Web1 Answer Sorted by: 5 if your linestring are not crossing each other on the mid points you can simply use intersects method from shapely for line in lines: for point in points: if line.intersects (point): # you have a match if the do intersect you can get first the mid points from the linestrings using shapely's method interpolate WebWhen two line segments meet at a sharp angle, a miter join will extend the original geometry. To prevent unreasonable geometry, the mitre limit allows controlling the maximum length of the join corner. Corners with a ratio which exceed the limit will be beveled. single_sidebool, optional
