স্ন্যাপ টু রোড

Roads API একটি রুট বরাবর সংগ্রহ করা 100টি জিপিএস পয়েন্ট পর্যন্ত নেয়, এবং গাড়িটি যে রাস্তা দিয়ে ভ্রমণ করছিল সেইসব পয়েন্টগুলিকে স্ন্যাপ করে একই রকম ডেটা ফেরত দেয়। ঐচ্ছিকভাবে, আপনি অনুরোধ করতে পারেন যে পয়েন্টগুলিকে ইন্টারপোলেট করা হবে, যার ফলে রাস্তার জ্যামিতিকে মসৃণভাবে অনুসরণ করে এমন একটি পথ তৈরি হবে।

অনুরোধ

রাস্তায় স্ন্যাপ করার জন্য একটি অনুরোধ HTTPS এর মাধ্যমে পাঠাতে হবে এবং নিম্নলিখিত ফর্মটি গ্রহণ করতে হবে:

https://roads.googleapis.com/v1/snapToRoads?parameters&key=YOUR_API_KEY

Required parameters

path
The path to be snapped. The path parameter accepts a list of latitude/longitude pairs. Latitude and longitude values should be separated by commas. Coordinates should be separated by the pipe character: "|". For example: path=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796 .
Note: The snapping algorithm works best for points that are not too far apart. If you observe odd snapping behavior, try creating paths that have points closer together. To ensure the best snap-to-road quality, you should aim to provide paths on which consecutive pairs of points are within 300m of each other. This will also help in handling any isolated, long jumps between consecutive points caused by GPS signal loss, or noise.

Optional parameters

interpolate
Whether to interpolate a path to include all points forming the full road-geometry. When true, additional interpolated points will also be returned, resulting in a path that smoothly follows the geometry of the road, even around corners and through tunnels. Interpolated paths will most likely contain more points than the original path. Defaults to false .

উদাহরণ

নিম্নলিখিত অনুরোধটি রাস্তার জ্যামিতিতে নির্দিষ্ট পয়েন্টগুলি স্ন্যাপ করবে৷ ডেটার এই নির্দিষ্ট সেটটি একটি বৃত্তাকার রাস্তা অনুসরণ করে; interpolate=true সেটিং নিশ্চিত করুন যে ফেরত জ্যামিতি রাস্তার বক্রতার সাথে মেলে। interpolate=false দিয়ে, স্ন্যাপ করা পথটি এখনও রাস্তা অনুসরণ করবে, কিন্তু ফলস্বরূপ পলিলাইন ততটা মসৃণ হবে না।

SnapToRoadsResponse

Field	Required	Type	Description
`snappedPoints`	optional	Array< SnappedPoint >	An array of snapped points. See SnappedPoint for more information.
`warningMessage`	optional	string	A string containing a user-visible warning.

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
