For the requested latitude and longitude point sequence, we provide the following:

• A sequence of corrected latitude and longitude points on the road network
• Attribute information of matched roads

The following uses are anticipated:

• Real-time tracking of the vehicle's precise location
• By analyzing vehicle travel logs, we can identify the roads the vehicle traveled on and identify dangerous driving behavior by comparing it with road attribute information

Please note the following when using this API.

• The range of latitude and longitude that can be matched is limited to within Japan.
• If the latitude and longitude points you input are far from actual roads or are spaced too far apart, matching may fail or you may be mistakenly matched to other nearby roads.
• 緯度経度1点のみをマッチングしたい場合は、shapeに同一緯度経度を2つ指定してください。
• If the distance of the matching roads between input points exceeds 2,000 meters, matching will not be performed for that section.
  If the above conditions are met at all input points, a request error with status_code=400 will occur.
• This API has a rate limit of 10 requests per second. When using this API continuously, please wait until the response to the previous request has been returned before submitting the next request.
• For this API, page views (PV) are counted as 1 for each API call.
  
  
• If the input coordinates are in a U-turn (backward) position due to GPS sway or other factors, the matching results may be as shown in the example below.
