摘要
数据库是 GIS的基础 ,而空间数据库与属性数据库的挂接则是 GIS的要点。本文以渤海区域地质信息管理系统数据为例 ,阐述了基于 GIS的海洋地学管理信息系统中数据库的组织方法 ,包括空间数据库与属性数据库数据分类、分层方案 ,命名及编码规则。在此基础上 ,重点讨论了在 VisualBasic环境下运用 MAPX实现空间数据库与属性数据库的挂接方法。
By using the MAPX method, the realization of connection of the spatial database with the attribute database is solved. This paper mainly presented an organized method of spatial data, including data standard, such as classifying, layering, naming and forming spatial database, attributing database and connecting among them with the information system set in Bohai Sea. Based on the result, the connection between the spatial database and the attribute database by MAPX was emphasized in the condition of Visual Basic.
