Roads API accetta fino a 100 coordinate indipendenti e restituisce il segmento di strada più vicino per ciascun punto. I punti superati non devono necessariamente far parte di un percorso continuo.
Se utilizzi punti GPS sequenziali, utilizza Adatta alla strada.
Richieste
Una richiesta alle strade più vicine deve essere inviata tramite HTTPS e ha il seguente formato:
https://roads.googleapis.com/v1/nearestRoads?parameters&key=YOUR_API_KEY
Required parameters
points
The points to be snapped. The points parameter accepts a list of latitude/longitude pairs. Separate latitude and longitude values with commas. Separate coordinates with the pipe character: "|". For example:
points=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796.
Esempi
La seguente richiesta restituisce un insieme di tratti stradali in base all'elenco di coordinate specificato.

NearestRoadsResponse
| Field | Required | Type | Description |
|---|---|---|---|
| optional | Array<SnappedPoint> | An array of snapped points. Sometimes containing several snapped points for the same point with differing placeId or location. See SnappedPoint for more information. |

| Field | Required | Type | Description |
|---|---|---|---|
| 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. |
| optional | number |
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 or if you're
using nearest roads, then it's possible that the response will
contain more coordinates than the request. Interpolated values will
not have an |
LatitudeLongitudeLiteral
An object describing a specific location with Latitude and Longitude in decimal degrees.
