[0002] With the development of infrastructure construction and digital geological information platforms, engineering geological maps, as crucial data for engineering design and risk control, possess significant secondary utilization value. However, the current market lacks unified evaluation and trading standards for geological map data, primarily exhibiting the following problems: 1. Map value assessment lacks objective standards, relying heavily on expert experience, leading to strong subjectivity and high reuse costs; 2. A quantitative model lacking a positive correlation between complexity and value is lacking, making it impossible to quantify the relationship between engineering value and factors such as map structural complexity and data density; 3. The absence of a pricing mechanism in the trading market results in opaque value of geological maps as data assets across different application scenarios, hindering their circulation as digital assets.

[0067] The first embodiment of this invention provides a method for assessing the commercial value of engineering geological maps. Based on the fusion of multidimensional complexity indicators and market factors, it achieves commercial value assessment of engineering geological maps, which can be used to improve the standardized valuation capabilities of geological maps and realize the asset-based trading and intelligent management of map data. The following is a combination of... Figure 1 Please provide a detailed explanation.

[0068] like Figure 1 As shown, in step S100, engineering geological maps in a preset format are obtained.

[0069] The above steps specifically include:

[0070] Input data includes: geological maps in CAD / GIS format; drilling data, scale and other metadata information; and application scenario tags (such as high-speed rail, residential, highway, etc.).

[0071] like Figure 1 As shown, in step S200, the engineering geological map is evaluated based on the constructed value assessment index system. The evaluation indexes include layer complexity, structural complexity, and data accuracy. The layer complexity is used to measure the structural complexity of geological layers in the geological map. The structural complexity is used to measure the geometric complexity of the morphology and interaction of structural lines. The data accuracy is used to comprehensively measure the data information in the map, including scale, exploration point density, and data quality.

[0072] The above steps specifically include:

[0073] S210, Layer Complexity Calculation (C layer )

[0074] Layer complexity C layer The formula used to measure the structural complexity of geological layers in a geological map is as follows:

[0075]

[0076] in:

[0077] L i : The basic complexity coefficient of the i-th type of geological layer;

[0078] w i Industry weighting coefficient;

[0079] N: Number of geological layer types, including faults, karst, stratigraphic boundaries, etc.

[0080] In this embodiment, the layer parameter library is as follows:

[0081] Fault: L = 0.8, w = 1.2

[0082] Karst: L = 0.7, w = 1.5

[0083] Stratigraphic boundary: L = 0.2, w = 0.5

[0084] Example: A geological map contains one geological boundary layer, one karst layer, and one fault layer. Then:

[0085] C layer =0.01×[(0.8×1.2)+(0.7×1.5)+(0.2×0.5)]=0.0211

[0086] S220, Construction Complexity Calculation (C geo )

[0087] Construction complexity C geo The geometric complexity used to measure the shape and interaction of construction lines is calculated using the following formula:

[0088] C geo = 0.6 × FD + 0.4 × D cross

[0089] The fractal dimension FD is calculated using the following formula:

[0090]

[0091] Where N(ε) is the number of grids required to cover the construction line; ε is the grid edge length; It is the slope of the logarithmic function, estimated by the logarithm of the number of covered grids at different scales, i.e., grid sizes.

[0092] Example: The image size is 512×512 pixels, the grid sizes are 2, 4, 8, 16, and 32 respectively, and the number of grids is 42000, 18000, 8200, 3800, and 1650. The fitted result is FD = 1.63.

[0093] Construction line intersection density D cross Calculation formula:

[0094] D cross =(N cross / A)×0.1

[0095] Where: N cross Let A be the number of intersection points and A be the area of ​​the map sheet.

[0096] Example: 68 intersection points, area 3.4 km² 2 →D cross =2, then C geo =0.6×1.63+0.4×2.0=1.778.

[0097] S230, Data Precision Calculation (C)precision )

[0098] Data precision C precision The formula used to comprehensively evaluate data information in a map, including scale, exploration point density, and data quality, is as follows:

[0099] C precision = 0.3S + 0.5D + 0.2Q

[0100] The scale score S is calculated using the following formula:

[0101]

[0102] Where scale is the scale bar;

[0103] Example: scale = 2000 → S ≈ 0.017.

[0104] Exploration point density D, calculation formula:

[0105] D = tanh((N) borehole / A)×10 3 )

[0106] Where A is the map area and borehole is the number of boreholes;

[0107] Example: If there are 48 boreholes, the area is 2.0 km². 2 If so, then D≈1.0.

[0108] Data quality Q, calculated using the following formula:

[0109]

[0110] R match This indicates the degree of consistency with historical data.

[0111] Example calculation:

[0112] If S = 0.017, D = 1.0, Q = 0.874, then C precision =0.3×0.017+0.5×1.0+0.2×0.874=0.6799.

[0113] like Figure 1 As shown, in step S300, the value index of the engineering geological map is obtained by weighted fusion calculation based on the results of each evaluation index.

[0114] The above steps specifically include:

[0115] Based on the combined results of the three complexity categories, and considering the application scenario and market adjustment coefficient, the value index V of the engineering geological map is calculated using the following formula:

[0116] V=(0.4×C layer +0.3×C geo +0.3×C precision )×W×M

[0117] in:

[0118] W: Application scenario weight, such as high-speed rail 1.5, municipal 1.0, etc.;

[0119] M: Market adjustment coefficient, obtained by fitting historical transaction data, generally between 0.6 and 1.8.

[0120] Example:

[0121] If C layer =0.0748, C geo =1.778, C precision =0.6799, W=1.5 (high-speed rail), M=1.4, then V=(0.4×0.0748+0.3×1.778+0.3×0.6799)×1.5×1.4=1.098

[0122] like Figure 1 As shown, in step S400, a pricing recommendation report for the engineering geological map is generated based on the value index of the engineering geological map.

[0123] The above steps specifically include:

[0124] A pricing recommendation report is generated based on the value index V. The report includes:

[0125] 1. Value Index (Standardized score from 0 to 100)

[0126] 2. Detailed scoring of each sub-indicator (layer complexity, construction complexity, data accuracy)

[0127] 3. Scenarios and Market Regulation Factors

[0128] 4. Suggested transaction price, formula as follows:

[0129] price = 10e 0.05V

[0130] Example:

[0131] V = 1.098 → price = 10 × e (0.05×1.098) ≈105,600 yuan
