A Roads API usa até 100 coordenadas independentes e retorna o segmento da via mais próxima de cada ponto. Os pontos transmitidos não precisam fazer parte de um caminho contínuo.
Se você estiver trabalhando com pontos de GPS sequenciais, use Ajustar a vias.
Solicitações
Uma solicitação para vias mais próximas precisa ser enviada usando HTTPS e tem o seguinte
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.
Exemplos
A solicitação a seguir retorna um conjunto de trechos de via com base na lista de coordenadas especificada.

A resposta usa o seguinte esquema.
NearestRoadsResponse
| Field | Required | Type | Description |
|---|
snappedPoints
| 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.
|
SnappedPoint
| Field | Required | Type | Description |
|---|
location
| required | LatitudeLongitudeLiteral |
See
LatitudeLongitudeLiteral
for more information.
|
placeId
| required | string |
A unique identifier for a place. All place IDs returned by the Roads
API correspond to road segments.
|
originalIndex
| 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 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. Nearest Roads
points may contain several points for single coordinates with
differing location or placeId.
|
LatitudeLongitudeLiteral
An object describing a specific location with Latitude and Longitude in
decimal degrees.
| Field | Required | Type | Description |
|---|
latitude
| required | number | Latitude in decimal degrees |
longitude
| required | number | Longitude in decimal degrees |
