Track Filters


Parts of tracks look wrong. In particular, where the device is moving slowly with many turns.


You're probably using the wrong filter for your tracking purposes.

Track filters are used to remove faulty noisy GPS data, and to create idle spots (fatpoints) and trips. But sometimes the filters are not suitable for the type of vehicle (e.g. for slow-moving vehicles/persons or for city driving).


Change Track Filter for a Device Type by following these steps:

In Site Admin

1. Create a new Device Type under Site Admin > Devices > Types.

2. Click in New to make a copy of the current type.

3. Select Track Filter and change the Name and Description.

4. Select which filter you will apply to this device type.

City Drive for vehicles driving around in a city with many turns.
Slow Drive for very slow-moving vehicles, like farming machines.
Airplane for fast-moving vehicles like airplanes.
Default for long-distance vehicles.

5. Select any other setting that you want to apply to your device, then finally click on Save.

In the application

6. Log in to your application.

7. Edit the user properties 

8. Select the new device type created in Site Admin

9. Save the user.

10. After changing Track Filter, draw the track again to verify.

  • When you switch device type with a new track filter, you need to reprocess tracks for that device for new distance calculation to take effect on historical data.
