Research On Domain-driven Cop Visualization Middleware

Recently, people pay more attention to the enviroment monitoring situation. With the increasing importance of enviroment situation, continuously accumulated monitoring data, different departments build different environment visualization system. But reuse can't be done due to the lack of contact between departments, which will cause repetitive development. Investigation and study of enviroment are done to extract the common component of enviroment visualization system in order to provide solutions of enviroment visualization system.Formalization is used to describe the essence elements of visualization system in order to eliminate ambituity of natural language. The author research on different domains, such as ocean, earthquake and meteorologic, and define the enviroment visualization data storage format, the states and trasction between states using predicate logic. At the same time, ontology for enviroment situation is constructed, which is used to formalize the observation data and delimite ambiguous expression.In the architecture design, this paper adopts a layered architecture model. Various service modules are developed and packaged into different layers, which can not only reduce coupling between modules but also improve the reuse degree of each module.Finally, with the background of Guangxi meteorological visualization project, we implemented a prototype of enviroment situation platform and validate the theory.
