Oracle-based spatial database interface technology research

This task is to investigate relevant issues of Spatial database interface. The Technology of Spatial Database is the core technology of GIS, while Hie interface of GIS and Spatial database is to solve the interaction problem of application program and spatial database. This paper introduces the concept of spatial database, the specification of OpenGIS, the Oracle Call Interface; design a spatial database interface based on Oracle; then we introduce a design and realization of spatial database interface, which is aiming at Oracle Spatial, basing on OCI and C-language, conforming to the specification of OpenGIS . At last a display system is implemented and such contributes to the development of GIS application systems.
