Generate a great circle "trajectory" from [lat1,lon1] to [lat2, lon2]. ％ Resulting points will be seperated by approximately delta_ft feet. ％ By default, delta_ft = 100 feet. All lat/lon inputs & outputs are in ％ degrees. (Generate a great circle trajectory from [lat1, lon1] to [lat2, lon2]. Resulting points will be seperated by approximately delta_ft feet.
