Embodiment

[0040] This embodiment provides a large-scale reconnaissance and demarcation layout method that takes into account multiple factors, such as figure 1 shown, including the following steps:

[0041] S1. Obtain the weights of the political area factor, terrain factor, traffic factor, and building factor respectively

[0042] In this embodiment, the multiple factors include: political area factors, terrain factors, traffic factors, and building factors. According to the historical data of reconnaissance and demarcation, the weights of political area factors, terrain factors, traffic factors, and building factors are obtained by using multiple linear regression methods; the sum of the weight coefficients of each factor is 1,

[0043] Namely: λ 1 +λ 2 +λ 3 +λ 4 = 1

[0044] The historical data of reconnaissance and demarcation includes the locations where boundary pillars and signboards are set up, the locations where boundary pillars and signboards are set, and the correspond...

Abstract

The invention provides a large-range exploration calibration layout method considering multiple factors, and the method comprises the steps: respectively obtaining the weights of an administrative area factor, a terrain factor, a traffic factor and a building factor according to the exploration calibration historical data through employing a multiple linear regression method; carrying out equal grid division on the boundary line according to a proportion scale to obtain a plurality of unit grids; respectively acquiring an administrative area factor coefficient, a terrain factor coefficient, a traffic factor coefficient and a building factor coefficient of each unit grid; according to the weights of the political area factors, the terrain factors, the traffic factors and the building factors and the coefficients of the political area factors, the terrain factors, the traffic factors and the building factors of all the unit grids, the multi-factor-based range exploration calibration layout credibility of all the unit grids is calculated; and retaining the unit grids of which the credibility is greater than a credibility threshold value, and establishing a large-range exploration calibration layout. The technical problem that in the prior art, the working efficiency of boundary line exploration calibration is not high can be solved.

Description

technical field [0001] The invention relates to the technical field of terrain surveying, in particular to a large-scale reconnaissance and delimitation layout method taking into account multiple factors. Background technique [0002] In recent years, in the policy of national land space planning, it is clearly pointed out that the three control lines of ecological protection red line, permanent basic farmland and urban development boundary shall be implemented with the most stringent ecological environment protection system, cultivated land protection system and land conservation system. As an insurmountable red line for adjusting economic structure, planning industrial development, and promoting urbanization, it will lay a solid foundation for the sustainable development of the Chinese nation. [0003] In order to ensure the implementation of the above policies, the delineation and demarcation of the boundary line is an important measure to ensure the accurate landing of t...
