nearest {osrmr} | R Documentation |
nearest accessible position
Description
nearest() calculates the nearest position to the given coordinates which can be accessed by car. The coordinate-standard is WGS84. Attention: The OSRM API v4 is only working locally, but not with the 'OSRM' webserver.
Usage
nearest(lat, lng, api_version = 5, localhost = F, timeout = 0.001)
Arguments
lat |
A numeric (-90 < lat < 90) |
lng |
A numeric (-180 < lng < 180) |
api_version |
A numeric (either 4 or 5) |
localhost |
A logical (TRUE = localhost is used, FALSE = onlinehost is used) |
timeout |
A numeric indicating the timeout between server requests (in order to prevent queue overflows). Default is 0.001s. |
Value
A data.frame with lat and lng
