Based On The J2ee The Webgis Development Platform Of Research And Application

Geographical Information System (GIS) is a software system, which can represent the spatial data and the property data of the earth in a digital way. Traditional GIS software can neither completely fit the needs of applications, nor keep pace with the mainstream of software technologies. WebGIS is a Network-Oriented GIS and new generation of GIS. It can provide a lot of internet applications with the capability of GIS functions via Web, including the retrieve, analyze and show of spatial data, etc.J2EE (Java2 Platform Enterprise Edition) is that SUN company introduced a Java-based technology. It is suitable for server applications and the Java 2 Platform Enterprise Edition. It has been increasingly widespread accepted and used in WebGIS system. The system which is based on J2EE has popular market value and a wide range of practical prospects.UGC (Universal GIS Classes) is constructed a complete set of standard C + +. And it unrelated to the core operating system with the specific library. On the UGC basis for branches, each branch different development platforms. However, they were unified kernel-based GIS Classes Universal Construction. It has the same object model and data format, and it is an important part of a total phase-GIS. GIS framework of a total phase-in of the new generation of development platforms. ComGIS have two levels and the expansion modules. For example, it faced with different development platforms So that it can be put to different components of GIS development platform. When adding new functional modules, it can be able to create new functional components.In this paper, before analyzing and comparing the common used models of WebGIS, WebGIS model is selected to construct a UGC toolkit based on J2EE, namely SuperMap IS Java .It incorporates a lot of successful design and implemental experience of popular GIS.In short, SuperMap IS Java is a WebGIS based on UGC, implemented with java. In order to implement the interoperatabilty.Finally, the design strategy of an intelligent descion-making system based on the SuperMap IS Java for the need of pinggu government was proposed.
