added in 0.3.11

stateful function

Generates an infinite, randomized path of coordinates in a geospatially bounded box.

Inputs:

  • boundingBox: a geospatially bounded box defined by two points: the lower left point and the upper right point.
  • All other parameters mirror those in waypoints generator.

Outputs:

  • latitude: The latitude of the position.
  • longitude: The longitude of the position.
  • duration: The number of milliseconds between each point. Use this value to throttle the generator for speed-realism.
  • heading: The navigational heading/bearing, in degrees, of the object.
