WebAug 28, 2013 · A geofence is simply an array of lat/long points that form a polygon. Once you have a list of lat/long points, you can use a point-inside-polygon check to see if a location is within the polygon.

WebMay 19, 2024 · Most geofencing algorithms in use today are reactive [15, 16], i.e. a safety remediation maneuver is triggered when the vehicle crosses a geofence boundary. This means that a geofence cannot be set at the true boundary of a keep-in area since a certain amount of space must be allocated to allow for the remediation maneuver. WebIn order to improve the safety of UAS flight, an autonomous flight UAS geofence algorithm is proposed.
