Abstract
Ab stract—The dynamic management of the sea area use spatiotemporal data is going to be highlighted. Through the analysis of the characteristics of the sea area use data, based on the research of TGIS and the advantages of existing spatio-temporal database model, this paper puts forward a design proposal of the sea area use spatio-temporal database .Focusing on the data organization and data storage management mechanism, the spatio-temporal database is divided into present database, historical database and alternative database. To fulfill the expression requirements for spatial, temporal, attribute information about sea area use data, the multi-table connected patterns is adapted to store the spatiotemporal data. The database also combined the sea lot connection index table to increase the query efficiency of sea area use spatiotemporal data. According to the design proposal of this paper, the storage space and redundancy has been reduced effectively in sea area use spatio-temporal database.
