【摘要】 本文介绍了地理信息系统(GIS)、组件式地理信息系统(ComGIS)概念,对ComGIS的主要技术进行了分析,阐述了课题的研究背景及课题研究的主要内容,描述了供水管网系统的分析、设计、实现及实现过程中涉及的关键技术和创新点,实现了供水管网C/S和B/S两种模式的开发。本文主要以GIS技术在供水管网中的应用为研究对象,通过设计系统的架构、空间查询、空间分析等功能,介绍了GIS空间几何实体及数据结构,最终设计全组件化的GIS系统。论文阐述了系统开发的软件环境搭建,包括软件的安装及安装完毕后系统环境变量的配置。系统选用组件式地理信息系统软件——GeoMedia,通过VB语言完成本系统的C/S模式的二次开发,完成了查询、检索、统计、空间拓扑分析和应用分析等功能。重点研究了开发供水管网地理信息系统的关键技术,如图层管理机制、加载地形图、智能关阀、MapInfo文件格式到GeoMedia文件格式的数据转换,充分利用了GIS的空间分析功能。然后在GeoMedia WebMap应用软件的基础上,同样采用组件式技术在ASP.net语言环境下来实现本系统B/S模式的开发,完成地图的网络发布,在网络上可以对地图进行浏览、查询、修改。本文还对系统的主要创新点作了详细的阐述,如多层架构技术在供水管网程序设计系统中的应用、GeoMedia WebMap在ASP.NET上的封装。在文章最后详细介绍了多层架构技术及GeoMedia WebMap在ASP.NET上封装的实现过程。更多还原

【Abstract】 This article introduces the GIS (Geographic Information System) and the ComGIS (Component object module GIS) concepts; it analyzes the GIS main technologies and expatiates the knowledge background and main content of the topic. Also, it describes the procedure of the water supply pipe network system (SPNS) analysis, design and practical use, including the core technologies and innovation methods which related to the procedure, and how the technologies and methods help the research and developing of the SPNS dual mode: C/S and B/S.This article discusses the GIS technology in the water supply pipe network application; learn from designing system framing, spatial inquiry, and spatial analysis functions, so as to finalize an entire module GIS system. Thus, it carries on a more thorough elaboration on the module technology. It also introduces the GIS space geometry entity and the construction of data.The article expatiate the building of the system development’s software environment, including the installation and the setting of the system environment variable. The system selects the module type geographic information system software—GeoMedia, through the language of VB develop the system of C/S pattern, has completed the function of the inquiry, the searches, the statistical, the spatial analysis situs analysis and applied analysis and so on. Has studied the development water supply pipe network geographic information system essential technology with emphasis, such as the chart level management mechanism, the increase topographic diagram, intellectualized turn off the valve, data conversion from the MapInfo file formats to the GeoMedia file formats, have fully used the GIS spatial analysis function. And then in the base of GeoMedia WebMap application software, similarly uses the module type technology down to realize this system B/S pattern development in the ASP.net language environment, completes the map release in the network, may carry out the browsing, the inquiry, the revision in the network to the map.This article also detailed elaborates the system main innovation spot, such as Multi-framing Technology in water supply pipe network programming system application, GeoMedia WebMap on ASP.NET seal. A detailed introduction is made at the end of the article, reffering to the multilayered struct technology and GeoMedia WebMap the realization process which seals on ASP.NET.更多还原
