The Gray Line Information Network Publishing System Design Studies

While "the digital Earth" and "the digital city" construction upsurge starting, geographic information system technology more and more widespread application to urban planning domain. At present, it already has established the urban planning management system at many major and medium cities in our country, but the mostly only was aims at in the planning management daily to manage activity carries on the simple problem analysis, the appraisal using the geographic information system. Creates this kind of present situation the reason to have very many, including technical factor and non- technical factor and so on. But the Internet/Intranet technology rapid development, the geographic information system is facing the network direction to develop. Based on the Web information gathering, the memory, the transmission, sharing and the issue technology have provided the new realization mentality and the technical method for the urban planning management system. WebGIS is expands and a consummation geographic information system item using the Web technology brand-new, the revolutionary new technology. This article depends on to WebGIS the gray line information and its background geography information issue on Internet, from Internet random a pitch point, the user may from the network digital map the real-time browsing issue gray line information, carries on the spatial inquiry and the conventional spatial analysis, dynamic "map" issue, provided a public to the urban planning supervisory work to participate in, the widespread surveillance function。This research use current advanced WebGIS technology, the GIS software visible expression ability, uses ESRI Corporation WebGIS the platform ArclMS establishment the ash line information issue system. Its key point is the WebGIS system development theory, the method and the urban planning management specialized knowledge unifies, in view of the profession demand, gives dual attention to the GIS discipline development the tendency, makes every effort to solve the solid problem.The present paper take the ash line information network issue system design and the development as a core, by the introduction, the information system develops the platform to select, the ash line information network issued the system design, the example of system design, the conclusion and the forecast and so on five parts compose, mainly has studied the domestic and foreign cities geographic information system work present situation, in particular ash line...
