Efficient Acquisition of Geographic Big Data: Domestic Three-Line Stereo Aerial Photography System

As one of the main approaches to acquire geographic data, aerial remote sensing is of great significance to the development of the geographic information industry in the era of big data. By taking the domestic three-line stereo aerial photography system as the main research object, this chapter analyses the information application demands for the development of aerial photography system by geographic big data acquisition, introduces the development status of aerial remote sensing equipment, describes the working principles and technical indexes of three-line stereo aerial photography system, and discusses the information application prospect of the aerial photography system in aspects such as digital urban construction, earthquake relief works, resource aerial remote control, environmental protection, and homeland security.
