The Design of City Planning Decision Support Platform Based on Two - Three Dimensional Linkage Technology

Abstract

In the work of city planning, the planning and design personnel should take city roads, city transportations, drainage system and all kinds of infrastructures into account, which are closely linked with spatial position. In the area of the application of urban planning, with its powerful function in representation and analysis, GIS have remarkable advantages compared with normal information management systems. These powerful GIS function can solve the problem such as calculate and estimate of plot ratio and greening rate, the adaptability evaluation of ground and environment. In addition, GIS bring convince for urban planning work with its powerful function in scene simulation, three-dimensional display and analysis. Construction a programmed decision-making system based on GIS with the function of urban planning information management, model construction and decision-making can provide scientific decision and reference for urban planning personnel.
