1. Modern Android applications use the Kalman filter to accurately calculate the distance traveled, or is this no longer necessary due to improvements in the google API?
  2. How do modern developers in general decide the accuracy of building GPS routes?

Updated : At the moment of my searches, I tend to think that modern developers are simply copying solutions from the five-year-old trackers MyTracks, Open GPS Tracker.

Personally, in existing applications, only one thing prevented me: the drawn route did not always coincide with the map of the city development. I think that if you combine GPS data with data on urban development, obtained, for example, through the OpenStreetMap API, the accuracy will increase by an order of magnitude.

  • But not all cities have a map exactly, if necessary you can use a method that draws a route along the road - Saidolim
