Some activity tracking apps or devices automatically pause the recording when there is no movement for a while. Other trackers do not record new points when one goes in a straight line. And some users manually pause the activity, forget to resume and resume after having moved for a while.
Depending on the usage patterns one wants to segment the tracks into segments or really keep them as one long track. In order to cater for different use cases, this can be changed with a setting.
In the following you can enter a threshold. If these many seconds elapse between two subsequent points in the track, these will be considered different segments and not be connected with a straight line. Entering "0" disabled segmentation.
