Management and optimization of geographic information based on Oracle Spatial

Hui Wang

Abstract

When geographic information is managed by MapX component,spatial data and attribute data are separated and the efficiency of data query is not high.Based on the technology of Oracle spatial,the integration storage and management are implemented.At the same time,by use of space operators to the proximity analysis,the efficiency of spatial data query is improved,and an effective solution is proposed for preventing information lost in the process of spatial data conversion.Finally,the program is applied to the EAM(enterprise asset management) system of the aviation oil company and obtained good performance.
