摘要
首先介绍了万维网地理信息系统、Ｊａｖａ和ＪＤＢＣ，讨论了目前万维网地理信息系统的设计和实现方法以及存在的问题，提出了矢量图形与主数据库无缝连接模型，并使用Ｊａｖａ和ＪＤＢＣ设计实现了万维网地理信息系统软件，使客户在客户端实现放大、缩小、漫游、查询、统计和分析等地理空间分析功能。
Most of recent researchers believe that a lack of awareness and problems of accessibility to spatial data are significant bottlenecks to increasing numbers of users and applications.It is not easy for users to get spatial attribute from image of WWW Geographic Information System(WWW GIS).The image which users have received from server side,has no spatial attribute features and can not be operated easily.In order to solve this problem,the vector graphic seamless link with main database model for WWW GIS with Java and JDBC has been developed.With this model,users may be easy to operate WWW GIS,including pan,zoom,query and analysis.In client side,users operate the GIS like that in server side,and seamless link with main database.
