Vias mais próximas

Mantenha tudo organizado com as coleções Salve e categorize o conteúdo com base nas suas preferências.

O Roads API usa até 100 coordenadas independentes e retorna o trecho de via mais próximo de cada ponto. Os pontos aprovados não precisam fazer parte de um caminho contínuo.

Se você está trabalhando com pontos de GPS sequenciais, use Alinhar às vias.

Pedidos

Uma solicitação de vias mais próximas precisa ser enviada por 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.

A resposta usa o esquema a seguir.

NearestRoadsResponse

FieldRequiredTypeDescription
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

FieldRequiredTypeDescription
requiredLatitudeLongitudeLiteral See LatitudeLongitudeLiteral for more information.
requiredstring

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 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

requirednumber

Latitude in decimal degrees
