ShapeFile与军用交换格式数据转换的研究与实现

通过对ShapeFile数据格式与军用标准格式的分析比较,指出了它们之间在对描述地理实体的分类分级、编码体系、属性结构等方面存在的差异。在对数据构成进行分析的基础上,提出了采用编写转换软件的方案来解决ShapeFile数据向军用交换格式数据的转换,重点解决了转换过程中的数据构成转换、数学基础转换、属性信息转换和注记要素提取的问题。

The Research and Implementation of the Transfer Between ShapeFile Data and Military Exchange Format Data

This paper analyses the ShapeFile data format and the military standard data format,and then points at the differences including the classification,coding hierarchy,attribute structure between them. Based on the analysis of data structure it proposes the method to solve the conversion of ShapeFile data and military standard format data by writing conversion software,this method can resolve the problems concerning the conversion of data structure,the conversion of data base ,the conversion of attribute information and the annotation element extraction in the exchange process.
