Roads API memerlukan waktu hingga 100 resource koordinat grafik, dan mengembalikan segmen jalan terdekat untuk setiap titik. Poin-poin diteruskan tidak perlu menjadi bagian dari jalur berkelanjutan.
Jika Anda menangani titik GPS secara berurutan, gunakan Paskan ke Jalan.
Permintaan
Permintaan ke jalan terdekat harus dikirim melalui HTTPS, dan mengambil tindakan berikut bentuk:
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.

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
