Problems solved by technology

[0009] 1. The subjectivity of technical operations: relying on the personal experience of planners to operate, lack of quantitative data support, and technical difficulties
[0010] 2. One-sidedness of technical standards: Some technical methods still rely on individual spatial elements for coordinate correction, lack of operation methods for screening reference points of spatial elements, and technical standards are too one-sided
[0012] 4. Low work efficiency: the technical process of planning is cumbersome, and a lot of repetitive work is required in map interpretation, which takes a long time and is inefficient

Embodiment Construction

[0030] This example uses a historical map of Weifang City. Through the analysis of historical ancient maps, it can be known that Weifang has a long history. By the Ming and Qing Dynasties, a unique urban form of "turtle and snake two cities interdependent" was basically formed. After 1912, the city developed rapidly. By 2000 The walls and foundations of the two cities of Guishe and Snake basically disappeared. In order to restore the city's historical features, Weifang City Planning Department, through the analysis of historical documents, believes that the urban form of "turtle and snake interdependent" is one of the core values ​​of Weifang's urban history and culture, and is an important material carrier of Weifang's local cultural characteristics. Therefore, the "turtle The reappearance of the urban morphological characteristics of "snakes relying on each other" is a key point in future development planning.

Abstract

The invention relates to an urban historical map restoration method based on spatial grid hierarchical positioning and belongs to the technical field of urban planning. The method is based on a computer in combination with a spatial topology algorithm, and comprises the steps of taking coordinate reference points in the historical map and actual archaeology point coordinates as fixed reference points by use of the CAD (Computer Aided Design) software, obtaining index data and building a topology correction model, performing grid correction on the spatial coordinates of spatial features in the urban historical map which is age-old and relatively low in accuracy, and automatically an engineering drawing that can be directly used for statutory plans such as the urban plan of conservation of historic cultural cities and the plan of conversion of historical and cultural blocks by use of drawing equipment. The urban historical map restoration method is used for overcoming the shortages of subjectivity and randomness in decision making by use of the intellectual activities of the human brain for urban historical map interpretation in the urban construction engineering, and consequently, the working efficiency is greatly improved and higher accuracy can be provided.

Description

technical field [0001] The invention relates to a method for restoring urban historical maps based on spatial grid layered positioning, and belongs to the technical field of urban planning. Background technique [0002] The urban historical map is a record carrier that reflects the city's natural environment, political, economic, and cultural conditions and their evolution, and also shows the changes in geographical conditions and urban space over a long period of time. Since the historical map shows the spatial pattern in the history of the city, it has become an effective method to trace the historical development and explore the historical context, provide a reference for the future development and construction of the city, and is an important basis for the site selection and construction of urban planning projects. [0003] However, due to the limitations of surveying and mapping technology in the period of urban historical map drawing, the drawings of spatial features o...
