基于AO的校园GIS开发设计 摘要 随着高校的扩招，校园面积不断扩大，校内公共设施，如地下给、排水管线、电力线、道路、建筑、停车场、运动场等，都面临着新建、扩建及更新换代的问题。因此，准确反映校内公共设施的基础数据显得尤为重要。这些基础数据均与地理位置联系密切，且时间跨度大、覆盖面广、数据量大、数据变动频繁、管理部门多、管理方法落后。上述诸多因素给数据管理带来了一系列问题，如数据不统一、历史资料难以完整保留，数据查询、更新、统计困难，使用效率低。地理信息系统技术、空间数据库技术及GIS集成开发技术为解决上述问题提供了强有力的工具，构建数字校园已是必然趋势。[1]本文以本校园GIS的建设与开发为背景，详细介绍了校园GIS的开发过程，借助Microsoft Visual Basic 6.0通用开发平台以及ESRI公司的地图控件ArcObjects进行了GIS系统的二次开发，实现了地图的放大、缩小、平移和还原功能，建筑物信息查询以及地图的输出功能等。以供学校管理，外来参观者查询。 关键: 地理信息系统；ArcObjects；数据处理 Development and Design of Campus GIS Base on AO Abstract With the expansion of colleges and universities, expanding the campus area, Such as the Mass Transit to, drain lines, power lines, roads, buildings, car parks, sports grounds and so on, are faced with new, the issue of expansion and replacement. Therefore, it is particularly important to accurately reflect the basis data of public facilities in schools. These basic data are in close contact with the location , and large time span, and wide coverage, large amount of data, data changes frequently, management, and management methods behind. The above-mentioned factors to bring about a series of data management issues, such as the data is not uniform, the integrity of historical data is difficult to retain, data query, update, statistical difficulties, and inefficient use. Geographic information systems technology, space technology and GIS Integrated development of technical to solve the above problems provides a powerful tool, Construction of Digital Campus is an inevitable trend. In this paper, the construction of the campus and development of GIS for the background, described in detail the development of campus GIS，With Microsoft Visual Basic 6.0 development platform as well as general ESRIs ArcObjects map control to the secondary development of GIS system. The realization of the map to enlarge, reduce and restore the function of translation, building information, as well as features such as the output map. For school management, foreign visitors
