Internet GIS Approach to Multisource Data and Geoprocessing

Most of recent researchers believe that a lack of awareness, and problems of accessibility of 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). In order to solve these problems, the vector graphic seamless link with main database model and new WWW GIS system have been developed with Java and JDBC. This paper introduces Internet GIS approach to mutlisource data and geoprocessing, and the principle and functions of Internet GIS.
