摘要
针对海底管道检测数据处理中涉及到的地理坐标成果和起点距成果的不统一,研究了海底管道检测数据处理中成果互算内容及其方法,并提出了基于ARCGIS Engine实现成果互算的计算机自动化处理方法。该研究成果在册镇海底管道检测中得到应用,并对于其他管道检测数据处理及断面测量数据处理提供了借鉴和参考。
In data processing from a detection for a submarine pipeline,its horizontal coordinates can hardly be converted to a certain distance from an initial point. In order to solve this problem,this article proposed a mutual conversion calculation method for the results of the horizontal coordinates and the ones of certain distances from an initial point. Also a method of automatic mutual conversion calculation based on Arc GIS Engine is proposed. The method was applied in Cezidao-Zhenhai submarine pipelines detection.
