摘要
海洋测绘中经常需要对大范围水深原始数据进行分区潮位改正,多波束地形数据成图前也需要对数据进行筛选。针对人工处理时容易产生错漏的问题,研究了基于改进的转角法进行点与多边形相对关系的判别,并通过具体算例证明该方法能满足实际工作需要,可有效提升海洋测绘内业作业效率。
Marine surveying and mapping requires calibration of original water depth data in a large scale,and data selection before drawing multi-beam topography.To address emissions and errors in manual processing,the paper studied the relative relationship between points and polygons based on an improved rotation angle method,and proved its applicability with specific examples.The method can effectively improve the efficiency of marine data processing.
