摘要
通过使用陆域RTK测量和水上侧扫声纳测量综合确定填海海域使用界址线的技术方法,可以获得清晰准确、完整的实际填海区域内、外界址线。详细研究了使用侧扫声纳时的解析精度,结果表明侧扫声纳解析精度主要取决于资料后处理的技术手段,而不是设备性能本身。通过采用了精度更高的数字化处理流程,解决了拖鱼位置精度和目标物位置判定的问题,使陆域RTK测量和水上侧扫声纳测量都能获得优于0.1m的测量精度。文中详细阐述了测量数据综合解析的过程,报告编写的主要内容和重点,并给出了报告的主要目录结构。
Using the technical method of combining the data of land RTK survey and water side scan sonar survey, accurate and com- pletely boundary line is produced. The analytic precision of side scan sonar survey is detailed studied and the result shows that its analytic precision depends on the post-processing instead of equipment itself. A more accuracy digital processing flow to solve tow fish position and target determinant problems is adopted. At last land RTK and water side scan sonar data post-process accuracy are both less than 0.1m. Survey data comprehensive analytic flow, main content and keystone and the main catalog structure of the report are listed.
