【Abstract】 Constructing the Environment Data Model (EDM) is a key step of the Modeling and Simulation of Synthetic Natural Environment (SNE). In this paper, the definition of EDM and methods for constructing EDM are discussed, then a method which combines the Object Oriented technology and the data field concept is adopted to construct the EDM, and finally the environment database is implemented based on this method.更多还原
