Abstract

Abstract

The main purpose of this study is to solve the problem of data sharing and consistent maintenance in distributed geological spatial database.Based upon the spatial data model of MAPGIS7.0 and the characteristics of data distribution, this paper designs a distributed multi-level server network architecture called "grid horizontal and multi-levels vertical".Under the architecture, a data exchange strategy is presented which regards geological feature class as elementary unit and it is service-oriented.The application of the strategy to nation's geological spatial database system demonstrates that: the spatial, topological and semantic consistence can be maintained effectively by means of exchanging data with geological feature class, and service-oriented operation can deal with data exchange between different operating systems and databases.In conclusion this strategy is suitable for the integrated management of a distributed heterogeneous geological spatial database.
