Abstract: The AMS-3000 wide-field three-linear-array stereoscopic aerial survey system (hereafter referred to as the AMS-3000 system) is China’s first independently developed airborne linear-array aerial survey system. It can obtain panchromatic and R-, G-, and B-band multispectral images. However, the data quality of these images lacks quantitative assessments and analyses. Focusing on the area along the Jinsha River within western Panzhihua City, Sichuan Province, this study assessed the spectral quality of the data obtained from the AMS-3000 system in terms of grayscale, texture, and energy features, and noise level. Moreover, this study compared the AMS-3000 system with the internationally recognized ADS100 aerial photography system and assessed the geometric accuracy of the AMS-3000 system using the 1∶2 000-scale terrain data. Additionally, this study analyzed the effectiveness of the AMS-3000 system in the geological industry by applying it to the investigation of the mineral resource exploitation status and geologic hazards. Overall, this study serves as a reference for the application promotion and improvement of the AMS-3000 system.
