Roads API menggunakan 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 yang berurutan, gunakan Snap to Roads.
Permintaan
Permintaan ke jalan terdekat harus dikirim melalui HTTPS, dan berbentuk 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.

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
