This function is a simplified and (because it uses GeoJSON not binary polyline format)
slower R interface to OSRM routing services compared with the excellent
osrm::osrmRoute() function (which can be used via the route()) function.
Usage
route_osrm(
from,
to,
osrm.server = "https://routing.openstreetmap.de/",
osrm.profile = "foot"
)Arguments
- from
An object representing origins (if lines are provided as the first argument, from is assigned to
l)- to
An object representing destinations
- osrm.server
The base URL of the routing server. getOption("osrm.server") by default.
- osrm.profile
The routing profile to use, e.g. "car", "bike" or "foot" (when using the routing.openstreetmap.de test server). getOption("osrm.profile") by default.
- profile
Which routing profile to use? One of "foot" (default) "bike" or "car" for the default open server.
