Application of geographic information system(GIS)in urban planning and design
In this paper,the GIS technology is used to obtain the relevant data of the case urban planning area,the digital elevation model,the slope and aspect model based on GIS software,and the 3D simulation technology of the present situation,based on the analysis of hydrological conditions and the evaluation function of construction land suitability,the topographic model map of the planning area,the 3D image map of the superposition of remote sensing data,the digital slope map of the base,the filling depth sketch map of the topographic transformation area,the topographic transformation structure map,the simulation map of the surface water catchment line of the planning area and the suitability evaluation map of the urban construction land are constructed,this paper analyzes the natural environment condition of the planning area,calculates the fill quantity and depth in the topographic transformation,verifies the feasibility of the water system planning of the planning area,and evaluates the applicability of the construction land of the planning area,it provides a reliable reference for the scientific formulation of the planning and design scheme of the city.
