This option allows you to join two tracks together. The last point of the first track will be joined to the first point of the second track. This will allow you to join together tracks that are separate but really belong to the same excursion.
To do this all you have to do is load the tracks that you want to join (two or more) and select the option join tracks. You will find this option in the tracks section of the main menu or by using the context menu of the data tree, accessing the option using the label ‘Tracks’.
