Modeling spatial database incremental updating based on base state with amendments

摘要：

The incremental updating of geo-spatial databases is becoming more and more popular because the method of replacing the entire database with a new version is burdensome for the large mount of data involved. There is needed a model for geo-spatial database incremental updating in an efficient manner and a practical mode. A number of key problems of modeling the spatial database incremental updating are discussed in this paper. Firstly the base state with amendments model is introduced to manage the incremental information and historical database. Then detailed technologies such as the incremental information storage structure, creating the new version database, and spatio-temporal search are also expatiated. Finally, a prototype system for spatial database incremental updating is developed and implemented with 1:2000 topographic databases. Experimental results show that using the models presented in this paper can store incremental information effectively, and integrate the incremental information into the old databases quickly.
