Package Exports

turf-random

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-random) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

turf-random

generate random features

`turf.random([type='point'], [count=1], options, options.bbox, [options.num_vertices=10], [options.max_radial_length=10])`

Generates random GeoJSON data, including Point|Points and Polygon|Polygons, for testing and experimentation.

Parameters

parameter	type	description
`[type='point']`	String	optional: type of features desired: 'points' or 'polygons'
`[count=1]`	Number	optional: how many geometries should be generated.
`options`	Object	options relevant to the feature desired. Can include:
`options.bbox`	Array.<number>	a bounding box inside of which geometries are placed. In the case of Point features, they are guaranteed to be within this bounds,
while Polygon features have their centroid within the bounds.
`[options.num_vertices=10]`	Number	optional: options.vertices the number of vertices added to polygon features.
`[options.max_radial_length=10]`	Number	optional: the total number of decimal degrees longitude or latitude that a polygon can extent outwards to
from its center.

Example

var points = turf.random('points', 100, {
  bbox: [-70, 40, -60, 60]
});

//=points

var polygons = turf.random('polygons', 4, {
  bbox: [-70, 40, -60, 60]
});

//=polygons

Returns FeatureCollection, generated random features
