RTK在沙滩修复中高程高精度地形测量的应用研究

Study on RTK Technique for High Accuracy Elevation Value in Beach Restoration and Nourishment Survey of Terrine

RTK以其无须多站架设、速度快、精度高等优点深受测量者喜欢,本文以北海银滩沙滩整治修复为例,应用RTK选取4个控制点进行配准与测区内建立的水准点进行对比。在4个控制点进行配准校正的情况下,可以应用快速模式对地形点进行精确的测量,高程精度可以达到毫米级。

RTK is welcome to measure because it has high location accuracy , and faster, fewer station to work. The paper base on wiping of beach in Beihai, undertakes the test for GPS RTK by adopting 1,2,3,4 the control point to comparison benchmark ,the result comparison proves by the test that 4 control point can survey high accuracy of millimeters in survey of terrine.
