Research of dynamic base state method for spatio-temporal data model

摘要

Based on the analysis of existed base state with amendments data model, this paper proposed a dynamic base state method for spatio-temporal data model. By introducing the conception of dynamic base state and dynamic storage space, the data structure has been analyzed and retrieval process has been developed. Then, by comparison with existing models in our experiment, this method proved to be the most efficient method with the least disk space occupation.
