基于任务过程的战场环境对象时空数据组织模型

军事信息系统始终以面向任务为核心，战场环境数据模型也是围绕作战任务来建立的。针对目前基于任务的战场环境信息系统研究尚不完善，现有的GIS时空数据模型还不能完全满足战场环境时空分析的需要。在对目前几种经典的时空数据模型分析的基础上，以基于对象的数据模型为理论基础，以过程驱动方法为建模机制，设计了适合战场环境领域的时空数据组织模型结构，实现了对复杂环境对象的可操作性。通过模型在战场环境分析系统中的应用，证明了其任务过程和地理空间数据的可对象化描述、组织、存储和查询功能。

Battlefield Environment Object Spatio-Temporal Data Organizing Model Based on Task-Process

The core of military information system adheres to be task-oriented, and the battlefield environment data model is also established surrounding the combat tasks. Aiming at the incomplete battlefield environment information system and the situation that the existing GIS spatio-temporal data models are unable to fully meet battlefield environment spatio-temporal analysis, a kind of task-oriented battlefield environment spatio-temporal data model needs to be constructed. Based on the analysis on few kinds of existing typical spatio-temporal data models, the spatio-temporal data organizing model structure which adapts to battlefield environment is designed through taking data model based on object as theoretical basis and process driven method as modeling mechanism, thus, the maneuverability on complex environment object is realized. Through the application of model in battlefield environment analysis system, it is proved that its task process and geographical spatial data can be described, organized, stored and checked as the object.
