摘要
根据沙丘地形的特点，探讨并实践RTK测量沙丘的基本方法与步骤，同时利用精度为毫米级的全站仪对RTK进行高程精度评定，其误差范围为2～7cm，证明RTK精度能够满足沙丘动态监测的要求。数据结果分析表明昌黎新开口南侧沙丘高度降低，且整体向西南移动。
According to the sand dunes terrain＇ s characteristics, this paper explores and practices the basic sand RTK surveying methods and steps, then assesses the elevation for RTK accuracy in the range of error of 2 -7cm through making use of total station about mm precision-class,proves that RTK precision can satisfy the quest of the sand dunes dynamic monitor. The results of data analysis indicated that the dune high degree on the south side of the new hatch is lowering and moving southwest.
