【摘要】 基础地理信息是信息时代地球空间信息的基础和其他各种信息的空间载体与框架。基础地理信息不仅是国民经济可持续发展科学化决策的依据和政府信息化、网络化的重要信息源,也是经济社会发展过程中各行业必不可少的重要基础信息。河北省省委、省政府高度重视我省基础地理信息产业的发展。当前,全国大部分省级基础地理信息数据库建设还处于起步阶段,省级基础地理信息数据库是省级空间数据的基础。随着信息产业的迅猛发展,建立省级基础地理信息数据库,已经成为衡量一个省信息化程度的重要指标之一。作为国家基础地理信息系统的重要组成部分,省级基础地理信息数据库在满足政府信息化工程建设和社会经济持续发展中发挥着越来越重要的作用。随着空间信息技术的发展,基础地理信息数据量及其需求日益增大,要结合新技术的发展,尽快建设好覆盖全省的多尺度、多类型的基础地理信息数据库,实现多元、多级、海量数据的高效存储和集成化管理,建立空间数据库的定期更新、共享技术体系,使基础地理数据的分发和发布服务更好地满足社会需求。本文首先介绍了河北省基础地理信息数据库系统建立的背景和目的;说明了建立空间数据库所用的关键技术,其中详细介绍了Geodatabase空间数据模型和空间数据库引擎ArcSDE技术;结合“河北省基础地理信息数据库系统”的建设,给出了空间数据库系统的数据库设计和功能实现。更多还原

【Abstract】 Fundamental geographic information is the basic of earth spatial information in the information age. It is also the space carrier and frame of other various information. Fundamental geographic information is not only the basis of national economy sustained development and scientific basis for decision-making. It is also the important information source of government information and network. Also in the process of economic and social development, it is the important and indispensable information of various vocation. Hebei provincial committee and provincial government attach great importance to development of my province basic geographic information industry. At present, the most provincial basic geographic information database building still at the starting stage.Provincial basic geographic information database is the basis of the provincial spatial data. With the rapid development of the information industry, the establishment of provincial basic geographic information database, has become a measure of the information degree as an important indicator. The provincial basic geographic information database is playing an increasingly important role to meet the information projects and socio-economic sustainable development.With the development of space information technology, the basic geographic information data and the growing demand, we need to combine the development of new technologies, as soon as to build the coverage of province multi-scale, multi-data sources, a variety of basic geographic information database. To realize the highly efficient storage and integrated management of pluralistic, multi-level, mass data. We hope the distribution and publishing services of the basic geographic data to better meet the needs of society.In this paper, first, I introduced the background and purpose of the Hebei basic geographic information database system.Next I explained the key technologies of the establishment of the spatial database, Which gave detailed descriptions of the spatial data model Geodatabase and spatial databases engine ArcSDE. Finally, Conjunction with the construction of "Hebei basic geographic information database system," I showed the design of the spatial database system and the realization of the database function.更多还原
