Ближайшие дороги

Оптимизируйте свои подборки Сохраняйте и классифицируйте контент в соответствии со своими настройками.

Roads API принимает до 100 независимых координат и возвращает ближайший сегмент дороги для каждой точки. Пройденные точки не обязательно должны быть частью непрерывного пути.

Если вы работаете с последовательными точками GPS, используйте Привязка к дорогам .

Запросы

Запрос ближайших дорог должен быть отправлен по протоколу HTTPS и имеет следующий вид:

https://roads.googleapis.com/v1/nearestRoads?parameters&key=YOUR_API_KEY

Required parameters

  • points

    The path to be snapped. The path parameter accepts a list of latitude/longitude pairs. Latitude and longitude values should be separated by commas. Coordinates should be separated by the pipe character: "|". For example: path=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796 .

    Note: The snapping algorithm works best for points that are not too far apart. If you observe odd snapping behavior, try creating paths that have points closer together. To ensure the best snap-to-road quality, you should aim to provide paths on which consecutive pairs of points are within 300m of each other. This will also help in handling any isolated, long jumps between consecutive points caused by GPS signal loss, or noise.

NearestRoadsResponse

FieldRequiredTypeDescription
optional Array< SnappedPoint >

An array of snapped points.

See SnappedPoint for more information.

SnappedPoint

FieldRequiredTypeDescription
required LatitudeLongitudeLiteral See LatitudeLongitudeLiteral for more information.
required string

A unique identifier for a place. All place IDs returned by the Roads API correspond to road segments.

optionalnumber

An integer that indicates the corresponding value in the original request. Each value in the request should map to a snapped value in the response. However, if you've set interpolate=true, then it's possible that the response will contain more coordinates than the request. Interpolated values will not have an originalIndex . These values are indexed from 0 , so a point with an originalIndex of 4 will be the snapped value of the 5th latitude/longitude passed to the path parameter.
