i use convex hull to get the external points of each polygon. the problem is to union the polygons. if i use the convex hull in all points i will not get a right route. The image1 of the attach is what i will get if i do the convex hull with all points. The image2 is what i am doing in the code. I need to union/merge the polygons.
