يستخدم Roads API ما يصل إلى 100 إحداثيات مستقلة، ويعرض أقرب جزء من الطريق لكل نقطة. وليس من الضروري أن تكون النقاط التي تم تمريرها جزءًا من مسار مستمر.
إذا كنت تتعامل مع نقاط GPS التسلسلية، استخدِم محاذاة إلى الطرق.
الكائن Requests
يجب إرسال الطلب إلى أقرب الطرق من خلال HTTPS، ويأخذ الشكل التالي:
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
