Abstract:Catalogue service is an important function of battlefield environment support system oriented service architecture, and it aims to introduce the multi-source massive battlefield environment information into task oriented datasets for operators. To standardize catalogue service for battlefield environment information and realize intelligent search function, the OGC-CSW specification and ontology were introduced. The framework of the catalogue service for battlefield environment information was established, and the key techniques, such as metadata information model, task ontology model and semantic search mechanism, were researched. At last, the methods were validated by the experiment.
