All the above.<\/p>\n<p>Parallax is the apparent displacement of an object relative to a background due to a change in the observer&#8217;s position. In aerial photography, parallax is caused by the difference in the line of sight between the two camera stations. The parallax of a point on a photograph is therefore due to the ground elevation, flying height, and length of air base.<\/p>\n<p>Ground elevation: The higher the ground elevation, the greater the parallax.
