A city space growth ring map making and analyzing method

Abstract

The invention provides a city space growth ring map making and analyzing method. The method comprises the steps of importing three-dimensional vector information data of a city into a geographic information system to form a map base map module; performing geographic information analysis of building distribution on buildings of different construction ages, performing city space growth ring history slice auto-correlation analysis on the basis of the geographic information analysis, superposing the analysis results and converting the results into contour lines, and establishing a city space growth ring three-dimensional analysis module based on the contour lines to form a city space growth ring analysis information module; establishing layers of different attributes for different objects of city space growth ring analysis information and city vector information, performing information data superposition according to geographic coordinates and displaying a city space growth ring map. The method correlates the city space growth ring analysis results and the geographic information, realizes geographic space demonstration of the city space growth ring analysis, can make thematic maps efficiently and conveniently, and can widely meet the current requirements of city planning and design engineering practices.

Description

technical field [0001] The invention relates to a method for making and analyzing maps, and more particularly to a method for making and analyzing urban space annual rings. Background technique [0002] Cities are the main spatial forms of human agglomeration. In the period of rapid urbanization, how to grasp the future development direction of cities, predict and control the urban spatial form has become an important issue facing urban development in my country. This requires in-depth exploration and analysis of the objective laws of the emergence and development of cities, the process and mechanism of urbanization from the perspective of spatial form and historical succession. The urban space annual ring is a further interpretation of the urban spatial form from a historical perspective. It is closely related to the urban spatial form and layout. The city presents the characteristics of historical fault slices and the law of spatial development and expansion in the shape o...

Problems solved by technology

[0003] At present, the main research content of urban spatial form at home and abroad is mostly the inner space of the city and the outer form of the city, relatively little use of information technology to study the evolution and development trend of urban form, most of the research based on information technology is static research, and there is a lack of dynamic time-series-based research In particular, there is no relevant analysis and research on urban spatial annual rings, and there is no urban spatial annual ring analysis map technology and invention based on geographic information systems.
