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.

No reduction, all points will be used

There are two ways to reduce trackpoints: the first, purely computational, calculates the trackpoints using a simple mathematical principle, and the second uses the slightly more complex Douglas-Peucker smoothing algorithm. The two methods can be combined by ticking the checkbox "Douglas-Peucker" and by using the slider.
Create a track by uploading a file containing trackpoints.
