Based On Of Opengis The Digital City Public Service Platform

The proposal originated from the concept of Digital City in 1998, the U.S. Vice President Al Gore in the United States, California Science Center titled "The Digital Earth: Understanding our planet in the twenty-first century," the speech, the core idea is to use information technology as much as possible processing the Earth, the digital city is the Digital Earth in the process of a stage, whose main goal is to use digital technology to build cities, urban development, and ultimately the city's sustainable development efforts. Digital City Public Service Platform is based on the needs of the community, for the public users to open a network of geographic information services. It is an open form to show the city overview, urban planning and construction, infrastructure construction, as well as land management, population management and other urban elements, while providing users the shortest path query, hot spots, information inquiry and a series of practical features.In this paper, high-tech zones in Panzhihua City of geographic information services to the public platform, and other digital city construction platform, based on figures in city construction overseas for the relevant information, was designed and implemented a GIS-based digital urban public service platform. Platform for the construction of the GeoServer based on OpenGIS components, strict compliance with OGC specifications, in the regular map operation based on the introduction of statistics and summary, topology analysis, timing analysis, thematic maps production, enterprise information management, and maps closely related to the usefulness of functions, these functions of government decision-making, urban planning and economic development has played an important role in supporting, this article highlights the function of this part of the design and implementation. System to interface to the popular WebService technology called Ajax front-end use of mainstream technology to achieve results without refreshing. The function to meet current requirements; performance thanks to the caching mechanism, allowing the system to handle a large number of requests in a short time and the data is returned.System made use of Java language development, with strong cross-platform nature of the common in a variety of server operating systems can run well. At the same time, due to the timely processing of user requests and generate a large number of images (map data) sent to the user, therefore this system must have a clear performance advantage, in achieving the functions at the same time should pay more attention to improve performance; in bandwidth should be there is adequate protection, this point in the current network environment to meet, but to give the user a better sense of the data transmission system must take the necessary optimization and processing.Digital City is a city on City Informatization in the process of real space and digital space increasingly integrated product, which will help improve government efficiency, and administrative transparency, improve the business operating environment and expand the market space, while at work, life, travel, etc. aspects to better serve the public.GIS is a digital city a strong scientific and technological means, but based on the OpenGIS Digital City Digital City will accelerate the pace and promoting the construction of digital cities towards standardization and internationalization.
