Research And Realization Of 3D Spatial Analysis Method For Urban Planning

In recent years,China’s urbanization process is developing rapidly,and there is an urgent need for scientific urban planning.The 2D urban planning system does not adequately express the relationship between spatial objects,it can not realistic show space scene,and has been unable to meet the requirements of modern urban planning.So the demand for research and implementation of 3D spatial analysis methods for urban planning has become very urgent.For the problems that existing in the traditional 2D planning system,3D spatial methods such as basic space measurement,slope analysis,demolition information management,sunshine analysis and road network planning are studied and realized in the 3D scene.Aiming at the problems of the coordinate accuracy is low and the slope analysis is not intuitive,the method of coordinate query based on intersection judgment and the method of analysis of regional slope based on single point slope measurement are proposed.For urban demolition management chaos and did not achieve the process of the problem.This paper improved the process of demolition information management based on spatial inquiry.In order to solve the problem of road planning from the actual,inadequate detection and other issues.The paper integrated a complete set of road planning analysis process.Based on the methods,this paper designs and realizes the application platform of 3D spatial analysis method for urban planning.It uses B/S architecture,using javascript,php and other languages,it realizes spaces of space measurement,demolition management,sunshine analysis,road network analysis Analysis functions and login authentication,backstage management,roaming browsing and other auxiliary functions.The platform has improved the scientificity and efficiency of urban planning and management,and has been applied in the field of urban planning and has achieved good results.
