【摘要】：针对界址点测量误差来源中起始误差含义、大小及其影响程度缺少精确分析等问题,基于RTK规范和地籍调查规程的相关技术指标,采用理论分析与实证相结合的方法,界定了起始误差的含义,得出了符合实际情况的起始误差的大小及其影响程度。采用极坐标法测量界址点时,其起算误差应理解为测站点与定向点之间的相对中误差;起算误差是界址点测量的主要误差来源之一;实践中定向边长应尽可能选用长距离已知边,定向边长不宜小于测站最大观测距1/2。理清了界址点测量中起始误差的含义,理论与实证的起算误差大小相当,能够用于支撑相关规程制定和修改地籍图根控制测量技术指标。
[Abstract]:In view of the lack of accurate analysis of the initial error meaning, magnitude and influence degree in the source of boundary site measurement error, based on the related technical indexes of RTK specification and cadastral investigation rules, the method of combining theoretical analysis with empirical analysis is adopted.The meaning of the initial error is defined, and the magnitude of the initial error in accordance with the actual situation and its influence degree are obtained.When the polar coordinate method is used to measure the boundary point, the starting error should be understood as the relative central error between the measuring station and the orientation point, and the starting error is one of the main error sources of the boundary point measurement.In practice, the length of directional side should be chosen as long as possible, and the length of directional side should not be less than 1 / 2 / 2 of the maximum observation distance.In this paper, the meaning of initial error in boundary point measurement is clarified. The starting error between theory and practice is equivalent, and it can be used to support the establishment and modification of cadastral map root control measurement technical index.
