南方CASS到MAPGIS数据转换的实现及应用

Realization and Application of Data Transformation from CASS to MAPGIS

通过对CASS和MAPGIS两个系统明码交换文件的结构进行研究,结合两个系统的功能,通过编程实现CASS到MAPGIS的数据转换,并对图形实体数据进行重分类、分层及可视化,在不同的应用系统中实现数据共享,从而最大限度地降低GIS应用系统的建设成本,提高GIS系统建设的效率。

Through the structure research of plain code exchange file of CASS and MAPGIS, combined with the two systems＇ function, data transformation is realized from CASS to MAPGIS through programming. Figure enffty data are reclassified, stratified and visualized. In different application systems, data sharing is realized, as a consequence, the construetion cost of GIS application system is greatly reduced, the construction efficiency of GIS application system is enhanced.
