训练模拟系统中的战场地理环境数据标准研究

Battlefield Geo-environment Data Standard in Training Simulation System

训练模拟系统对战场环境数据的要求,在分析战场环境特点的基础上,提出制订战场地理环境数据标准应遵循准确性、逻辑性、稳定性和可扩展性原则,并以此为基础设计了战场地理环境数据标准的三层体系结构,包括基础层、交互层和应用层。根据该体系结构,具体阐述了地理空间数据的分类编码标准、质量控制标准、元数据标准、转换与交互标准及地理空间数据库设计标准的作用、内容、依据,分析了各标准间互相依存与制约的关系。

According to the battlefield environment data request of training simulation system, this paper presented that battlefield geo-environment data standard should be drawing on the principles of veracity, logicality, stability and extensibility by analyzing of battlefield environment＇ s character, and frames the tri-level architecture of battlefield geo-environment data standard, includes basic level, interactive level and applied level. Based on the architecture, the classify and coding standard, the quality control standard, the metadata standard and the transformation ＆ interaction standard of geo-spatial data and the designing standard of geo-spatial database were expatiated, and their relation was analyzed.
