turf-convex

turf.convex(input)

Takes a set of Point|points and returns a convex hull polygon.

Internally this uses the convex-hull module that implements a monotone chain hull.

Parameters

parameter	type	description
input	FeatureCollection.<Point>	input points

Example

var points = {
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.195312, 43.755225]
      }
    }, {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.404052, 43.8424511]
      }
    }, {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.579833, 43.659924]
      }
    }, {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.360107, 43.516688]
      }
    }, {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.14038, 43.588348]
      }
    }, {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Point",
        "coordinates": [10.195312, 43.755225]
      }
    }
  ]
};

var hull = turf.convex(points);

var resultFeatures = points.features.concat(hull);
var result = {
  "type": "FeatureCollection",
  "features": resultFeatures
};

//=result

Returns Feature.<Polygon>, a convex hull

Installation

Requires nodejs.

$ npm install turf-convex

Tests

$ npm test

deprecated turf modules: do not use or reference, for redirects only
