Aerial Photography Information Management System

Aerial photograph is original resource of the photogrammetry and the revision of topography maps, image quality directly affects the precision of mapping, work efficiency, economy index and the reliability of image interpretation. So it is necessary to take some techniques to insure image quality.Criterion,request,experience of the photogrammetry work and the development of the aerial photography are calculated, Some research work about the informations of the aerial photography and the management of these informations are studied in this paper.All the factors affecting aerial photography are considered,and some important questions of technical design of aerial photography are put forward. And then, according to the theory of aerial photography and practical experiences, some methods and measures are summarized. In combination with the developing direction and the trend of photogrammetry, the digital photogrammetry technology and the digital camera are introduced.and some methods of acquiring digital images and different characteristics between film images and digital images are explained. All these put up new requirement to aerial photography and image processing , and also afford certain theory basis for solving these new problems. It is also the important content of the aerial photography information management system, the fundamental method of utilizing GPS for navigation and aerial photography are discussed, by the theory , we get the formulas of GPS kinetic positioning and give a brief introduction of work method in practical production.Finally the design principle and the main functions of aerial photography information system are introduced,and the system is realized in this paper.
