Matches given coordinates to the road network

Parameters

• loc [String] Location of the point. (optional, default 52.542648,13.393252)
• t [String] Timestamp of the preceding point. (optional, default 1424684612)
• geometry [Boolean] Return route geometry. (optional, default true)
• classify [Boolean] Return a confidence value for this matching. (optional, default false)
• gps_precision [Number] (optional) Specify gps precision as standart deviation in meters. (optional, default -1)
• matching_beta [Number] (optional) Specify beta value for matching algorithm. (optional, default -1)

Examples

var osrm = new OSRM("berlin-latest.osrm");
var options = {
    coordinates: [[52.542648,13.393252], [52.543079,13.394780], [52.542107,13.397389]],
    timestamps: [1424684612, 1424684616, 1424684620]
};
osrm.match(options, function(err, response) {
    if(err) throw err;
});

Returns Object matchings array containing an object for each partial sub-matching of the trace. Returns Array matchings.matched_points coordinates of the points snapped to the road network in [lat, lon] Returns Array matchings.indices array that gives the indices of the matched coordinates in the original trace Returns String matchings.geometry geometry of the matched trace in the road network, compressed as polyline, but with 6 decimals. You can use the npm module polyline to decompress it. Returns Number matchings.confidence value between 0 and 1, where 1 is very confident. Please note that the correctness of this value depends highly on the assumptions about the sample rate mentioned above.
