摘要
GPS控制测量的边长投影变形会对测量后续工序的质量和工程建筑物的施工放样造成不利影响,探讨了GPS控制测量消除或减小边长投影变形的数据处理方法,并结合工程实例进行了验证。
Side length projection distortion based on GPS control survey affects the quality of succedent survey procedures and construction layout.The author probed into the data processing method of eliminating or minimizing side length projection distortion,and proved the method taking real project as example.
