Research And Implementation Of Digital Urban Planning Platform Based On GIS Technology

With the advent of information age, digital platform for the establishment of urban planning has been put on the agenda, a growing number of cities have established a three-dimensional simulation model. Our city must take the road of sustainable development, the formulation of urban development strategy requires not only information support and information service, but also need to support scientific decision-making based on information it is estimated that 75% of human information, 80% are related to the position and geographical space. Clearly, the city development city geographic information system and related technology support.Geographic information system (Geographic Information System, referred to as GIS)as a core technology of digital cities, as the establishment of digital urban planning platform offers vast amounts of data and spatial information, is the driving force behind the development of digital cities."Data" is the blood of GIS, GIS-based platform for the establishment of urban planning is inseparable from the geographical phenomenon known model, the complete model of geographic data, which also relates to the object-oriented approach. These are the basic theoretical knowledge of GIS. To achieve just only from the original two-dimensional topographic map with contour lines into three-dimensional model of the conversion will also need to digital CAD files, and finally achieved through several conversion. Second, several of the Urban Planning Platform to share the data also do without a unified management information system of urban planning, but also inseparable from the establishment of the GIS system, technical background, so while achieving the "total number of rules." Beside, today's transportation planning as an integral part of urban planning also needs the help of GIS technology to complete the analysis of existing traffic, establish and improve public transport query system, to forecast future traffic and so on. These three aspects can be said to measure the current with a "Digital City" to achieve the three indicators of the degree of maturity.Therefore, start from several aspects, we can achieve more comprehensive GIS-based platform for digital urban planning.Through the use of GIS technology to achieve results on the GIS project planning performance, the establishment of a functional module with a variety of urban planning and management information systems and traffic projections and so on.
