A track may have many points that are not required.With this method, you may delete out the unnecessary points. The important points are automatically detected and are preserved.The strength of the smoothing can be set. A low smoothing removes less points and a strong smoothing more points.
Download the track to a file.
No reduction, all points will be used
These settings apply only to the download of the track.
To reduce trackpoints you can use it with two ways: first, purely computational, it calculates the trackpoints at a simple mathematical principle, and second, the slightly more complex smoothing like Douglas-Peucker algorithm. The two methods can be combined by ticking the checkbox "Douglas-Peucker" and by using the slider.
