Aerial photos
Analog and digital aerial photographs
Aerial photographs are landscape images taken with analog or digital cameras from airplanes. Some of the aerial photographs from older aerial surveys are available in analog form. The aerial photographs from the special aerial survey for the photogrammetric evaluation of the 1964 and 1967 boundaries (so-called "aerial photographs") have been digitized and can be evaluated photogrammetrically at any time.
Orthophotos
Images that have had their distortions removed and therefore have a uniform scale over their entire extent are referred to as orthoimages or orthophotos. They can be overlaid with map elements, for example.
