Bridge, wharf, road, ford, pipeline, cable, water intake, drainage, and other construction projects that are built across, through, or adjacent to a river or lake within the management scope of a river or lake should comply with flood control standards, shoreline planning, navigation requirements, and other technical requirements, and should not endanger the safety of dikes, affect the stability of river regimes, or hinder flood drainage.

Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein.

[0025] Figure 1 Fig. 1 shows a flowchart of an optional river-related construction project approval compliance evaluation method according to an embodiment of the present application; as shown, the river-related construction project approval compliance evaluation method according to an embodiment of the present application includes: Figure 1 S102, obtaining the license space range data of the river-related construction project, the license space range data including the construction project type data and the space range data of the river-related construction project; S104, obtaining the plot of the construction site; the plot is the remote sensing image interpretation plot data of the construction site of the river-related construction project; S106, after the plot and the license space range data are processed in the coordinate system, based on the spatial position information in the plot, the candidate license set associated with the plot is filtered out from the license space range data through spatial retrieval; S108, calculating the spatial relationship between the plot and each license in the candidate license set, generating the associated license set, and for each license type in the associated license set, respectively calculating the type compliance, position compliance and area compliance of the plot and the license; S108, calculating the spatial relationship between the plot and each license in the candidate license set, generating the associated license set, and for each license type in the associated license set, respectively calculating the type compliance, position compliance and area compliance of the plot and the license; S110, the type conformity, location conformity and area conformity are weighted and summed according to preset weights to generate a conformity weighted score for each permit, and all conformity weighted scores of the associated permit set are traversed, and the highest score is determined as the final approval conformity evaluation result of the map patch.

[0026] The following example illustrates a river-related construction project: a wharf construction project. The wharf's permit information includes its type as "wharf" and the permitted construction area as a two-dimensional polygon. Satellite remote sensing imagery interpretation yields the actual construction data of the wharf, also classified as a "wharf," with its spatial location information consisting of a series of coordinate points forming an irregular two-dimensional polygon.

[0027] First, the permitted spatial extent data for the wharf construction project is obtained. The project type data is "wharf," and the spatial extent data is a set of two-dimensional polygon coordinates representing the permitted construction area. Simultaneously, image data of the construction site, i.e., image data of the actual wharf construction status obtained through remote sensing image interpretation, is acquired. The image data and the permitted spatial extent data are then processed to unify their coordinate systems, transforming them to the same coordinate system.

[0028] Next, based on the spatial location information in the map features, a candidate set of permits associated with the map features is selected from the permit spatial range data through spatial retrieval. For example, assuming there are multiple permit projects, by calculating the spatial relationship between the map features and each permit, permits that may be associated with the map features are selected to form a candidate permit set. For each type of permit in the associated permit set, the type conformity, location conformity, and area conformity between the map feature and the permit are calculated respectively.

[0029] In this embodiment, for patch S, its associated license set has a license scope L, whose type is "dock". The type conformity is... If another license exists Its type is "channel improvement". If "channel improvement" includes wharves, then the type compatibility coefficient can be set according to the business rules. If so, the type conformity is 0.6.

[0030] For calculating the positional compliance, we can first calculate the centroids CS and CL of the patch S and the permissible range L, for example, the distance between the patch centroid and the permissible range centroid. Meters, the maximum distance between any point within the permitted range and the centroid of the permitted range. Meters, attenuation coefficient Substitute into the formula For area conformity, assuming that the area of the plot is 8000 square meters, the area of the permitted range is 10000 square meters, the intersecting area of the plot and the permitted range is 7500 square meters, and the difference set area is 500 square meters, then The preset weights are, for example, , , The conformity weighted score is All conformity weighted scores of the associated permitted set are traversed, and assuming that 0.863 is the highest score, the final approval conformity evaluation result of the plot is determined as 0.863, and the approval conformity evaluation of the river-related construction project is completed.

[0031] Based on the content of the above embodiment, as an optional embodiment, the river-related construction project approval conformity evaluation provided by the present application comprises the following steps: based on the spatial position information in the plot, a minimum circumscribed rectangle of the plot is calculated; and a spatial intersection operation is performed between the minimum circumscribed rectangle and a permitted spatial range data set to obtain an intersecting candidate permitted set.

[0032] In the present embodiment, the minimum circumscribed rectangle of the plot is calculated based on the spatial position information in the plot. Figure 2 A schematic diagram of a plot minimum circumscribed rectangle is shown according to an optional embodiment of the present application, as shown in Figure 2 The plot is an irregular polygon, and its minimum circumscribed rectangle is obtained through geometric calculation, which can completely contain the plot and has the minimum area. Then, the spatial intersection operation is performed between the minimum circumscribed rectangle and the permitted spatial range data set to obtain the intersecting candidate permitted set. For example, assuming that there are 100 permitted projects, 10 permits intersecting with the minimum circumscribed rectangle of the plot are selected as the candidate permitted set through the intersection operation between the minimum circumscribed rectangle of the plot and the spatial range of each permit, so that the subsequent detailed spatial relationship calculation only needs to be performed on the 10 permits, which greatly improves the efficiency.

[0033] Based on the content of the above embodiment, as an optional embodiment, the river-related construction project approval conformity evaluation provided by the present application comprises the following steps: based on the spatial position information in the plot, a minimum circumscribed rectangle of the plot is calculated; and a spatial intersection operation is performed between the minimum circumscribed rectangle and a permitted spatial range data set to obtain an intersecting candidate permitted set.

[0034] Figure 3 A schematic diagram of a plot minimum circumscribed rectangle is shown according to an optional embodiment of the present application, as shown in Figure 3As shown, in this embodiment, the spatial relationship between the patch and each license in the candidate license set is calculated, and it is determined whether they intersect. The intersecting licenses are identified as associated licenses, and an associated license set is generated. For example, for each license in the candidate license set, the spatial relationship between the patch and the license is determined by a spatial analysis algorithm. If the spatial relationship between the patch and license L is intersecting, then license L is included in the associated license set, and the associated license set is finally obtained for further calculation of compliance.

[0035] Based on the above embodiments, as an optional embodiment, in the evaluation of the compliance of river-related construction projects provided by this invention, when calculating the type compliance, if the map patch type and the permit type are completely matched, such as the map patch type being "wharf" and the permit type also being "wharf," then the type compliance is 1. If the map patch type and the permit type are partially incompatible, for example, the map patch type being "road" and the permit type being "wharf," then the type compliance is 0. If the map patch type and the permit type are partially compatible, for example, the permit type being "waterway improvement," which includes multiple sub-projects such as wharfs and revetments, and the map patch type being "wharf," then a type compatibility coefficient α = 0.6 can be set, in which case the type compliance is 0.6.

[0036] Optionally, the following mathematical formula is used to quantify whether the land cover type of patch S belongs to the permitted type L:

[0037] Where α is the type compatibility coefficient, which is defined according to business rules and is set to 0.6 by default.

[0038] Based on the above embodiments, as an optional embodiment, the steps for obtaining the location compliance in the approval compliance evaluation of river-related construction projects provided by the present invention include: Obtain the Euclidean distance between the centroid of the patch and the centroid of the permitted area, as well as the maximum distance between any point on the permitted area and the centroid of the permitted area; The positional conformity is determined based on the Euclidean distance of the centroid of the permitted range and the maximum distance between any point on the permitted range and the centroid of the permitted range; The specific method for determining the positional compliance is as follows:

[0039] in, For the image patch, Within the scope of the license, Let L be the maximum distance between any point on the permissible range L and the centroid of the permissible range L. , The attenuation coefficient ( > >0), controls distance sensitivity. To attenuate the base, Suitable for Punitive severe attenuation.

[0040] In this embodiment, Figure 4 Fig. 1 illustrates a framework diagram of optional one calculation of the distance between the centroid of the map spot and the license range according to the embodiments of the present application, as shown, the compliance is analyzed by determining the positional relationship between the map spot and its associated license. Including distance, positional relationship, etc. Figure 4

[0041] The calculation of the positional compliance adopts different methods according to the spatial data form of the license.

[0042] For example, form 1: When the spatial data form of the license is a location point (single), that is, the license location point, only the positional compliance can be roughly calculated. The position of the license location point (single point) and the map spot can be three kinds: 1, the license location point is in the map spot edge line, and the compliance is determined as a preset value 1; 2, the license location point is on the map spot edge line, and the compliance is determined as a preset value 2; 3, the license location point is outside the map spot edge line, and the compliance is determined as 0.

[0043] Form 2: When the spatial data form of the license is a planar polygon, that is, the license range, the positional compliance can be calculated more accurately, and the distance compliance is calculated. Specifically as follows: The input conditions of the map spot and the license range are both two-dimensional spatial data, and the Euclidean distance of the centroids of the two is calculated. Figure 5 Fig. 1 illustrates a framework diagram of optional one calculation of the distance between the centroid of the map spot and the license range according to the embodiments of the present application, as shown, the compliance is analyzed by determining the positional relationship between the map spot and its associated license. Including distance, positional relationship, etc. Figure 5 As shown, the areas of the planar polygons of the map spot S and the license range L are calculated respectively, and the polygon vertices The area is:

[0044] The centroids CS and CL of the planar polygons of the map spot S and the license range L are calculated respectively, and the centroid calculation formula is:

[0045]

[0046] The Euclidean distance between the centroids of the planar polygons of the map spot S and the license range L is calculated (where n is the spatial data dimension, and 2 is taken) :

[0047] ​Computing the permitted range The maximum distance between any point on the planar polygon and the centroid:

[0048] Wherein is any point on the permitted range .

[0049] Computing the position compliance:

[0050] Wherein , is the attenuation coefficient (a > 0) that controls the distance sensitivity. is the basic attenuation, and is the punitive sharp attenuation suitable for .

[0051] Physical meaning: the closer the distance, the higher the score (tending to 1); the farther the distance, the lower the score (tending to 0).

[0052] Based on the content of the above embodiments, as an optional embodiment, the application provides a method for obtaining the area compliance in the evaluation of the river-related construction project approval compliance, comprising the following steps: Calculating the intersection area and the difference set area of the graph and the permitted range; Determining the area compliance according to the intersection area and the difference set area; The specific determination method of the area compliance is:

[0053] Wherein, is the graph, is the permitted range, is the intersection area, is the difference set area, is the area calculation formula, is the intersection area, is the difference set area In this embodiment, Figure 6 a schematic diagram of the difference set calculation and the intersection calculation of the graph and the permitted range according to an optional embodiment of the application is shown, as shown in Figure 6 , the area coverage of the graph S in the permitted L range is quantitatively evaluated to calculate the proportion of the intersection and difference set area in the total area of the permitted L range. Wherein, the graph and the permit are not empty.

[0054] For example, the part of the planar polygon of the graph S that coincides with the planar polygon of the permitted range L is defined as the intersection area ,

[0055] For example, defining the difference region. The region S, a polygonal area in the image, is independent of the permissible range polygon L; that is, the region in S that does not overlap with L.

[0056] The specific method for determining the area is as follows:

[0057] Then calculate the area compliance:

[0058] in, For the purpose of the image, Within the scope of the license, The intersection area For the difference set region, Here is the formula for calculating the area. The area of ​​intersection. The area of ​​the difference set. The area within the permitted range.

[0059] Finally, the type conformity, location conformity, and area conformity are weighted and summed according to preset weights to generate a conformity weighted score for each permit. All conformity weighted scores of the associated permit set are traversed, and the highest score is determined as the final approval conformity evaluation result of the map patch.

[0060] In this embodiment, a weighted score for compliance is calculated based on the weight of each compliance degree.

[0061]

[0062] in, For type weights, For positional weights, It is an area weight, and satisfies ; End of license set After traversal, the highest weighted score of compliance is taken as the permissible compliance score of the current patch, as shown in the following formula: .

[0063] In summary, the evaluation method for the compliance of river-related construction projects approved in this invention transforms the process, which originally relied on manual judgment, into objective numerical calculations through mathematical models and spatial computing technology. This greatly improves the efficiency and accuracy of the evaluation, reduces errors caused by subjective factors, and provides regulatory authorities with a scientific and efficient basis for decision-making.
