Check if two polygons intersect

This feature checks if two polygons intersect. The code sample creates two polygons and uses the booleanIntersects function to determine if they intersect.

const turf = require('@turf/turf');

const polygon1 = turf.polygon([[
  [-2, 2],
  [2, 2],
  [2, -2],
  [-2, -2],
  [-2, 2]
]]);

const polygon2 = turf.polygon([[
  [1, 1],
  [3, 1],
  [3, -1],
  [1, -1],
  [1, 1]
]]);

const intersects = turf.booleanIntersects(polygon1, polygon2);
console.log(intersects); // true

Check if a line intersects a polygon

This feature checks if a line intersects a polygon. The code sample creates a line and a polygon and uses the booleanIntersects function to determine if they intersect.

const turf = require('@turf/turf');

const line = turf.lineString([
  [-1, 0],
  [1, 0]
]);

const polygon = turf.polygon([[
  [-2, 2],
  [2, 2],
  [2, -2],
  [-2, -2],
  [-2, 2]
]]);

const intersects = turf.booleanIntersects(line, polygon);
console.log(intersects); // true

Check if a point intersects a polygon

This feature checks if a point intersects a polygon. The code sample creates a point and a polygon and uses the booleanIntersects function to determine if they intersect.

const turf = require('@turf/turf');

const point = turf.point([1, 1]);

const polygon = turf.polygon([[
  [-2, 2],
  [2, 2],
  [2, -2],
  [-2, -2],
  [-2, 2]
]]);

const intersects = turf.booleanIntersects(point, polygon);
console.log(intersects); // true
