The Study And Application Of GIS Spatial Data

Geographic Information System (GIS) is a computer system that is used to collection, storage, management, deal, query and analysis of the geographic data. The geographic data is composed by spatial data and attribute data. 80 percent or above of the system data has its spatial property, moreover the application of the Spatial data management is very popular. With the storage of spatial data being supported by relational database, it is reality that we can use DBMS with spatial support to manage spatial data and attribute data integrally.First, this paper introduces the development of GIS, and discusses the main structure, research content, developing trend of GIS. Then based on the basic concepts and features of spatial data, we analyze the organization and storage of spatial data by using the object-oriented holistic GIS data model. Focused on the procedure of spatial data, we research the input, maintaining, analysis and publication mechanism of spatial data . We research the theory of Oracle spatial database, introduce storage of spatial data, mechanism of index and spatial analyze in Oracle.In the end, we introduce the plan choose Oracle and MicroStation GeoGraphics to explore the GIS application system.Through the realization details discussion of management and application about spatial data, we provide a useful mechanism to manage the geographic spatial data, and successfully realize the GIS of a city fire control.
