DESIGN AND APPLICATION OF GIS SOFTWARE PLATFORM INTEGRATED DSS FACED E-GOVERNMENT
L. Wang, A. Qiu
Both Geographic Information System (GIS) and Decision Support System(DSS) are playing a important part in government affairs management or Electronic Government (E-Government). But GIS and DSS are usually independently working, the interactive relation of both is unsubstantial, so that application of E-Government to GIS is inconvenient and inefficient.
This paper put
forward a new idea for designing software platform based on integration GIS and
DSS according to target of E-Government construction in
The software platform is divided into three parts: application generate tools, application server and client module. The tools are deal with spatial data, such as input, processes, edit, application theme generate/modify in server side. Application server runs in server side which receives and analyzes client’s request, then, gets spatial and non-spatial data from database and send them to client. For complicated spatial operation, which could not be performed in client side, such as spatial analysis, the application server will call component in server side to perform the operation. Client side module is consisted by display and user interface.
This platform acquired succeed application in a series of project of electronic government application, search after a new way of GIS development facing electronic government affairs. For example: General National Situation Information System; Flood & Drought Prevent Information Server System; West Development Information Server System and so on.
