Quality Assurance process on turn restrictions using SQL
There are multiple automotive embedded systems one of which is the car navigation system. OpenStreetMap (OSM)-based GPS navigation apps are increasingly used as OSM is the only crowd-sourced and open-sourced global map. OSM is constantly improved by the worldwide OSM users, and by the map-analysts at Telenav. Therefore, the OSM permanently catches up with the changes from reality. Even though there are several map features that can be used when mapping, there are some tags specific to routing. By way of illustration, turn-restrictions, oneway roads, road name, signposts or road geometry are examples of map features that can influence routing.
