I would say, that for each case it should be identified why the lines are there and it should be fixed acordingly.
- Multiple trips uploaded as one: Split the sequence.
- GPS started with a couple of images in the wrong place: Move or delete them.
- GPS jumped quickly off path and found it again: Move or dele the images.
Just splitting will for the latter 2 cases give images in completely wrong locations. In GIS the main problem is always data quality, and we should try to make it as good as possible.
Hmm. I just looked at Mapillary by random. It looks like a sequence where a single point jumped a lot, but even though the point is connected to others, the forward and backward arrows are disabled. Like it is part of a sequence…but isn’t? Is this a Mapillary error?
