海洋探测中HYPACK原始记录文件的数据提取和图形表达

DATA EXTRACTION AND GRAPHICAL EXPRESSION FROM HYPACK RAW FILES IN MARINE SURVEY

摘要: HYPACK综合导航定位系统是广泛应用于海洋工程水下地形地貌测量的数据采集和处理软件,它支持多种定位设备和测深设备的数据采集和处理。如何正确提取所需的数据、满足不同工程测量的特殊要求,是我们在实际使用中经常碰到的问题。分析了实测HYPACK数据,以VISUAL C++6.0为平台进行程序开发,实现了在HYPACK记录的原始文件中特定数据的处理,如航迹(点位)坐标、水深值、潮位数据等。所开发的程序实现了数据的图形可视化和由数据向DXF格式的转换,实现了数据编辑和图形效果的交互。

Abstract: Hypack is a navigation and position system for marine survey, which supports many hydrographic survey devices. It is necessary to extract useful data for marine engineering survey from the logged raw data file. The paper discusses the raw data structure of Hypack and develops a software to process the data of raw file based on VISUAL C++ 6.0. Especially, the position data and sounding data are extracted. The software also can build a visual graph for the processed data and transform the graph into DXF format.
