GIS-Assisted Urban Planning System based on Urban Edge Data Modeling

In recent years, the speed of urban development is faster and faster. With the acceleration of urbanization, the nature of land use and planning layout of urban planning area have changed dramatically. This leads to a rapid increase in the amount of urban construction information, and the efficiency of information processing and transmission. Urban planning approval is the core content of urban planning management, which directly affects urban construction and land development mode. The contents of road network analysis, demolition analysis and sunshine analysis in the urban planning system can not be fully displayed in the traditional two-dimensional GIS, so the system can not provi de a reliable basis for planning decision-makers. This paper presents a three-dimensional spatial analysis system for urban planning, which inherits the characteristics of three-dimensional GIS. At the same time, the system can analyze 3D data effectively. The system makes a full study of the more important aspects of urban planning, such as space measurement, demolition management, sunshine analysis, road network planning analysis, etc., and can analyze and audit the planning results.
