城市数字高程模型和数字正射影像建库系统架构

数字高程模型和数字正射影像是城市基础地理信息的核心载体.两者数据都是连续的地表模型数据.本论文旨在研究建立一个以这两种数据为主体的数据库集成管理系统,并能够提供基本的分析和应用功能,为城市的规划、建设、管理和社会各行业提供完善、优质和高效的地理空间数据服务.论文以宁波市两者数据的建库为例.首先介绍一些有关背景资料;然后详细研究了该系统的设计情况,包括设计的原则、技术路线,数据组织和功能规划;最后进行总结,分析了该系统架构设计的优缺点.

Research on System Structure of Building city DEM and DOM Geodatabase

DEM and IX)M are core carrier of city base GIS,the data of both are used tO describe the continuous surface of earth. The paper is aim to build a compositive geodatabase mostly composed of above-mentioned data.the system not only provide the function of base analysis and application but also provide perfect,top--quality and efficient geography spatial data service for every walk of life.The paper first instruduces background information of building the geodatabase,then traverses its planned detail,such as principle,technical route,data organized,fuction model and SO on.finally summarize its advantage and disadvantage.
