Package Exports

@turf/buffer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@turf/buffer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

buffer

Calculates a buffer for input features for a given radius. Units supported are miles, kilometers, and degrees.

Parameters

feature (FeatureCollection | Feature<any>) input to be buffered
radius number distance to draw the buffer
units [string] any of the options supported by turf units (optional, default kilometers)
steps [number] number of steps (optional, default 64)

Examples

var point = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [-90.548630, 14.616599]
  }
};
var unit = 'miles';

var buffered = turf.buffer(point, 500, unit);

//addToMap
var addToMap = [point, buffered]

Returns (FeatureCollection | Feature<(Polygon | MultiPolygon)>) buffered features
