摘要
分析了大型无缝影像数据库的数据管理需求和系统设计原则 ,提出了多比例尺、多数据源、分布式异构的海量影像数据管理模型 。
At present, the construction of National Spatial Data Infrastructure (NSDI) and Digital Earth imminently needs efficient management of multi-scale and multi-resource mass image data. This paper gives systematic and deep researches on distributed heterogeneous management mode of super-image\|project and image-project based on commercial database management system (such as ORACLE, SQL Server) and Component Object Modal (COM) after the characteristics of image data and its management requirement is comprehensively analyzed. The design and implementation method for large-scale seamless image database management system is also described.
