Abstract: A specification of an expected border of a bounded area is received. One or more images of at least a portion of the bounded area that is at least a threshold distance away from the expected border are received to generate a model of the bounded area. A current location position of the aerial vehicle is used to determine that the aerial vehicle is within the threshold distance away from the expected border. In response, an updated expected border is determined using the generated model of the bounded area and a border image of at least a portion of the expected border captured by an image sensor.
