Geographical Information Applications over the Net

چکیده
The catalytic boost of critical mass usage of the World Wide Web (WWW) has brought about the shift in the traditional geographic information systems (GIS) paradigm and engendered new challenges and opportunities. The traditional GIS paradigm involves the use of huge databases and large expensive GIS software packages confined to local disks. The new paradigm, however, enables geospatial data to be shared and accessible in the world’s information system, the Internet. Current states of the art for Web GIS applications are client-side applications and server-side applications. Server-side applications create GIS pages based on a user’s query and request through a data form, while the client-side web GIS allows GIS analysis and data processing to be executed on the web browsers of the user’s local machine. In client-side applications, GIS data and analysis tools are sent as modules to the client upon the user’s request.
