摘　　要：本文应用GPS与数字水准仪相结合测定航外检校场像片控制点，对GPS控制网的精度和水准高程拟合精度分别进行了分析探讨。经内业解析空三加密验证，证明该方法不仅能够满足1：500比例尺地形图内业加密及成图的需要，而且较传统联测方法可提高工作效率5倍以上。In this paper, the coordinates of image control points for aerial photogrammetric calibration field are measured with static GPS and digital leveling equipment. The precision of GPS control network and the elevation fitting precision of digital leveling equipment are analyzed and studied. It is verified by encrypted aerial triangulation that this method can satisfy the requirements of the office encrypted work of 1 ： 500 scale topographic mapping and increase work efficiency by at least five times compared with the traditional surveying method.
