There are different types of tracks depending on what technology is used to determine the locations and tracking mode set in the device configuration.
- Continuous tracks. These are the most common tracks, which are very typical for vehicle tracking applications. These tracks are represented as polynomic lines with Start and End.
- Interval tracks. For autonomous GPS trackers it is often set so the location is updated in relatively long time intervals, i.e. once per hour, once per day, etc. These tracks will be showed as numbered (1, 2… N) landmarks. For better understanding they will be connected with transparent grey lines, which, however, have little in common with the real path.
- LBS locations. If the location is defined not with satellite navigation systems (GPS, GLONASS, Galileo and others), but with some alternative LBS technologies, such as GSM or Wi-Fi signals, it’s often not very precise. To make it clear to the observer, such locations are visualised with a circle, where the radius refers to the accuracy.
- Clustered landmarks. When some vehicles stays in same place too long, you can get too many separate interval or LBSmessages for the same locations. To make it more convenient to the observer, the server will “stick” them together and show just one clustered landmark on the map. Start/end time and duration will be added to the note to this landmark
