Generate random geojson

The random module provides a way of quickly constructing random, correct GeoJSON objects. You provide the skeleton of the document using type t and tweaking some of the parameters. For example:

{ let random_structure = FC (List.init 100 (fun _ -> { properties = None; geometry = Point })) }

val random : f:(unit -> float) -> r -> t

random ~f r produces random GeoJSON based on the structure provided by r and using the random float generator f. Note the random geometry maker will follow the rules of GeoJSON (for making Polygons for example).
