Java – spring data – mongodb finds the nearest location around the route

I have a model that contains geojson points It is easy to find the closest spring data, but how to retrieve the nearest position of a given route?

I get route information from Google:

http://maps.googleapis.com/maps/api/directions/xml?origin=48.208174 ,16.717540&sensor=false&units=metric&mode=driving

Solution

The Google mapping API returns the "step" of the route, which has the coordinates of the edge of the segment

Open the street map database to provide route coordinate information. You can use it to supplement your data Get exact geo coordinates along an entire route, Google maps or OpenStreetMap
