摘　　要：本文简要介绍了徕卡ADS80数字航空摄影测量系统及特点,利用该系统进行了金坛市1200km2航摄,并完成了112km2 1∶1000航测成图。精度检测表明,基于ADS80的数字航空摄影测量系统通过采用高精度的似大地水准面模型成果,有效提高空三加密精度,从而提高大比例尺的成图精度,特别是高程精度能优于规范要求。This paper introduced the Leica ADS80 digital aerial photography system and its characteristics. By using this system, the Jintan 1200 square kilometers aerial photography and 112 square kilometers 1 ： 1000 aerial mapping was finished. The precision testing showed that the digital aerial photogrammetrie system based on ADS80, by using the high-precision quasi- geiod model result, effectively improved the three-dimentional triangulation accuracy. Thereby, improved the accuracy of the large-scale mapping, especially the elevation accuracy is better than the regulatory requirements.
