Calculate voronoi-style polygons based on grid with OSRM routing duration

Calculate voronoi-style polygons based on grid with OSRM routing duration

Usage

iso_osrm(
  x,
  points,
  measure = "duration",
  osrm.server = getOption("osrm.server"),
  osrm.profile = getOption("osrm.profile")
)

Arguments

x

An sf object of a grid

points

An sf object of points

measure

passed on to osrm::osrmTable, can be either "duration" (minutes) or "distance" (meters)

osrm.server

the base URL of the routing server (end with "/"!)

osrm.profile

the routing profile to use

Value

An sf object of a grid, where column 'index_min' gives the index of the input point, for which the measure is minimal

Note

The function requires OSRM to be running, with the server being

defined by the setting for the osrm package,

i.e., getOption("osrm.server") and getOption("osrm.profile")

Examples

points = points_oldenburg
x = sf::st_as_sf(iso_grid(net_oldenburg_raw, resolution = 10))
grid = isonoi::iso_osrm(x, points, measure = "duration",
osrm.server = "http://router.project-osrm.org/", osrm.profile = "car")
plot(grid)
