turf-kinks

turf-kinks

Takes a polygon and detects all self-intersections.

Note: This module uses straight line intersections, so giant edges may not be computed correctly, since the curvature of the earth is not accounted for

Experimental: attempts to correct the kinks with reasonable assumptions

##Install

npm install turf-kinks

##Parameters

name	description
polygon	polygon feature or geometry

##Usage

kinks(poly)

###Example

var kinks = require('turf-kinks')

var poly = {
        "type": "Polygon",
        "coordinates": [
          [
            [
