NettetThere are different simplification algorithms, which will generate slightly different results. Simplification algorithms Retain critical points (Douglas-Peucker) The Retain critical … To make things easier, we decide to simplify my polygon. Simplification means that we want to express the same geometry, using fewer points, but trying to preserve the original shape as much as we can. The easiest way is to open QGIS and use its Simplify processing tool. Se mer Douglas-Peucker, or sometimes Ramer–Douglas–Peucker algorithm, is the better known of the two. Its main aim is to identify those points, which are less important for the overall … Se mer Visvalingam-Whyatt shares the aim with Douglas-Peucker – identify points which could be removed. However, the principle is different. Tolerance, or epsilon, in this case, is an area, not a distance. Visvalingam-Whyatt, in … Se mer Let’s figure it out. I will use a long randomised line and Python package simplification, which implements both algorithms.
