Modeling of Synthetic Terrain Environment and Implementation of Database
Weihua Liu · 2006
In this article,the requirements for terrain of modern military simulation systems are analyzed,and then the terrain environment data model is designed by object-oriented method.A synthetic terrain environment database based on Directed Acyclic Graph(DAG) is designed according to the terrain environment data model. Terrain data for different type of simulations are integrated.The problems of consistency,association and multi-resolution of terrain data in different type of simulations are solved.To improve the reusability of terrain data,the database is mapped to SEDRIS.The data resource is introduced and the production process of terrain environment database is analyzed.Finally,a kind of implementation method on environmental database in the form of OpenFlight is put forward,which can save the cost for developing the database.
