How to make a few days' itinerary?

It's best not to record the movement track for several days continuously, because the file is too big to use. It is best to track it once a day, or once.

If a track has been recorded for several days, it can be divided into one song every day or one song at a time. The segmentation trajectory can be segmented by software, such as GPS trajectory editor. Domestic sports assistant software, such as outdoor sports assistant, also has the function of track splitting. You can also split it directly manually. GPS tracks are all in text format, and manual splitting or merging is also convenient.
