I have a circular hiking trail. It was digitized in a way that I cannot reproduce. It is apparently a circular path, but it consists of many individual parts that overlap completely or partially. Also, all parts have different directions. In total, I have 1000 such paths, and I want to modify them as automatically and reliably as possible so that only one line geometry remains. I have attached a sample file. If you style the line with transparency, you can see the overlaps.
