Min. Sightings: The minimum number of sightings a track requires before it is recorded as a track. Toggle the 🛇, ≤ and ≥ buttons to define the value.
Min. Speed: The minimum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
Max. Speed: The maximum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
...
False Alarm Probability: This enables you to filter by one or more track classification types. Just click the required false alarm probability. Toggle the 🛇, ≤ and ≥ buttons to define the value.
Classification Filter: Enables you to filter by one or more track classification types. Just click the required types to highlight them or deselect all to remove the filter. Classification options are:

The results of a Track Query are displayed as a list in the Results panel:
...
History: Select this icon to open the Track Details window.
StatusVideo Playback:Change Select the status to draw specific attention to the track Play Video icon to play back the Videoloft video. This requires the Videoloft Plugin to be enabled and configured. Please refer here: /wiki/spaces/TUN/pages/2305163265.
Status: Change the status to draw specific attention to the track, and save from default track data culling.
Track Correlation: This feature searches for previous tracks that have been marked as lost, which are likely to be associated with the selected track. If the system detects such a correlated track, it will highlight it.
On the top left of the Track Query panel there are the following icons to be used with selected tracks:
...
ML Classified: If the ML Classification feature has been enabled in the Track Engine configuration, then this will be selected, then this will be selected.
False Alarm Probability Min: The system calculates a false alarm minimum probability score for each track.
False Alarm Probability (%)Max: The system calculates a false alarm maximum probability score for each track.

Add Truth Data
...
Clicking on the Add Track button will open an Add Truth Data panel.
This is used within the ML (Machine Learning) Classification feature which uses the first 10 sightings of a track in order to identify the classification of that track.
...
First Sighting: Sets the first sighting to be used for the truth data. This allows you to ignore the first part of the track if its not useful to be included as part of the truth data.

We recommend using only a few good examples for the Truth Data, and a balanced number of each classification type, as having too many of one classification type can bias the system. |
ATI
This query searches through the Automatic Track Initiation data, ATI, which concerns how tracks are acquired. The results display the start point of the tracks pathways - the point at which tracks are first detected, within the time period and record limitations. The ATI points are displayed as coloured squares. The variables are decided by the following categories:
