海域使用面积测量精度的探讨

Discussions on the Precision of Sea Using Area Survey

讨论了海域使用面积的计算方法以及海域使用面积测量的误差来源,分析了海域使用面积测量的精度,并给出了实例分析;根据实例分析,建议提高《海籍调查规范》中对离岸的界址点精度要求,建议大范围面积测量的面积计算在椭球面上计算。

The method for calculating the sea using area and the error origin of sea using area survey are discussed, the precision of sea using area survey is analyzed, and the analysis of example is given. According to the example analysis, it is suggested that the accuracy of the offshore boundary points in the ＇Specifications for Sea Area Use Register Investigating＇ should be improved, and that in a wide range of area survey the area calculation should be carried out on an ellipsoid surface.
