Site selection method for measuring and calculating city super high-rise building viewing point based on atmospheric visibility

Abstract

The invention discloses a site selection method for measuring and calculating a city super high-rise building viewing point based on atmospheric visibility, and relates to the technical field of city planning. The method comprises the steps that firstly, a data statistical table of city atmosphere overall visibility in resent years is obtained, and an average value of the field of view is determined; then by screening city flat terrain data, city super high-rise buildings are obtained; based on the average value of the field of view, the optimal selected site of the viewing point is determined by the superposition of the fields of view of the different super high-rise buildings; finally, secondary superposition is conducted on a superposition result and city rivers, mountains, roads, large building facilities, historical buildings and the like, and the selected site of the viewing point is determined. On the basis of fully-quantified survey, statistics and calculation, the rational analysis result of the field of view of the city super high-rise buildings is obtained through the data, accordingly, the basis is provided for site selection of the super high-rise building viewing point, and the target of more reasonably and efficiently making use of the precious city space is achieved.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to a site selection method for viewing points of urban super high-rise buildings. Background technique [0002] At present, the purpose of research on viewing urban landscape resources based on line of sight is mostly focused on the level of utilization control and protective control, such as the strategic viewing landscape and local viewing rights in London planning. By strengthening the penetration of landscape resources and weakening the influence of the surrounding environment The influence of resources realizes the maximization of the benefits of enjoying landscape resources in various regions of the city. Whether it is the spatial line of sight research based on plane drawing that emphasizes the analysis of internal viewpoints for the external space of buildings such as streets and rivers, or the "spindle" three-dimensional geometry research that emphasizes ...

AI Technical Summary

Problems solved by technology

In the existing studies, the analysis of viewing points of urban landmark buildings is mostly aimed at a single landmark building that has been determined, based on the analysis of elements such as sight distance, sight area, viewing angle (including vertical viewing angle and horizontal viewing angle), and space safety. , by establishing a model for the building height, the farthest viewpoint and the closest viewpoint, and finally determining the location of the viewing point, there is a lack of research on the optimal location of viewing points for multiple landmark buildings in the city based on atmospheric visibility measurements
