黑龙江工程学院数字校园信息系统设计与实现
摘要
随着教育信息化建设的不断深入,高等院校数字校园的建设和应用已经成为新一轮信息化建设研究的重点。数字校园建设旨在将学校各类信息资源进行统一的、科学的组织与管理,从而实现信息资源的共享,并能够服务于学校教学、科研、人才培养等各种活动。
地理信息系统是数字校园建设的重要组成部分,然而,目前的地理信息系统在体系结构上较为封闭,在客户端表现力不足,并且缺乏互操作能力,不能很好地满足数字校园应用环境的要求。鉴于此情况,本文在分析比较国内外高校各种数字校园建设体系的基础上,围绕GIS在数字校园建设上的应用需求,设计了一种新型的适合于数字校园的WebGIS模型,该WebGIS模型的主要特点是,增强了系统的互操作能力。重点研究了WebGIS在数字化校园系统的应用,应用该模型架构,设计出了基于WebGIS的黑龙江工程学院数字校园系统,该系统采用MapXtreme作为GIS内核;数据库分别使用了空间数据库和属性数据库;选取GML作为对外的数据交换格式;在接口方面选用了提供GIS功能的SOAP进行调用;将GML文档转换为SVG用于客户端的地图显示;系统采用J2EE架构,具有良好的开放性和可扩展性。
目前,本系统已在黑龙江工程学院试成功运行。经实际应用表明,本系统设计合理、功能完善、使用方便,提升了数字化使用的技术和工作效率,推进了校园管理工作的数字化、现代化进程,对于加强教学管理、促进数字校园的长远发展起到了积极的作用。
As education continues to in-depth information technology, digital campus and its related technologies and applications are becoming the new round of university information technology research. Digital Campus to all kinds of information resources for the school uniform, scientific organization and management, in order to achieve the sharing of information resources and services in teaching, research, training, etc activities.
GIS is an important part of the digital campus, however, the current mainstream system of geographic information systems, structural closure, the lack of interoperability, lack of client expression, and many other defects, can not meet the requirements of the digital campus applications.In view of this situation, this paper analysis and comparison of domestic and foreign universities in various digital campus building program, based on GIS around the campus environment in the digital application requirements, design a new campus WebGIS for digital model, the model of WebGIS main features is to enhance the interoperability of the system with open architecture and client-side vector.Focus on the WebGIS in Digital Campus System, the application of the model structure, designed based on the WebGIS Heilongjiang Institute of Digital Campus System, the system uses MapXtreme as the GIS core; database were used spatial database and attribute database; to GML as External data exchange format; to provide GIS functionality SOAP call interface; using XSLT technology to GML documents into SVG map display for the client; system using J2EE architecture, openness and good scalability.
Currently, the system has been run successfully in the Heilongjiang Institute. The practical application shows that the system designs is reasonable, comprehensive, easy to use, enhancing the digital use of technology and efficiency, and promote the campus management of digital, the process of modernization, strengthening education management, promotion of digital campus long-term development has played a active role.
