Data reduction

To reduce the number of data points without losing the features of a data set you can apply one of several line simplification algorithm:

  • Douglas-Peucker

  • Visvalingam-Whyatt

  • Reumann-Witkam

  • Perpendicular distance simplification

  • n-th point simplification

  • Radial distance simplification

  • Interpolation (nearest neighbor)

  • Opheim

  • Lang

The desired tolerance is automatically calculated from the data but can also be changed in the dock widget.
