摘　　要：近几年来,GPS-RTK技术在数字化地形图测绘中已得到广泛应用。结合杭州富阳市1∶500数字化地形图测绘工程实例,探讨了在数字化地形图测绘中运用网络RTK进行一级控制网布设的方法、原理和可行性,并对测绘结果进行了精度分析。通过实验验证:用网络RTK施测的一级控制点方法的精度完全符合《浙江省GPS-RTK测量技术规定》的要求,此成果完全可以满足测区的1∶500数字化地形图测图需要。In recent years GPS-RTK technology has been widely used in the digital topographic surveying and mapping. In this paper,take the 1：500 digital topographic map surveying and mapping engineering of Fuyang City, Hangzhou of Zhejiang Province as example, discussed the method,principle and feasibility of conducting Grade A Control Network Layout in the digital topographic surveying and mapping by using network RTK,and conducted the accuracy analysis towards the surveying and mapping result. Verified through the practice： the accuracy of method of using the network RTK to test Grade A Control Point is full compliance with the requirements of ＂Provision on GPS-RTK Measuring Techniques of Zhejiang Province＂ ,this result can fully satisfy the needs of mapping 1：500 digital topographic map.
