM (Open Source Routing Machine) is a routing engine designed to run on OpenStreetMap data.
There is a public instance of the engine, a demo server. This server has limitations (https://github.com/Project-OSRM/osrm-backend/wiki/Demo-server) like the number of requests/minute, or in your case the maximum size of a requested distance matrix (10000, meaning 100 origines x 100 destinations). As they say :"he demo server usage is restricted to reasonable, non-commercial use-cases. We provide no guarantees wrt. uptime, latency, or data updates." A solution is to run your own instance of the server to get rid of these limitations. The prefered and simplest way to run an instance is to use a Docker container (https://github.com/Project-OSRM/osrm-backend#quick-start). When launching the Docker you'll have to set a large value for the --max-table-size parameter. Something like: docker run -t -i -p 5000:5000 -v "${PWD}:/data" osrm/osrm-backend osrm-routed --algorithm mld --max-table-size 9000000 /data/berlin-latest.osrm The osrm R package is an interface between R and OSRM. The default server used by the package is the OSRM demo server. But you can change the default server with : options(osrm.server = "http://0.0.0.0:5000/", osrm.profile = "driving") Cheers, Timothée [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
