Webb12 feb. 2024 · Used Shapely Line String (Ramer-Douglas-Peucker) to simplify the lines Problem Ramer-Douglas-Peucker is not able to simplify the line as desired. If increasing the RDP tolerance, results are not satisfactory. The target should be to represent the polygon as good as possible with least lines possible. WebbChoose between shapely or simplification. Shapely adopts solely Douglas-Peucker and simplification both Douglas-Peucker and Visvalingam-Whyatt. The package simplification is known to be quicker than shapely. Default is shapely. simplify_algorithm : str
