Plan a route with OSRM

This is a wrapper around viaroute that returns a single route between A and B.

route_osrm(from, to, l = NULL, alt = FALSE, ..., singleline = TRUE)

Arguments

from	Text string or coordinates (a numeric vector of length = 2 representing latitude and longitude) representing a point on Earth.
to	Text string or coordinates (a numeric vector of length = 2 representing latitude and longitude) representing a point on Earth. This represents the destination of the trip.
l	Only needed if from and to are empty, in which case this should be a spatial object representing desire lines
alt	Boolean value to return alternative routes (default = TRUE).
...	Arguments passed to viaroute()
singleline	Should a single line be returned? Default is TRUE

Note

The public-facing OSRM routing service (the default) only provides routing for cars by default. For details, see https://github.com/Project-OSRM/osrm-backend/issues/4530.

Examples

# NOT RUN {
from <- c(-1.55, 53.80) # geo_code("leeds")
to <- c(-1.76, 53.80) # geo_code("bradford uk")
r <- route_osrm(from, to)
plot(r)
r_many <- line2route(flowlines_sf[2:9, ], route_osrm)
plot(cents)
plot(r_many, add = TRUE)
# }
