Research on the Integration Techniques of Task-Oriented Geospatial Information Service for Battlefield

In order to make a military system more practicable, dynamic and scalable, task-oriented geospatial information service for battlefield (BGIS) need to be established. Information Integration is important means and essential precondition of BGIS construction, so BGIS was researched on from three aspects: service mode integration, service data integration and service process integration. A muti-mode uniform architecture was proposed, and it can support conventional operational mode and urgent operational mode; through the analysis of task-oriented geospatial data integration features for battlefield, a task-oriented data integration framework of BGIS was set up; the meaning of service composition of BGIS was expounded, then a new meta-model of service composition flow of BGIS was proposed. Finally, a prototype system was realized to validate correctness and feasibility of the theory and method initially.
