基于HYPACK的矢量航迹线生成方法研究

Study of track line generation methods in vector format based on HYPACK

为了将HYPACK导航软件记录的导航数据用于地理制图,探讨了基于HYPACK原始导航数据的矢量航迹线几种生成方法,并给出了每种方法的具体思路。对这几种方法进行比较发现:按照Global Mapper中矢量文件的文本格式生成矢量航迹线文件最为简单,效率较高;直接编码生成法比较直观、容易理解,但实现效率较低,实现过程较为复杂。在.Net环境下编制了统一框架下生成几种格式的文本文件的小工具,经过验证取得了较好的效果。

To use raw navigation data from HYPACK software records in geographic mapping tools, in this paper, we discuss and propose several track line generation methods in vector format based on HYPACK. We compare these methods and conclude that the vector-format track line generation method based on the text format is the simplest for creating vector features in Global Mapper with high efficiency. While direct coding is intuitive and easy to understand, it is also the most complicated method with the lowest efficiency. We developed a simple tool for generating text files from several formats in a uniform frame in the.Net coding environment, and verified the good results achieved.
