Hi @admin , just saw this thread and I have a suggestion. I recently wrote an algorithm to simplify GPS tracks which worked really nicely. I'm not sure if it's original but worked for me. Basically use Shoelace formula (https://en.wikipedia.org/wiki/Shoelace_formula) on a sequence of waypoints. If the area of the polygon formed by those waypoints is less than a threshold, add another waypoint to the sequence; if it's more than a threshold, turn it into a track segment and start over again with the next 3 waypoints. That way the area threshold is a single number that users can tweak for their desired level of detail, you don't have to explain a bunch of parameters. Points all in a line have low area, but the momemnt there's a turn the area increases a lot. Happy to share my Python code.
