Don Stemper explains how the U.S. military captures images from both sides of a plane. Mappers use stereo projectors and drafting tables equipped with special magnifying eyewear to outline the contours of hills, allowing troops to understand each hill's exact height from flat photographs. They then incorporate these details into the maps, transferring the information onto plastic with specific colors to identify key landmarks.
