My main goal is to combine linestrings into a polygon. Is there a way to accomplish this using a library like Turf.js, or are there any geometrical rules to follow ?

I Tried building the concave hull of all points but this couldnt produce a valid polygon.


I had to split polygons into linestrings of two kinds: line intersections and outerlines of the polygon, so that i can simplify each individual line, and then concatenate the lines to form a simplified polygon. The individual linestrings are almost the same as the initial polygons, but concatenating them again to a valid polygon seems to be the harder part.
