How to understand the output of OSRM match?

Question

OpenStreetMap

I have a set of raw data from GPS trackers, but if you directly display them on a map, there is often a marriage in the form of cut corners and bends.
I want to tie the track to the roads. Found an OSRM product ( https://github.com/Project-OSRM/osrm-backend) with a match map function. But something I do not understand what to do with his output.

Well, now how to get a beautiful GeoJSON?

Answer 1

Is your request malformed? it was necessary to
And read the Documentation
more carefully: The overview parameter is responsible for displaying the track geometry in the result, and you have it false
