Incorrect Maquest Direction Route API Feedback


I am integrating the MapQuest API Direction Routing function into my website. However, when I submit my request to the API, it returns incorrect routing points between 2 destinations.

Below is the request form I POST to the API: http://www.mapquestapi.com/directions/v2/route?key=[APIKEY]

   {
        "locations": [
                {
                    "latLng": {
                        "lat":  37.47601247,
                        "lng": 126.96594338
                    }
                },
                {
                    "latLng": {
                        "lat": 37.4713402954355,
                        "lng": 126.95234849232048
                    }
                }
        ],
        "options": {
            "avoids": [],
            "avoidTimedConditions": false,
            "doReverseGeocode": false,
            "enhancedNarrative": true,
            "generalize": 0,
            "narrativeType": "text",
            "routeType": "fastest",
            "shapeFormat": "raw",
            "unit": "k"
        }
    }

And the results that I received, I used the startPoint.lng and startPoint.lat in the maneuvers, but that doesn't seem to be correct

Below is the return results and map illustrations:

Incorrect Routing!

Are there any parameters I have to adjust to archive the correct information? I have tried to change generalize parameter but it does not help much. I used to get the location really precise about a month ago... This is strange to me

Demostration


Solution

  • MapQuest's map/route data in South Korea is lacking a lot of detail. We hope some day to have more detailed routing in the area.
