point-in-polygon

Determine if a point is inside of a polygon.

This module casts a semi-infinite ray from the inquiry point and counts intersections, based on this algorithm.

If you need a numerically robust solution and are willing to trade some performance for it, use robust-point-in-polygon.

example

var pointInPolygon = require('point-in-polygon');
var polygon = [ [ 1, 1 ], [ 1, 2 ], [ 2, 2 ], [ 2, 1 ] ];

console.log(pointInPolygon([ 1.5, 1.5 ], polygon)); // true
console.log(pointInPolygon([ 4.9, 1.2 ], polygon)); // false
console.log(pointInPolygon([ 1.8, 1.1 ], polygon)); // true

methods

var pointInPolygon = require('point-in-polygon')
var pointInPolygonFlat = require('point-in-polygon/flat')
var pointInPolygonNested = require('point-in-polygon/nested')

pointInPolygon(point, polygon, start=0, end=polygon.length)

Return whether point is contained in polygon.

point should be a 2-item array of coordinates
polygon should be an array of 2-item arrays of coordinates or a flat array of coordinates
start is an offset into polygon. default 0
end is an offset into polygon. default polygon.length

The flat or nested is detected automatically. Or you can use the specific methods if you want to skip the check.
