Typical data collected includes aerial photography, lidar, remote sensing (using various visible and invisible electromagnetic spectrum bands, such as infrared, gamma, or ultraviolet), and geophysical data (such as airborne magnetic surveys and gravity). With the needs of my country's economic development and national defense construction, there is an urgent need for a large amount of map data. Therefore, aerial surveying has developed rapidly, and various surveying and mapping departments have successively established aerial surveying agencies to conduct aerial mapping services. The application of large-scale aerial mapping technology has been widely promoted in various surveying and mapping departments.
