[0002] With the acceleration of urbanization, land use types are increasingly complex, covering wetlands, farmland, industrial land, etc. In order to reduce the damage to humidity and farmland caused by newly built buildings or newly repaired roads, the area of wetlands and farmland occupied by buildings and roads needs to be considered when planning buildings and roads.

[0053] Figure 1This is a flowchart illustrating a occupancy statistics method provided in an embodiment of the present invention. This embodiment is applicable to situations requiring automatic occupancy statistics. The method can be executed by an occupancy statistics device, such as... Figure 1 As shown, the specific steps include the following:

[0054] Step 110: Construct the layer to be analyzed based on the file package to be analyzed.

[0055] To minimize the impact of planned construction of new buildings or roads on existing land uses such as wetlands and farmland, the encroachment of planned land use on existing land must be considered during land use planning. In geographic information applications, buildings, roads, wetlands, farmland, and industrial land can all be represented by layers. The encroachment of planned land use on existing land can be determined by the overlap area between layers.

[0056] The file package to be analyzed can be understood as a building design file package or road design file package drawn using geographic information applications. For example, the file package to be analyzed can be a Shapefile package, which is usually compressed into ZIP or RAR format. The layer to be analyzed can be understood as the layer corresponding to the planned land use.

[0057] Specifically, the first step is to decompress the file package to be analyzed, obtaining the shape file, shape index file, and attribute table file contained within it. For example, by decompressing the Shapefile package, you can obtain .shp files (shape files), .shx files (shape index files), and .dbf files (attribute table files). The .shp file stores the geometric data of the features (spatial coordinate information of points, lines, polygons, etc.) and is the core data carrier of the Shapefile package. The .shx file records the offset and length of each feature in the .shp file, used for quickly locating and reading the geometric data in the .shp file, improving data access efficiency. The .dbf file stores the attribute information of each feature in the .shp file (such as name, number, value, etc.), using the dBASE database format, with rows corresponding to a feature in the .shp file and columns corresponding to attribute fields.

[0058] Furthermore, the layer to be analyzed can be constructed based on the shape file, shape index file, and attribute table file.

[0059] In one embodiment, step 110 may specifically include:

[0060] An initial layer is generated based on the shape files contained in the file package to be analyzed; the attribute information corresponding to each element in the initial layer is determined based on the shape index file contained in the file package to be analyzed in the attribute table file contained in the file package to be analyzed; the elements in the initial layer are adjusted according to the attribute information corresponding to each element in the initial layer to obtain the layer to be analyzed.

[0061] Specifically, an initial layer can be generated from a shape file. The initial layer consists of multiple features, each with different positional, identification, and attribute information. To improve the accuracy of the layers, after generating the initial layer, each feature can be adjusted based on its offset and length in the shape index file and the attribute information of each feature in the attribute table file to obtain the layer to be analyzed.

[0062] In this embodiment of the invention, the file package to be analyzed is parsed to determine the shape file, shape index file, and attribute table file contained in the file package. An initial layer is constructed based on the shape file, and the initial layer is optimized based on the shape index file and attribute table file to obtain the layer to be analyzed, thereby achieving the construction of a more accurate layer to be analyzed.

[0063] Step 120: Obtain each of the business layers; based on the spatial relationship between the business layers, overlay and display each of the business layers on the underlying map.

[0064] Among them, the business layer can be understood as the layer corresponding to the existing land use, such as wetland map layer, cultivated land map layer, and industrial land map layer.

[0065] Specifically, the first step is to obtain the various business layers, which means obtaining the layers corresponding to existing land use within the current area. For fixed areas, the layers of existing land use within them have already been pre-generated and stored on servers or in databases. Therefore, based on the location information of the current area, the corresponding business layer for the current area can be obtained from the Spatial Database Engine (SDE) used to manage geospatial data in the region to which the current area belongs. The SDE databases corresponding to each region can publish mapserver service interfaces for data access. Specifically, the mapserver service interface can be accessed based on the coordinate range of the current area to obtain the business layer for the current area.

[0066] For a fixed area, wetlands, farmland, and industrial land are usually scattered within the area. To improve the efficiency of determining the overlapping area between different types of business land and planned land, the business layers corresponding to existing land can be projected onto the underlying map. A business layer consists of all area layers corresponding to the business within the current area; for example, the wetland map layer includes all wetlands within the current area. Therefore, each business layer of the current area can be mapped onto the underlying map of the current area. The underlying map of the current area can be understood as a satellite map of the current area. Specifically, the business layers can be overlaid on the underlying map according to their spatial relationships, i.e., they can be overlaid in ascending order. Of course, for business layers with the same height information, they can be overlaid in a random order, for example, in the order of wetlands-farmland-forest-industrial land, thus constructing a map containing wetland, farmland, forest, and industrial land layers.

[0067] It should be noted that if all business layers are obtained from the same database or service interface, the business coordinate systems corresponding to each business layer are usually consistent. In this case, each business layer can be directly mapped onto the underlying map. However, if the business layers are obtained from different databases or service interfaces, the business coordinate systems of the business layers obtained from different databases or service interfaces may be inconsistent. In this case, coordinate system transformation of the business layers is required. Specifically, the business coordinate system corresponding to the majority of business layers can be determined as the target coordinate system. Business layers corresponding to other coordinate systems are then transformed to the target coordinate system. After the transformation is completed, the business layers transformed to the unified coordinate system are mapped onto the underlying map.

[0068] In this embodiment of the invention, by acquiring each business layer in the current area and overlaying each business layer on the underlying map according to the spatial relationship between them, the business layers can be quickly acquired and the map containing the business layers can be quickly constructed, thus realizing the visualization of the business layers.

[0069] Step 130: Based on the spatial relationship between the projection coordinate system in the projection information file contained in the file package to be analyzed and the business coordinate system corresponding to each business layer, transform the layer to be analyzed to the business coordinate system; project the transformed layer to be analyzed onto the business layer.

[0070] To determine the overlapping area between the layer to be analyzed and the business layer, it is necessary to maintain the consistency of the reference coordinate system between the two layers. The business layer is usually constructed based on the business coordinate system, so the layer to be analyzed needs to be transformed to the business coordinate system.

[0071] Specifically, the analysis file package also includes a projection information file, such as a .prj file, to store the coordinate system and projection parameters, ensuring that the layer can be correctly positioned on the Earth's surface. If the coordinate system in the projection information file is consistent with the business coordinate system, then the coordinate system of the layer to be analyzed is consistent with the coordinate system of the business layer, requiring no conversion, and the layer to be analyzed can be directly projected onto the underlying map that has already projected multiple business layers. If the coordinate system in the projection information file is inconsistent with the business coordinate system, then the coordinate system of the layer to be analyzed is inconsistent with the coordinate system of the business layer. In this case, a coordinate system transformation of the layer to be analyzed is required. Specifically, based on the spatial relationship between the coordinate system of the layer to be analyzed and the business coordinate system, the layer to be analyzed can be transformed to the business coordinate system. Then, the layer to be analyzed, transformed to the business coordinate system, can be projected onto the business layer, i.e., onto the underlying map that has already projected multiple business layers.

[0072] For example, if the coordinate system of the layer to be analyzed is EPSG:4547 and the business coordinate system is Geodetic 2000, then after constructing the layer to be analyzed, the layer to be analyzed can be converted to Geodetic 2000 based on the spatial relationship between EPSG:4547 and Geodetic 2000.

[0073] In practical applications, a base map with the layer to be analyzed and the business layer can be overlaid on a preset interface to achieve simultaneous visualization of the two layers.

[0074] In this embodiment of the invention, after converting the layer to be analyzed to be consistent with the coordinate system of the business layer, the layer to be analyzed is projected onto the business layer, thereby achieving effective superposition of the layer to be analyzed and the business layer and improving the accuracy of determining the overlapping area of ​​the layer to be analyzed and the business layer.

[0075] Step 140: Perform intersection analysis on the layer to be analyzed and each business layer to determine the overlapping area between the layer to be analyzed and each business layer.

[0076] The spatial reference of the layer to be analyzed is consistent with that of each of the business layers.

[0077] In one embodiment, step 140 may specifically include:

[0078] By performing asymmetric intersection analysis on the layer to be analyzed and each of the business layers, the overlapping portion of the layer to be analyzed and each of the business layers is extracted to obtain the overlapping region.

[0079] Specifically, the underlying map, overlaid with the layer to be analyzed and each business layer, can be input into the asymmetric intersection analysis engine. The engine can use the layer to be analyzed as the input layer and each business layer as the intersection layer, performing asymmetric intersection analysis on the input and intersection layers. Specifically, the `overlay_layers_asymmetric_intersect` tool can be called to perform the asymmetric intersection analysis, extracting and retaining the overlapping portions of the layer to be analyzed with each business layer, thus obtaining the overlapping area. The resulting overlapping area represents the portion where the layer to be analyzed overlaps with all the business layers.

[0080] In this embodiment of the invention, by performing asymmetric intersection analysis on the layer to be analyzed and each business layer, the overlapping area between the layer to be analyzed and each business layer is determined, thereby achieving rapid determination of the overlapping area.

[0081] Step 150: Determine the occupancy statistics result based on the area of ​​each overlapping region and the occupancy statistics method.

[0082] In one implementation, the occupancy statistics method is based on business type; accordingly, step 150 may specifically include:

[0083] Determine the area of ​​each overlapping region and the service type of the corresponding service layer; obtain the occupied area of ​​each service type by superimposing the areas of each overlapping region corresponding to each service type; determine the occupied area of ​​each service type as the occupancy statistics result.

[0084] The occupation statistics method based on business type can be understood as calculating the area of ​​overlapping areas according to business type. For example, we can determine the occupation area of ​​wetlands, cultivated land, and industrial land respectively.

[0085] Specifically, first, the business layer corresponding to each overlapping area can be determined, then the business type corresponding to each business layer can be determined, and finally, the business type corresponding to each overlapping area can be determined. Of course, the overlapping area corresponding to each business type can also be determined.

[0086] When determining the area of ​​each overlapping region, the geodeticAreaCal tool can be used to calculate the geometric area of ​​the overlapping region. For each business type, the area of ​​the overlapping region corresponding to each business type can be calculated to obtain the overlapping area corresponding to each business type. That is, the overlapping area corresponding to wetlands, cultivated land, and industrial land can be obtained. Then, the overlapping areas corresponding to wetlands, cultivated land, and industrial land can be determined as the wetland occupied area, cultivated land occupied area, and industrial land occupied area, respectively.

[0087] Furthermore, wetlands can be further subdivided into national-level wetlands, provincial-level wetlands, wetland parks, etc., and cultivated land can be further subdivided into red-line cultivated land, important cultivated land, etc. To conduct more accurate encroachment statistics, the corresponding business layer for each overlapping area can be determined. When the business type corresponding to the business layer is wetland, the wetland type is further determined, and then the overlapping areas corresponding to each wetland type can be determined. Finally, by summing the areas of the overlapping areas corresponding to each wetland type, the encroachment area corresponding to each wetland type can be determined. Similarly, when the business type corresponding to the business layer is cultivated land, the cultivated land type is further determined, and then the overlapping areas corresponding to each cultivated land type can be determined. Finally, by summing the areas of the overlapping areas corresponding to each cultivated land type, the encroachment area corresponding to each cultivated land type can be determined.

[0088] Of course, ecologically sensitive areas can be understood as areas such as wetlands and arable land that require ecological protection, while other areas are considered non-ecologically sensitive areas. The method for calculating land occupation is as follows: when calculating land occupation by ecologically sensitive areas, after determining the areas occupied by wetlands, arable land, and industrial land, the ecologically sensitive land occupation area can be further determined based on the wetland and arable land occupation areas, and the non-ecologically sensitive land occupation area can be determined based on the land occupation areas of other areas.

[0089] In practical applications, after determining the asymmetric intersection results by performing asymmetric intersection analysis on the layer to be analyzed and each business layer—that is, determining the overlapping areas between the layer to be analyzed and each business layer—the write2POSTGISSDEDB tool can be called to write the asymmetric intersection results into the business SDE database. The SDE database supports distributed storage and transaction processing. It can perform multidimensional statistics on the asymmetric intersection results by executing SQL to generate structured occupancy statistics. For example, by executing `SELECT land_type, SUM(area_sqm) FROM overlap_resultGROUP BY land_type`, the occupancy statistics can be obtained.

[0090] Furthermore, occupancy statistics results can be stored in the form of a storage table. For example, when the occupancy statistics are based on business type, the occupancy statistics results can be stored in the storage table in the form of business type - occupancy area, and the storage table can be displayed on the result display interface. Specifically, the occupancy statistics results can be stored and displayed based on Apache Echarts (a data visualization chart library based on JavaScript).

[0091] Of course, users can obtain the offline occupancy statistics file by clicking the download control in the results display interface.

[0092] In this embodiment of the invention, the area of ​​each overlapping region is statistically analyzed according to the occupancy statistics method, and the occupancy statistics result corresponding to the occupancy statistics method is determined, thereby realizing automated occupancy statistics.

[0093] Step 160: After receiving the trigger information for the service type, display the corresponding overlapping area based on the preset mark display method.

[0094] Specifically, the interface displays a storage table that stores occupancy statistics by business type and occupancy area. When a user clicks the control corresponding to a business type, trigger information for that business type is generated. Upon receiving this trigger information, the overlapping area corresponding to the business type can be displayed using a preset marking method. For example, the overlapping area can be displayed using a preset color, making it easier for users to observe the occupancy of the layer under analysis over a specific business layer, i.e., to observe the occupancy of planned land over various types of current land use.

[0095] In practical applications, the OpenLayers framework can be used to highlight overlapping areas on the underlying map, allowing users to easily observe the occupancy of the specific layer being analyzed relative to the business layer. Through the map-data linkage technology between OpenLayers and ECharts, real-time linkage between map highlighting and chart filtering can be achieved, improving visualization efficiency.

[0096] In this embodiment of the invention, the user clicks on the control corresponding to the business type to trigger the trigger information for the business type. Based on the trigger information, the overlapping area corresponding to the business type is displayed in color, which makes it easier for the user to observe the occupancy of the layer to be analyzed on the specific business layer.

[0097] The occupancy statistics method provided in this invention includes: constructing an analysis layer based on a file package to be analyzed; obtaining each of the business layers; overlaying each of the business layers on a base map according to the spatial relationship between them; converting the analysis layer to the business coordinate system according to the spatial relationship between the projection coordinate system in the projection information file contained in the file package to be analyzed and the business coordinate system corresponding to each of the business layers; projecting the analysis layer converted to the business coordinate system onto the business layers; performing intersection analysis on the analysis layer and each business layer to determine the overlapping area between the analysis layer and each of the business layers; and determining the occupancy statistics result based on the area of ​​each overlapping area and the occupancy statistics method. Upon receiving trigger information for the business type, the corresponding overlapping area is displayed based on a preset marker display method. The above technical solution firstly identifies the shape file, shape index file, and attribute table file contained in the file package to be analyzed by parsing it. An initial layer is constructed based on the shape file, and the initial layer is optimized using the shape index file and attribute table file to obtain the layer to be analyzed, thus constructing a more accurate layer. Secondly, the spatial relationships between various business layers within the current area are used to overlay and display these layers on the underlying map, enabling rapid construction of a map containing business layers and further enabling visualization of these layers. Then, the layer to be analyzed, converted to a coordinate system consistent with the business layers, is projected onto the business layers, achieving effective overlay and improving the accuracy of determining the overlapping areas. Furthermore, asymmetric intersection analysis is performed on the layer to be analyzed and each business layer to determine the overlapping areas, enabling rapid identification of these areas. The area of ​​each overlapping area can also be statistically analyzed using a occupancy statistics method to determine the corresponding occupancy statistics results. Finally, the occupancy statistics results can be displayed using visual charts, achieving full automation of the occupancy statistics process and improving efficiency. Furthermore, users do not need to master geographic information applications or underlying technologies; they can complete occupancy statistical analysis through the front-end interface, thus lowering the technical threshold.

[0098] In addition, by having the user click on the control corresponding to the business type, trigger information for that business type is generated. Based on the trigger information, the overlapping areas corresponding to the business types are displayed in color. The underlying map with the layer to be analyzed and the business layer overlaid supports zooming and click query. Combined with visualization charts, "map-data linkage" can be achieved, which is more intuitive than traditional static maps and makes it easier for users to observe the occupancy of the layer to be analyzed on the specific business layer.
