Design on Situation Display System Based on COM Technology

With a good understanding of the functions and features of situation display applications, a novel display method is proposed under a hierarchical software architecture, which utilizes both GIS and COM technologies. To depict the method clearly, in this paper, first, the function, composition and structure of the system implemented by using the suggested method are presented. Then a feasible system design scheme is described. Also, the technical features of GIS and COM object models are analyzed. The experiences on applying software object-oriented design and interfaces design skills and map plotting strategies are introduced. Experimental results show that the suggested method is universal, extensible and efficient.
