A track is a line of the unit movement displayed on a map. It consists of points sent by the IoTplot terminal to the server.
To go to the Tracks tab, click on Tracks in the top panel or check the Tracks box in the main menu customizer. On this tab, you can view unit tracks and work with them. You can enable markers on tracks to see the places where stops, speedings, fuel fillings and thefts, etc. have been detected.
