turf-overlaps v1.0.3

turf-overlaps

find whether spatial features overlap

overlap(poly1, poly2)

Takes two Linestring, Polygon or MultiPolygon features and finds whether they overlap.

Parameters

Example

var poly1 = turf.polygon([[
  [0, 0],
  [0, 2],
  [2, 2],
  [2, 0],
  [0, 0]
]]);

var poly2 = turf.polygon([[
  [1, 1],
  [1, 3],
  [3, 3],
  [3, 1],
  [1, 1]
]]);

var overlapping = overlaps(poly1, poly2);

// true

Installation

$ npm install --save turf-overlaps

Usage

overlaps = require('turf-overlaps');

var is_overlapping = overlap(poly1, poly2);

Tests

$ npm test

Todo

• Add tests for MultiPolygon
• Add tests for testing overlaps for non-homogenous types (LineString vs Polygon, etc)
