A Study on TGIS Based on Dynamic Multilevel Base State with Amendments
基于动态多级基态的修正模型的TGIS研究

It is inefficient that realizing the query and redivivus of the history information based on the modal of base state with amendments though the modal can store change data with low redundancy. Based on the character of spatio-temporal cohesion and the spatio-property's, this paper introduces a method for designing and building spatio-temporal database based on dynamic multilevel base state with amendments, through analyzing the parcel land change character of the object-oriented TGIS. The modal of based on dynamic multilevel base state with amendments (DMBSA) is derived from the modal of base state with amendments and conquer the shortcoming of the modal. At last, a self-developed software package of land cadastral information system (ReGIS) based on above model and methods is presented. The application - ReGIS states that the modal of based on dynamic multilevel base state with amendments (DMBSA)can store and manage spatio-temporal data with low redundancy and trace history information efficiently.
