将地理点与 map 上的道路匹配

Question

I tried to create an app which track the current user position and I want to display it on a map.

The problem is, when I drive by car I get 2 geopoints and if there was a curve between, then it only draws a straight line. But I would like to draw the line on the road because of logical thinking, a car only drive on a road. How can I realize that?

Here is my backgroundGeolocationConfig where I tried to set the to the lowest but it also does not work, the result is in the screenshot below.

const config: BackgroundGeolocationConfig = {
        desiredAccuracy: 5,
        stationaryRadius: 5,
        distanceFilter: 5,
        activitiesInterval: 1000,
        activityType: 'AutomotiveNavigation'
      };
    ```

I strongly recommend Google Direction API. It is free until a certain point, but it will fit your needs. Check out more here
