Research And Realization Of Spatial Information System Of ASEAN Based On ArcSDE And Oracle

In the development progress of GIS,with the increasing quantity of Spatial data and the emerge of manifold and multiscale data,it is important for the performance of system to organize and manage these data well.The rational method of the organization of Spatial data can not only improve the efficiency and performance of the system,but also reduce later maintenance.Therefore,the research on solutions of Spatial database and the organization and management of Spatial data is an important content in current GIS field,and also is an necessary and significant job.This paper takes the manifold and multiscale as research object.starting with basic concept of Spatial database and the Spatial data model, similarities and differences and advantages and disadvantages of Oracle Spatial and ArcSDE which are two Spatial data engines are compared and analyzed.According to the characteristics of ASEAN data, Oracle as database platform and Spatial data engine-ArcSDE are final solution.The Spatial database of ASEAN Spatial Information System is contracted through conceptual design,logical design, physical design.And the optimization and maintenance of database are discussed,mainly focuses on backup and restore of database.The builded database has been in realize.At last ,the Spatial Information System of ASEAN on the client is developed by using MapObjects component and VB and the use of design database is realized.The main function is data query and browse,making statistic chart,orientation and overlap display for social economy statistic data,etc.
