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.
