Mapinfo与Supermap Objects数据转换的实现

Study on the Data Transformation between Mapinfo and SuperMap Objects

采用面向对象的方法,在VB语言环境下开发Mapinfo数据向Supermap Objects的转换程序,从Mapinfo数据库中提取空间要素和隐藏的属性数据,经转化转入Supermap Objects数据库中,解决了转换前后逐层对应问题,做到了空间要素与空间属性完全匹配,为农业空间信息决策提供数据支持。

In this paper, adopting object-oriented technique, the program design of data transformation between Mapinfo and Supermap Objects was developed under VB environment. Abstracting the spatial factor and hidden attribute datas from Mapinfo database, and shifting to the Supermap Objects database, the layer-layer corresponding before and after the data transformation was solved,and the spatial element and spatial attribute was completely matched, which provided support for decision-making of agriculture special information.
