【摘要】 数字正射影像具有地图的几何特征和影像特征,直观易读、信息量丰富、获取快捷,已经得到社会各界的高度认可,成为应用越来越广泛的基础地理数据资源。本文从海量数字正射影像数据管理与分发服务的角度出发,通过对空间数据库技术的发展趋势探讨,结合ArcSDE空间数据引擎的体系结构和数据模型,针对国家基础数字正射影像的数据源特点和建库要求,提出了基于ArcSDE的国家基础数字正射影像数据库建设思路和解决方案,开展了基于ArcSDE的国家基础数字正射影像数据库的存储模式研究和集成建库实践,实现了国家级海量数字正射影像数据的有效组织、安全存储、统一管理和分发服务。更多还原

【Abstract】 DOM(Digital Orthographic Map) is provided with the geometric and image characteristics of map, with straight-sight and readability, plenty of information, fast acquirement, which is widely recognized by all circles of society. Therefore, it becomes the basic geographic data that is used more and more popularly. This paper, from the view of management and distribution service of massive DOM database, discusses the development trend of spatial database technology combining with the scheme and data model of ArcSDE, aims at the characteristics of data sources of national DOM and demands of database establishment, puts forward the design sketch and resolution project of national DOM database based on ArcSDE, presents the storage patterns and integration methods of national DOM database based on ArcSDE, realizes the efficient organization, safe storage, unified management and distribution service of massive national DOM database.更多还原
