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
