Manipulation of Spatial Graphical Data in RDBMS and Its Implementation in Application of GIS
Ren Liu · 2000
It is currently one of the research focuses in the fields of database and GIS for Spatial graphical data to storage in RDBMS. A data model of spatial graphical data storage in RDBMS is presented in this paper. The paper analyses the data organization and operation, the expression of spatial graphical features and system structure in the data model. According to the given data structure model, we realize the operation of storage, topologic arithmetic and topologic analysis for spatial graphical data in RDBMS based on SQL Server. Finally, an application example in land registration system is given by using the data model to implement compact spatial database engine based on SQL Server 7.0.
