var random = require('geojson-random');random.point(count, bbox)
Return count points wrapped in a FeatureCollection.
An optional bbox parameter should be an array of numbers representing
a bbox in WSEN order,
and if given, the point will reside within its bounds.
random.position(bbox?)
Return a single GeoJSON Position as a 2-element array of numbers in longitude, latitude order.
An optional bbox parameter should be an array of numbers representing
a bbox in WSEN order,
and if given, the position will reside within its bounds.
random.polygon(count, num_vertices, max_radial_length, bbox)
Return count polygons wrapped in a FeatureCollection.
num_verticesis default10and is how many coordinates each Polygon will contain.max_radial_lengthis the maximum number of decimal degrees latitude or longitude that a vertex can reach out of the center of the Polygon. Default is10.bbox(Optional) Bounding box in [minX, minY, maxX, maxY] order.
random.lineString(count, num_vertices, max_length, max_rotation, bbox)
Return count line strings wrapped in a FeatureCollection.
num_verticesis default10and is how many coordinates each LineString will contain.max_lengthis the maximum number of decimal degrees that a vertex can be from its predecessor Default is0.0001.max_rotationis the maximum number of radians that a line segment can turn from the previous segment. Default isMath.PI / 8.bbox(Optional) Bounding box in [minX, minY, maxX, maxY] order. This parameter is only applied to the starting point of the line.
