State of the Art in Photogrammetric Digital Aerial Cameras

The use of digital imaging cameras for aerial photogrammetry mapping has recently been introduced in the world and has become a practical aspect. In recent years, the maps from aerial photographs using digital systems have expanded dramatically, so that a large volume of GIS maps are prepared by them. This study is a brief explanation about the digital aerial cameras and a difference between them and analog cameras is introduced. Available technologies in imaging systems such as frame size, data acquisition methods and number of imaging sensors, are also being studied. Then, the variety of digital cameras used in aerial photogrammetry based on their quality and design parameters, are compared with each other.
