Roads API는 최대 100개의 독립된 좌표를 제공하고 각 지점에 대해 가장 가까운 도로 구간을 반환합니다. 요점 연속 경로의 일부일 필요는 없습니다.
순차적 GPS 지점을 사용하여 작업하는 경우 도로에 스냅하기를 사용합니다.
요청
가장 가까운 도로에 대한 요청은 HTTPS를 통해 전송해야 하며 양식:
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

| 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
