The Design And Realization Of Urban Planning Management Information System In Yiyang City Based On GIS

In recent years,with the integration of Changsha-ZhuzhouXiangtan city into the climax,Yincheng Yiyang,which enjoys the reputation of Changsha rear garden,has also entered the period of rapid development of urban planning and construction.The rapid development of urban infrastructure and the scale of urban planning and management are becoming increasingly onerous.In addition,the data types and data volume involved in planning approval and management are becoming larger and larger.And the requirements of government departments for the transparency of office information,urban planning information and planning government openness requirements are also increasingly high,the traditional urban planning and management methods will be in order to adapt to this era to make development and change.At this stage,a lot of urban planning The management department still uses the plane,the two-dimensional city plan method,cannot truly express the realistic landscape environment.In order to solve these problems,it is necessary to establish a complete set of information management service platform,and the urban planning assistant decision support system based on GIS is a very important part.It can simulate the reality of the environment,do the true three-dimensional,multi-angle,omnidirectional urban planning,but also can further realize the comparison of the planning plan,and realize the overall landscape analysis of the urban planning plan.Make the local and the whole more harmonious,thus make the planning plan more intuitive,scientific,and improve the efficiency of the planning auxiliary decision.In this paper,the following research is carried out for the system development: 1.Construction of urban planning auxiliary decision support system in Yiyang City based on GIS;2.To realize the integrated management of information in two or three dimensions;3 Layer management of data;4 Research on the storage and browsing of large data;5.Analysis of sunshine in digital cities.The realization of this system can help the city planning and design Institute of Yiyang City to provide the following convenience: functional realization of integrated urban planning functions;The data can provide true three-dimensional,multi-angle and omni-directional urban three-dimensional landscape for urban planning;The decision improves the science of planning and provides detailed and accurate analysis of data and optimization plans for urban planning,construction and management.Increased participation in the planning process provides better conditions for the public to have a better understanding of the results and to participate in the planning process.
