Openrouteservice Snapping — ors_snap • openrouteservice

Snap coordinates to road network

ors_snap(
  locations,
  profile = ors_profile(),
  radius,
  format = c("geojson", "json"),
  ...,
  api_key = ors_api_key(),
  output = c("parsed", "text", "sf")
)

Arguments

locations: List of longitude, latitude coordinate pairs, alternatively a two column matrix or data.frame.
profile: Route profile, defaults to "driving-car".
radius: Maximum radius in meters around given coordinates to search for graph edges
format: Response format, defaults to "geojson"
...: Optional parameters as described here
api_key: Character scalar containing openrouteservice API key
output: Output format. By default the response is being parsed to a list-based R object
