Jalan Terdekat

Roads API memerlukan hingga 100 koordinat independen, dan menampilkan segmen jalan terdekat untuk setiap titik. Titik yang diteruskan tidak harus menjadi bagian dari jalur yang berkelanjutan.

Jika Anda menggunakan titik GPS berurutan, gunakan Paskan ke Jalan.

Permintaan

Permintaan ke jalan terdekat harus dikirim melalui HTTPS, dan berbentuk seperti berikut:

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.

Contoh

Permintaan berikut menampilkan serangkaian segmen jalan berdasarkan daftar koordinat yang ditentukan.

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
