Analysis of the Application of WebGIS ArcIMS New Technology

This paper describes the system Architecture of ArcIMS,and its operational mechanism, particularly analyzes the role of Arc XML in this system Architecture It then discusses how to run Arc IMS and how to communicate between the client and server as well as the functions of ArcXML in this Architecture emphatically Meanwhile the logical and physical layers of Server are introduced and the core of ArcIMS is discussed The functions of every layer are described in detail The basic functions of Client are also introduced from the point of view of uses,and the feature service and the image service are analysed emphatically Then ArcIMS Manager is introduced and how to manage the ArcIMS Server is also introduced,and the three functional models are described separately Finally,the securities of Website are analysed combining the characteristics of ArcIMS itself Through data security and sevice security and system security the security of Website is discussed in detail,and the methods of how to resolve the security of Website are provided
