[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0024] The embodiment of the present application provides a data display method based on land and resources survey, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited to this. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and the embodiment of the present application does not limit this. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104 and step S105, wherein: Step S101: Obtain the land class patches corresponding to the target range uploaded by each county-level terminal, perform preprocessing on each land class patch, and obtain multiple target land class patches, wherein the preprocessing is used to normalize the data uploaded by different county-level terminals.

[0025] For the embodiments of the present application, each county, as the grassroots unit that directly manages regional natural resources, has the most direct understanding and grasp of the actual situation of the land type map corresponding to the target scope. Therefore, by uploading the land type map corresponding to the target scope through the county-level terminal, the accuracy and timeliness of the data can be ensured, reflecting the latest land use conditions and changes. Land type map refers to a single land type plot divided by administrative boundaries, ownership boundaries, and linear features. Land type map is the basic unit in land use, used to describe and record land type, scope, area and other information. Land type map usually exists in the form of data, including but not limited to: basic information (for example, map ID, area, perimeter), spatial location information (for example, map number, map sheet number, geometric shape), land type information (for example, land type code, land type name), etc.

[0026] However, since different county-level terminals may use different data formats, coordinate systems or data standards to collect and store land type spots, the diversity of land type spots may cause difficulties in data integration and analysis, and even data incompatibility. Therefore, preprocessing is performed based on each land type spot to obtain multiple target land type spots, wherein the preprocessing is used to standardize the data uploaded by different county-level terminals. There are many ways to implement preprocessing, and the embodiments of the present application are no longer limited. In one feasible method, classification is performed based on multiple land type spots to obtain the spot type corresponding to each land type spot; according to the spot type, multiple land type spots are sent to the corresponding computing resources under the distributed architecture, wherein land type spots corresponding to the same spot type are sent to the same computing resource; the preprocessing process corresponding to each spot type is obtained, and the computing resources are controlled to preprocess each land type spot according to the preprocessing process to obtain multiple target land type spots.

[0027] Step S102: Draw a base map based on multiple target land type patches to obtain a land type patch map, wherein the land type patch map graphically displays multi-dimensional information corresponding to the distribution, range, form and quantity of the land type patches.

[0028] For the embodiment of the present application, the drawing purpose and accuracy requirements of the base map drawing are obtained, and a suitable base map is selected as the basis for drawing. The base map can be a topographic map, an administrative division map, etc., and according to the characteristics of the base map and the display requirements of the target land class map, the scale, legend, color scheme and other parameters of the drawing are set to ensure the clarity and readability of the base map drawing. Then, the pre-processed multiple target land class spots are imported into the drawing software as drawing data, and the drawing tools in the drawing software are controlled to draw the boundaries and fill colors of each target land class spot according to the multiple target land class spots, ensuring that the boundaries of the spots are consistent with the original data, and the fill colors can clearly distinguish different land classes to obtain the land class map. Of course, necessary attribute information can also be added to the land class map, for example, land class code, land class name, area, etc., and these attribute information can be displayed in the form of text annotation, legend description or data table. Land class map is an important basic data for land use planning and management. By drawing land class map, the distribution, scope, form and quantity of different land types can be clearly displayed, providing intuitive and accurate data support for land use planning, land management, environmental monitoring and other fields.

[0029] Step S103: Control the drone to perform aerial photography detection on the monitoring area corresponding to the land type map, obtain the remote sensing image sent back by the drone, perform land use analysis based on the remote sensing image, and determine the land use status map.

[0030] For the embodiment of the present application, in order to achieve dynamic management of land use and provide a scientific basis for land use planning and policy formulation, the drone is controlled to conduct aerial photography detection of the monitoring area to obtain the current land use status of the monitoring area corresponding to the land type map. Accurately judging the land type and status helps to optimize the land use structure, improve land efficiency, and achieve sustainable use of land resources.

[0031] Specifically, according to the land type map, the scope of the area to be monitored is clearly defined, including geographical coordinates, area and other information. Then, according to the monitoring area, the drone model suitable for the aerial photography task is selected to ensure that its flight stability, endurance, load capacity and other requirements are met, and the drone is equipped with remote sensing equipment such as high-resolution cameras and infrared imaging systems to obtain high-quality remote sensing images. Then, according to the topography, climatic conditions and other factors of the monitoring area, a detailed flight plan is formulated, where the flight plan includes but is not limited to: flight route, flight altitude, flight speed, shooting parameters, etc., to ensure the coverage and clarity of the aerial images. Then, according to the flight plan, the drone is controlled to conduct aerial photography detection of the monitoring area corresponding to the land type map. During the flight, the high-resolution camera and other remote sensing equipment carried by the drone will take real-time remote sensing images of the monitoring area, and transmit the captured remote sensing image data to the electronic equipment in real time. Then, after obtaining the remote sensing images sent back by the drone, the received remote sensing image data is pre-processed, including image enhancement, denoising, correction and other processing steps to improve the clarity and accuracy of the remote sensing images, providing a basis for subsequent land use analysis. After that, remote sensing image classification technology is used to classify the land use types in the monitoring area, where land use types include but are not limited to: cultivated land, forest land, grassland, construction land and other categories. Then, multi-dimensional land use analysis is performed based on the classified remote sensing images to determine the land use analysis results, where multi-dimensional land use analysis can be analyzed from multiple aspects such as the quantity, distribution, and structure of land use. Finally, based on the results of the land use analysis, a land use status map is produced, in which the distribution and scope of different land use types, as well as the current characteristics of land use, are clearly displayed.

[0032] Step S104: Acquire land title confirmation information, confirm the ownership based on the land classification map and the land title confirmation information, and obtain the land title confirmation result.

[0033] For the embodiment of the present application, land confirmation information is an important basis for confirming land ownership, including but not limited to: land ownership certificate, land contract, land registration book, etc. Then, the land confirmation information is digitized to extract key information from documents such as land ownership certificate and land contract, such as land location, area, and right holder. Then, the land type map is vectorized using GIS software to extract information such as the boundary and area of ​​the map, and the vectorized land type map is superimposed with the key information extracted from the land confirmation information, and the superimposed data is matched in terms of position and area. When the land type map is consistent with the land confirmation information in terms of both position and area, it indicates that the ownership of the land has been confirmed and is marked as confirmed; when the land type map is inconsistent with the land confirmation information in terms of position and area, it indicates that the ownership of the land is abnormal and is marked as unconfirmed. Finally, the ownership confirmation of each piece of land is combined to obtain the land ownership confirmation result.

[0034] Step S105: Perform map fusion based on the land type map, the land use status map and the land ownership confirmation result to obtain a panoramic map of land resources.

[0035] For the embodiments of the present application, the data coordinates of the land type map, the current land use map, and the land ownership confirmation results are unified into the same coordinate system, for example, WGS84, CGCS2000, etc., and the data format is converted into a format suitable for map fusion and processing, for example, Shapefile, GeoJSON, etc. Furthermore, the land type map, the current land use map, and the land ownership confirmation results are superimposed as different layers, and the fused map is visualized using different colors, symbols, and annotations according to the visualization needs of the panoramic map, so as to better display the information of the land and resources panoramic map. The use of a multi-layer superimposed land and resources panoramic map to intuitively display the spatial distribution, form, and mutual relationship of land and resources facilitates rapid understanding and analysis of data, and improves the readability and ease of use of the data.

[0036] It can be seen that in the embodiment of the present application, the land class spots corresponding to the target range uploaded by each county-level terminal are obtained, and preprocessing is performed based on each land class spot to obtain multiple target land class spots, wherein the preprocessing is used to normalize the data uploaded by different county-level terminals. Then, a base map is drawn based on multiple target land class spots to obtain a land class spot map, which can clearly display the distribution, scope, form and quantity of different land types, and provide intuitive and accurate data support for land use planning, land management, environmental monitoring and other fields. Then, the drone is controlled to perform aerial photography detection on the monitoring area corresponding to the land class spot map, and land use analysis is performed based on the remote sensing images sent back by the drone to determine the current land use map; at the same time, ownership confirmation is performed based on the land class spot map and land title confirmation information to obtain the land title confirmation result. Finally, map fusion is performed based on the land class spot map, the current land use map and the land title confirmation result to obtain a panoramic view of land resources. A panoramic map of land and resources with multiple layers of superposition is used to intuitively display the spatial distribution, form and mutual relationship of land and resources, which facilitates the rapid understanding and analysis of data and improves the readability and ease of use of the data.

[0037] Furthermore, in order to ensure that the information in the panoramic map is always consistent with the actual situation, in the embodiment of the present application, after the map fusion is performed based on the land type map, the land use status map and the land ownership confirmation result to obtain the land resources panoramic map, it also includes: When an update instruction carrying resource update information is detected, an update target analysis is performed based on the resource update information to determine an update object, wherein the update object is at least one of a land type map, a land use status map, and a land ownership confirmation result; Based on the resource update information, the update object is dynamically updated to obtain the adjusted update object, and based on the adjusted update object, the land and resources panoramic map is dynamically updated to obtain the adjusted land and resources panoramic map.

[0038] For the embodiment of the present application, the land and resources panoramic map is an important tool for reflecting the current status, ownership and classification of land resources. The timeliness and accuracy of its data are crucial. However, with the rapid development of social economy and the acceleration of urbanization, there will be a need to change land and resources information, such as changes in land use status, land transfer, expropriation, circulation, etc. Therefore, dynamic update technology is introduced to timely adjust the land and resources panoramic map according to the change needs of land and resources, ensure that the information in the panoramic map is always consistent with the actual situation, and provide reliable data support for land and resources management, urban planning, agricultural development and ecological environment protection.

[0039] Specifically, the electronic device will continuously monitor whether an update instruction carrying resource update information is received. When an update instruction carrying resource update information is detected, the update key information corresponding to the resource update is determined based on the resource update information, wherein the update key information includes but is not limited to: update type, update scope and update content, and the update key information in the resource update information and the update object are screened and located item by item to determine the update object, wherein the update object is at least one of the land class map, the land use status map and the land ownership confirmation result. Then, the update object is dynamically updated based on the update content in the resource update information to obtain the adjusted update object, and the dynamic update process will involve operations such as replacement, addition, deletion and modification of data. In order to ensure the accuracy and reliability of the adjusted update object, after the dynamic update is completed, the adjusted update object is subjected to data verification and validation. Finally, the adjusted update object is integrated with other parts of the land and resources panorama, and the integrated data is rendered using a map rendering engine to obtain the adjusted land and resources panorama, which is always consistent with the actual situation and accurately reflects the current status of land resource utilization, ownership and classification and other aspects of information.

[0040] It can be seen that in the embodiment of the present application, when an update instruction carrying resource update information is detected, an update target analysis is performed based on the resource update information to determine the update object. Then, the update object is dynamically updated based on the resource update information to obtain an adjusted update object, and the land and resources panorama is dynamically updated based on the adjusted update object to obtain an adjusted land and resources panorama. By introducing dynamic update technology, the land and resources panorama is adjusted in a timely manner according to the change requirements of land and resources, ensuring that the information in the panorama is always consistent with the actual situation, and providing reliable data support for land and resources management, urban planning, agricultural development, and ecological environmental protection.

[0041] Furthermore, in order to ensure the sustainable use of land resources and quickly and accurately identify the changed land resources, in the embodiment of the present application, after the map fusion is performed based on the land type map, the land use status map and the land ownership confirmation result to obtain the land resources panoramic map, it also includes: Obtain a panoramic view of historical land resources, conduct difference screening based on the panoramic view of land resources and the panoramic view of historical land resources, and determine differential land resources; Conduct compliance analysis based on historical resource information and current resource information corresponding to differential land resources, and determine resource compliance analysis results; When the result of resource compliance analysis is non-compliant, the different land resources will be marked in the national land resources panorama to facilitate the intuitive display of the distribution of non-compliant land resources.

[0042] For the embodiments of the present application, land resource information is a dynamically changing process, which will be affected by various factors such as nature, economy, equipment, etc. However, in the process of using land resources, there may be illegal occupation and abuse of land resources. In order to ensure the sustainable use of land resources, protect the ecological environment and cultivated land resources, quickly and accurately identify the changed land resources, conduct compliance analysis on the difference land resources, intuitively mark the non-compliant land resources, and promote the rational use and protection of land resources.

[0043] Specifically, the electronic device pre-stores a historical land resource panorama, which is a land resource panorama generated by the last land survey. Then, the current land resource panorama and the historical land resource panorama are registered to ensure the spatial consistency of the two, that is, by selecting the same geographical feature points for registration to improve the registration accuracy. Then, the difference detection is performed on the two registered land resource panorama maps, and the different land resource parts between the two are marked as differential land resources. Obtain the compliance standard, which is a judgment standard for land resource compliance formulated based on national laws and regulations, local policies, land use planning and other factors. Then, the current resource information of the differential land resources is matched with the compliance standard to determine the resource compliance analysis result, that is, if the current resource information matches the compliance standard successfully, the resource compliance analysis result is determined to be compliant; if the current resource information fails to match the compliance standard, the resource compliance analysis result is determined to be non-compliant. When the resource compliance analysis result is non-compliant, it indicates that the differential land resources are illegally occupied or abused. Therefore, the differential land resources are marked in the national land resources panorama to visually display the distribution of non-compliant land resources. Marking abnormal differential land resources helps regulatory authorities quickly understand the status quo and problems of land resource management, so that they can take corresponding measures to rectify and improve, and promote the rational use and protection of land resources.

[0044] It can be seen that in the embodiment of the present application, in order to ensure the sustainable use of land resources, protect the ecological environment and cultivated land resources, quickly and accurately identify the changed land resources, perform difference screening based on the land resources panorama and the historical land resources panorama, determine the difference land resources, and then perform compliance analysis based on the historical resource information and current resource information corresponding to the difference land resources to determine the resource compliance analysis result. When the resource compliance analysis result is non-compliant, the difference land resources are marked in the land resources panorama to facilitate the intuitive display of the distribution of non-compliant land resources. Compliance analysis is performed on the difference land resources, and non-compliant land resources are intuitively marked to promote the rational use and protection of land resources.

[0045] Furthermore, in order to improve the preprocessing efficiency of land class spots, make full use of the advantages of computing resources, and effectively avoid resource waste, in the embodiment of the present application, preprocessing is performed based on each land class spot to obtain multiple target land class spots, including: Based on the classification of multiple land type spots, the spot type corresponding to each land type spot is obtained; According to the patch type, multiple land class patches are sent to the corresponding computing resources under the distributed architecture, wherein the land class patches corresponding to the same patch type are sent to the same computing resource; The preprocessing process corresponding to each map type is obtained, and the computing resources are controlled to preprocess each land type map according to the preprocessing process to obtain multiple target land type maps.

[0046] For the embodiment of the present application, there are multiple types of spots corresponding to land type spots, including but not limited to regular spots, narrow spots, and small spots, etc. Therefore, when preprocessing multiple land type spots, classification and division based on multiple land type spots are preferred to obtain the type of spots corresponding to each land type spot. The specific implementation process for classification and division is as follows: graphically display the land type spots in data form to obtain graphical land type spots, and then use image processing technology to extract the shape features and texture features of each land type spot. The shape features include but are not limited to: boundary contour, aspect ratio, area, etc.; the texture features include but are not limited to: color distribution, texture pattern, etc. Furthermore, a patch type analysis is performed based on the extracted shape features and texture features to determine the patch type. That is, for land patches with regular shape features, the patch type is determined to be a regular patch, such as a land patch with a smooth boundary and a shape close to a rectangle or a circle; based on the aspect ratio in the shape features, land patches whose length is much greater than their width are identified, and the patch type is determined to be a long and narrow patch; based on the area value in the shape features, land patches whose area is less than the area threshold are identified, and the patch type is determined to be a small patch.

[0047] In order to improve the preprocessing efficiency of land class spots, make full use of the advantages of computing resources, and effectively avoid waste of resources, in an embodiment of the present application, computing resources are deployed in a distributed architecture, and multiple land class spots are sent to the corresponding computing resources under the distributed architecture according to the spot type, so as to realize parallel calculation and batch processing of preprocessing. Since the characteristics of land class spots of different spot types are different, the preprocessing operations to be performed will also be different. Therefore, the electronic device pre-stores the preprocessing processes corresponding to the different spot types. The preprocessing processes corresponding to the spot types can ensure that the target land class spots after preprocessing meet the requirements of subsequent base map drawing. Therefore, the preprocessing process corresponding to each spot type is obtained, and the computing resources are controlled to preprocess each land class spot according to the preprocessing process to obtain multiple target land class spots. Different preprocessing processes are adopted for different types of land class spots, which improves the accuracy of preprocessing and the consistency of the target land class spot format.

[0048] It can be seen that in the embodiment of the present application, in order to improve the preprocessing efficiency of land class spots, make full use of the advantages of computing resources, and effectively avoid resource waste, classification is performed based on multiple land class spots to obtain the spot type corresponding to each land class spot. Then, according to the spot type, multiple land class spots are sent to the corresponding computing resources under the distributed architecture, wherein the land class spots corresponding to the same spot type are sent to the same computing resource, and then, the preprocessing process corresponding to each spot type is obtained, and the computing resources are controlled to preprocess each land class spot according to the preprocessing process to obtain multiple target land class spots.

[0050] For the embodiments of the present application, in order to more realistically reflect the spatial distribution and morphological characteristics of land and resources and realize an all-round and multi-angle display of land and resources, through map fusion and three-dimensional modeling technology, the scattered land type maps, land use status maps, land ownership confirmation results, and terrain and building data are integrated into a land and resources panoramic map.

[0051] Specifically, using geographic information system technology, the land type map, land use status map and land ownership confirmation results are superimposed as different layers to ensure that the spatial relationship between the layers corresponds correctly. Then, according to the spatial position relationship, the attribute data of each layer is associated to ensure that each geographic entity has complete attribute information in the fused map, and a preliminary panorama is generated based on the fused map data. The preliminary panorama includes the geographic entities and attribute information of all layers to present a clear and accurate visual effect. Then, terrain data and building data are obtained. The terrain data includes but is not limited to: elevation data, geographic texture data, etc.; the building data includes but is not limited to: the geometric shape, size, location, texture and other information of the building. Then, a three-dimensional modeling software is used to build a terrain model, that is, a terrain grid is generated according to the elevation data, and terrain texture data is applied to improve the fidelity and accuracy of the terrain model; at the same time, a three-dimensional modeling software is used to build a building model, that is, the building shape is built according to the geometric shape of the building, and the building texture data is applied to refine and optimize the building. Then, the terrain model and the building model are integrated into a scene, and the position, size and direction of the model are adjusted to ensure the correct spatial relationship between them. Furthermore, the building model is embedded into the terrain model to ensure that the position, height and orientation of the building model are consistent with the terrain model, and the building model is optimized in detail, such as adding shadows, adjusting lighting effects, etc., to enhance the three-dimensional sense of the building. Then, the terrain model embedded with the building model is fused with the preliminary panorama, and the texture information of the panorama is applied to the terrain model through texture mapping, and the scale, rotation and position of the texture are adjusted to ensure that the texture matches the geometry of the terrain model. Finally, a panoramic map of land and resources is obtained, which more intuitively displays the spatial distribution and morphological characteristics of land resources, and helps to discover the utilization potential and problems of land resources. Of course, interactive design can also be introduced to allow users to freely explore the panoramic map of land and resources through operations such as zooming, rotating, and panning to enhance the user experience.

[0052] It can be seen that in the embodiment of the present application, the geographic information system technology is used to map the land type map, the land use status map and the land ownership confirmation results to generate a preliminary panoramic map. Then, three-dimensional modeling is performed based on the terrain data and the building data to obtain a terrain model and a building model. Finally, a visual fusion is performed based on the preliminary panoramic map, the terrain model and the building model to obtain a panoramic map of land and resources. Through map fusion and three-dimensional modeling technology, the scattered land type map, the land use status map, the land ownership confirmation results, and the terrain and building data are integrated into a panoramic map of land and resources. Through visual fusion, the panoramic map of land and resources can provide richer spatial information and more intuitive visual effects, which is helpful to discover the utilization potential and problems of land resources.

[0054] For the embodiment of the present application, the panoramic map of land and resources is imported into the VR platform, and according to the requirements of the VR platform, the panoramic map of land and resources is processed by format conversion, size adjustment, etc., and the modeling tools in the VR platform are used to construct a VR model of land and resources based on the panoramic map of land and resources, ensuring that the VR model is consistent with the actual scene in the panoramic map of land and resources, including but not limited to scenes such as terrain, landforms, and buildings. Of course, interactive functions such as hotspot annotation and information query can also be added to the VR model to facilitate the immersive experience of land and resources management personnel. Then, the land and resources management personnel wear VR equipment, enter the constructed VR model of land and resources, and interact with the VR model through the controller or gesture recognition function in the VR equipment. Through VR technology, an immersive experience method is provided for land and resources management personnel, which enhances the vividness and authenticity of the display of land and resources, and facilitates land and resources management personnel to more intuitively understand the utilization and potential of land resources.

[0055] Then, collect VR scene feedback information from land and resources management personnel in the VR scene, and the feedback information includes but is not limited to: the authenticity of the model, the convenience of interactive functions, and optimization suggestions for the scene. Then, optimize and adjust the VR model based on the VR scene feedback information to obtain an optimized VR model, where the dimensions of optimization and adjustment include but are not limited to: fine-tuning the terrain, landforms, buildings, etc. in the model to improve the authenticity of the model; improving and optimizing the interactive functions to improve the convenience of management personnel.
