| Abstract: | The purpose of this paper is to study, design and develop, and make experiments on the storage organization of mass images and vector data. Methods employed are theoretical analysis and contrast experiment. The results indicate that first the mass images data storage technology based on database mode, which is independent from GIS and database platform software, and second the mass vector data storage technology based on Oracle Spatial have been designed, developed and verified. It is concluded that the invented technologies have solved the technical bottleneck of the national database management system for Second National Land Survey and have meet the application requirements of the land survey data management at national level. |
