{name: 'line 1', distance: 145}) | ||
console.log(polygon1) | ||
console.log(polygon2) | ||
``` | ||
###featurecollection | ||

var pt2 = t.point(-75.833, 39.284, {name: 'Location B'}) | ||
var pt3 = t.point(-75.534, 39.123, {name: 'Location C'}) | ||
var fc = t.featurecollection([pt1, pt2, pt3]) | ||
console.log(fc) | ||
``` | ||
###extent | ||
Calculates the extent of all features and returns a bounding box. | ||
```javascript | ||
var t = require('turf') | ||
t.load('path/to/file/example.geojson', function(err, features){ | ||
if(err) throw err | ||
t.extent(features, function(extent){ | ||
console.log(extent) // [minX, minY, maxX, maxY] | ||

```javascript | ||
var t = require('turf') | ||
var bbox = [0,0,5,10]] | ||
t.square(bbox, function(err, square){ | ||
if(err) throw err | ||
console.log(square) // [-2.5, 0, 7.5, 10] | ||
}) | ||
``` | ||
###size | ||
Takes a bbox and returns a new bbox with a size expanded or contracted by a factor of X. | ||
```javascript | ||
var bbox = [0, 0, 10, 10] | ||
t.size(bbox, 2, function(err, doubled){ | ||
if(err) throw err | ||
console.log(doubled) // [-10, -10, 20, 20] | ||
}) | ||
``` | ||
###center | ||
Calculates the absolute center point of all features. | ||
```javascript | ||
var t = require('turf') | ||
t.load('path/to/file/example.geojson', function(layer, err){ | ||
if(err) throw err | ||
t.center(layer, function(center){ | ||
console.log(center) | ||
}) | ||
}) | ||
``` | ||
###bboxPolygon | ||
Takes a bbox and returns the equivalent polygon feature. | ||
```javascript | ||
var t = require('turf') | ||
var bbox = [0,0,10,10] | ||
t.bboxPolygon(bbox, function(err, poly){ | ||
if(err) throw err | ||
console.log(poly) | ||
}) | ||
``` | ||
###envelope | ||
Takes a Feature or FeatureCollection and returns a rectangular polygon feature that encompasses all vertices. | ||
```javascript | ||
var t = require('turf') | ||
var pt1 = t.point(-75.343, 39.984, {name: 'Location A'}) | ||
var pt2 = t.point(-75.833, 39.284, {name: 'Location B'}) | ||
var pt3 = t.point(-75.534, 39.123, {name: 'Location C'}) | ||
var fc = t.featurecollection([pt1, pt2, pt3]) | ||
t.envelope(fc, function(err, envelopePoly){ | ||
if(err) throw err | ||
console.log(envelopePoly) | ||
}) | ||
``` | ||
###centroid | ||
Calculates the centroid of a polygon Feature or FeatureCollection using the geometric mean of all vertices. This lessons the effect of small islands and artifacts when calculating the centroid of a set of polygons. | ||
```javascript | ||
var t = require('turf') | ||
var poly = t.polygon([[[0,0], [0,10], [10,10] , [10,0]]]) | ||
t.centroid(poly, function(err, centroid){ | ||
if(err) throw err | ||
console.log(centroid) // a point at 5, 5 | ||
}) | ||
``` | ||
###flip | ||
Takes a point, linestring, polygon, or featurecollection, and flips all of its coordinates from [x, y] to [y, x]. | ||
```javascript | ||
var t = require('turf') | ||
var poly = t.polygon([[[1,0], [1,0], [1,2]], [[.2,.2], [.3,.3],[.1,.2]]]) | ||
t.flip(poly, function(err, flipped){ | ||
if(err) throw err | ||
console.log(flipped) | ||
}) | ||
``` | ||
###explode | ||
Takes a Feature or FeatureCollection and return all vertices as a collection of points. | ||
```javascript | ||
var t = require('turf') | ||
var poly = t.polygon([[[0,0], [0,10], [10,10] , [10,0]]]) | ||
t.explode(poly, function(err, vertices){ | ||
if(err) throw err | ||
console.log(vertices) | ||
}) | ||
``` | ||
###combine | ||
Combines feature collection of point, linestring, or polygon features into multipoint, multilinestring, or multipolygon features. | ||
```javascript | ||
var t = require('turf') | ||
var pt1 = t.point(50, 1) | ||
var pt2 = t.point(100, 101) | ||
var fc = t.featurecollection([pt1, pt2]) | ||
t.combine(fc, function(err, combined){ | ||
if(err) throw err | ||
console.log(combined) | ||
}) | ||
``` | ||
###isClockwise | ||
Takes a ring and return true or false whether or not the ring is clockwise or counter-clockwise. | ||
```javascript | ||
var t = require('turf') | ||
var clockwiseRing = [[0,0],[1,1],[1,0],[0,0]] | ||
var counterClockwiseRing = [[0,0],[1,0],[1,1],[0,0]] | ||
var clockwise = t.isClockwise(clockwiseRing) | ||
var counterClockwise = t.isClockwise(counterClockwiseRing) | ||
console.log(clockwise) // true | ||
console.log(counterClockwise) // false | ||
``` | ||
###remove | ||
Removes any features from a feature collection that match a property value. | ||
```javascript | ||
var t = require('turf') | ||
var trees = t.featurecollection([t.point(1,2, {species: 'oak'}), | ||
t.point(2,1, {species: 'dogwood'}), | ||
t.point(3,1, {species: 'maple'})]) | ||
t.remove(points, 'species', 'dogwood', function(err, result) { | ||
if(err) throw err | ||
console.log(result) | ||
}) | ||
``` | ||
###filter | ||
Keeps any features from a feature collection that match a property value. | ||
```javascript | ||
var t = require('turf') | ||
var trees = t.featurecollection([ | ||
t.point(1,2, {species: 'oak'}), | ||
t.point(2,1, {species: 'birch'}), | ||
t.point(3,1, {species: 'oak'}), | ||
t.point(2,2, {species: 'redwood'}), | ||
t.point(2,3, {species: 'maple'}), | ||
t.point(4,2, {species: 'oak'}) | ||
]) | ||
t.filter(trees, 'species', 'oak', function(err, oaks){ | ||
if(err) throw err | ||
console.log(oaks) | ||
}) | ||
``` | ||
###inside | ||
Checks to see if a point is inside of a polygon. The polygon can be convex or concave. | ||

###contour [deprecated: split into isolines for line contours and isobands for polygon filled contours] | ||
Takes a FeatureCollection of points with z values and an array of value breaks and generates contour polygons. This is a great way to visualize interpolated density on a map. It is often used for elevation maps, weather maps, and isocrones. The main advantage over a heat map is that contours allow you to see definitive value boundaries, and the polygons can be used to aggregate data. For example, you could get the 5000 ft elevation contour of a mountain and the 10000 ft elevation contour, then aggregate the number of trees in each to see how elevation affects tree survival. | ||
```javascript | ||
var t = require('turf') | ||

###donuts | ||
Takes a set of overlapping polygons and returns non overlapping donuts. | ||
```javascript | ||
var t = require('turf') | ||
t.load('../path/to/donutsIn.geojson', function(err, donutsIn){ | ||
if(err) throw err | ||

``` | ||
###convex | ||
Takes a set of points and returns a convex hull polygon. | ||
```javascript | ||
var t = require('turf') | ||
t.load('../test/testIn/convexIn.geojson', function(err, points){ | ||
t.convex(points, function(err, hull){ | ||
if(err) throw err | ||
fs.writeFileSync('./testOut/convex.geojson', JSON.stringify(hull)) | ||
console.log(hull) | ||
}) | ||
}) | ||
``` | ||
###concave | ||
Takes a set of points and returns a concave hull polygon. | ||
```javascript | ||
var t = require('turf') | ||
var maxEdge = 2.5 | ||
t.load('../test/testIn/concaveIn.geojson', function(err, points){ | ||
t.concave(points, maxEdge, function(err, hull){ | ||
