I am using LeafletJS. I want to create buffer around point. after Selecting a point buffer radius will be specifed by user in feet. After searching of awhile I found this link of JSTS. does JSTS buffer works with leafletJS ?? I am not able to find any sample for this.

Any Other solution to archive same will be appreciated.

Update 1

After look into the code of JSTS and searching for a while, I came to a conclusion, there is no conversion between JSTS geometry and Leaflet JS geometry. so it is not possible to use it without implementing conversion.

Just to add for future reference, I got JSTS to work with Leaflet.js by exporting / importing GeoJSON between the two libraries.

It's obviously not very efficient if you're doing a lot of processing but for simple one off conversions it's a pretty straightforward solution.

function buffer(leafletGeometry, distance){
    var reader = new;
    var input =;
    input = input.geometry.buffer(distance);

    var bufferGeoJSON = new;
    return L.geoJson(bufferGeoJSON);

You can do this using turf. Here is some code for an example:

var turf = require('turf') // this line is for node.js, but you do not need it in the browser
var pt = {
  type: 'Feature',
  geometry: {
    type: 'Point',
    coordinates: [0, 0]
  properties: {}
var unit = 'miles'

// 10 mile ring
var buffered = turf.buffer(pt, 10, unit)


turf's inputs and outputs are all simply GeoJSON. There are no special turf types. buffered is a regular GeoJSON object, so you can add it to your map like this:


I recommend reading both the turf documentation on data and the Leaflet documentation on GeoJSON before going much further.

How does one get the buffered turf feature to the Leaflet map? I was hoping for GeoJSON layer, but can't get it to work (no layer with buffered feature is displayed). Could you elaborate this point, please? – TLama Apr 15 at 10:30

Can't you use LeafletJS circle? Do you plan on doing some spatial queries with that buffer?

Yes, I want to later user it in spatial query. – apaleja Apr 5 '13 at 11:34
How do you perform the spatial query ? With PostGIS ? – FredB Apr 5 '13 at 12:19
