摘要
为了加快少数民族地区区域经济发展,提升基础测绘对经济建设的服务能力,财政部、国家测绘局将临夏市基础测绘列入国家财政支持少数民族地区发展的基础测绘项目。在临夏市城区坐标系统改造工作的基础上,对临夏市进行1∶500数字化基础测绘生产。文中介绍了RTK技术在临夏测区数字成图中的应用情况,通过比较说明:RTK的测量精度完全能够满足1∶500地形测图图根控制的精度要求,误差分布均匀,不存在误差积累问题,并可以提高工作效率。
In order to develop the economy of national minority area, and promote service ability of foundation mapping to the economic development, the Ministry of Finance and State Bureau of Survey give Linxia city, national minority area, national finance support to process the foundation survey and mapping. According to the application of GPS RTK in Linxia city digital topographic mapping, some conclusions are given: the measuring accuracy of RTK definitely satisfies the precision of 1:500 terrain mapping control survey; the error distribution is even; it did not have the accumulated error; and the work efficiency is raised.
