GIS Solution Based On Spatial Database

At present, geographical Information System (GIS) Solutions generally adopt the model of storing attribute data and spatial data seperately, in which the former is stored into DBMS and the latter is stored as files. In GIS C/S solutions, however, some problems cannot be easily achieved through such a model. The aim of this thesis is to probe the solution, namely, the latest spatial Database theory and the developing technologies based on it. This thesis focuses on exploring OracleSi Spatial, the database built up on the basis of this theory. Furthermore, research is made to show how to effectively make use of DBMS with spatial support to manage the spatial data and attribute data integrally.Due to the progress in managing GIS data, the developing method changes enormously. Thus on the flatform of Oracle Spatial plus MapX of Maplnfo, this thesis lists the steps of developing a telecomm network fibre management system. It specifies on developing the GIS project based on such a data managing model, and methods of loading background image, adding, deleting, updating the entities, managing the layers, searching entities.Through this research, the theory on spatial database of Oracle is explicitly and profoundly depicted along with the integral saving and management of spatial and attribute data, which in turn enables us to extend the data managing ability of RDBMS. Among other things, the thesis further discusses the application of spatial database to the products of Mapinfo. As a consequence, the standardization of GIS data management is achieved, which help users manage various spatial information conviently. The main functions of GIS solutions are also developed by the research of Oracle Spatial and Mapinfo GISplatform.
