摘要：The latest Geographic Information System (GIS) technology makes it possible to administer the spatial components of daily ��business object,�� in the corporate database, and apply suitable geographic analysis efficiently in a desktop-focused application. We can use wireless internet technology for transfer process in spatial data from server to client or vice versa. However, the problem in wireless Internet is system bottlenecks that can make the process of transferring data slower. One of the reasons that system bottlenecks could happened in this situation is because spatial data is too large. Fine tuning spatial database, however, is an essential issue that must be considered. This paper focuses on a study in quadtree spatial indexing using Oracle spatial database and how to show the geographical map using MapViewer in the web application so we can use in any devices including mobile GIS application. Spatial database systems are now expected to be self-managing, self-healing, and always-up. We researchers and developers have our work cut out for us in sending all these features to optimize delivering data. The purposes of this research are to make an optimization in the speed of spatial data processing for clients with a limited communication bandwidth and to improve the response time.
