The AFC-900 aerial camera developed by the Beijing Institute of Space Mechanical and Electrical Engineering has a total pixel of more than 900 million. It is the world's leading ultra-large format plane array aerial camera. It has large format, high precision, high operating efficiency, etc., and meets the requirements of 1:500 large scale drawing accuracy [1]. In order to verify the application effect and accuracy of the camera, the camera has completed a large number of flight tests. This paper has organized the verification test according to the requirement of 1:500 large scale drawing accuracy. It has been verified that the AFC-900 aerial camera DLG conforms to the 1:500 digital line drawing plane accuracy and elevation accuracy, the DEM basically conforms to the first-level accuracy of the 1:500 digital elevation model accuracy index, and the DOM conforms to the 1:500 digital orthographic accuracy. It can be widely used in many fields of aerial photogrammetry, such as topographic mapping, updated GIS database, aerial surveying and mapping, topographic surveying, land resources survey, environmental monitoring, ecological environment survey, urban fine management and disaster emergency monitoring, evaluation, etc.
