Abstract


In recent years, components, networking and virtualization is a new trend in the development of geographic information systems. New model of component-based software development as a geographic information system, improve system reusability and maintainability demonstrated unparalleled advantages, and therefore get the attention of all aspects, component-based geographic information system software with the of emerged. Virtual Geographic Environments generation system, for instance, describes the development component geographic information system process design, practice and reconstruction. Design, practice the reconfigurable component geographic information system aimed at the overall structure of the system layout design of object-oriented thinking, using design patterns to increase the high reusability and ease of maintenance of the system design; COM components to build various functional modules; reconstruction theory based on the completion of the improvement of the existing system code. This article combined with specific system to do some research in design patterns, components, and reconstruction of three: 1, design patterns, object-oriented design methods are an important and indispensable. The design pattern shows how to use the basic technology such as objects, inheritance, and polymorphism. The design pattern Kabuki you can describe \Component geographic information systems in the design process, we have adopted a more mature design patterns to help us improve the reusability and maintainability of the system. Software reuse is not only reflected in the extent of the source code, is also reflected in the level of binary code. COM the best way to achieve binary code reuse, while COM is also the cornerstone of the component geographic information system. This paper discusses the basic concepts of COM-start to the end of a two-dimensional display components cornerstone of the components of this component geographic information systems and fully discussed. 3, the reconstruction of the emergence of largely a good idea for us to rationalize the program logic to improve code reusability. Reconstruction of the big difference between theory and other theories, component of geographic information systems in use reconstruction theory has its own particularity, that reconstruction is an important link in the component geographic information systems design, an optimization of existing systems, and is a long-term commitment to a process of optimization. In this paper, based on the reconstruction theory, summed up in the reconstruction of the system should focus attention on matters, for reconfigurable component geographic information system applications to do the exploration.
