Abstract: Battlefield geographic environment data organization is the important link of battlefield environment information guarantee service, while the well-defined data organizational process model will be beneficial for the smooth implementation of battlefield environment guarantee under joint warfare system. The existing battlefield geographic environment data organizational model lays more emphasis on the description of data status, but lacks of the process model linked with combat task, which is hard to express the causal relationship between data organization and tasks. Owing to the static model of battlefield geographic environment data object by object-oriented method and structural expression, the data organizational process model is established based on object oriented petri net, which generally describing the interaction between data and activities and data storage. Through the application of model in battlefield environment analysis platform, it is approved that the checking of data status, task events and their mutual relationship can be realized effectively.
