MAPSTORE与ARC／INFO数据转换的方法研究

Research on Data Conversion Method from MAPSTORE to ARC/INFO

GIS空间数据具有多源性的特征，为数据综合利用和数据共享带来不便，解决多格式数据源集成一直是近年来GIS应用系统开发中需要解决的重要问题。ARC／INFO软件是当前众多地理信息系统软件中功能最强、市场占有率最高的软件。E00格式作为一种空间数据转换的事实上的标准，对于自主版权的GIS软件MapStore来说，实现两者的数据转换具有重要意义。本文分析了MapStore与ARC／INFO空间数据模型的组织特征，在比较分析的基础上设计了转换方案，并就实现过程中的关键技术进行了论述。

GIS Spatial data is multi source, and it is obstructive to data sharing and synthetic using. It is important to resolve data integration of different formats in the process of GIS software engineering. ARC/IN FO is the most powerful software among all current software, and its appropriation rate of market is the high est. E00 is a kind of universal format, so it is more significant for GIS software to realize the data conversion between MapStore and E00. In this paper, the data models of ARC/INFO and MapStore are studied, and the method for conversion is designed, and the key technologies are disscussed in the process of realization.
