[0051] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0052] The embodiments of the present application provide a data display method based on land and resources survey, which is executed by an electronic device. The electronic device can be a server or a terminal device. Among them, the server can be an independent physical server, a server cluster or a 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 notebook computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and the embodiments of the present application do not limit this, such as Figure 1As shown in the figure, the method includes step S101, step S102, step S103, step S104, and step S105, where:

[0053] Step S101: Obtain the land type patches corresponding to the target range uploaded by each county-level terminal, and perform preprocessing based on each land type patch to obtain multiple target land type patches. Among them, the preprocessing is used to standardize the data uploaded by different county-level terminals.

[0054] For the embodiments of the present application, each county, as a grass-roots unit directly managing regional natural resources, has the most direct understanding and grasp of the actual situation of the land type patches corresponding to the target range. Therefore, by uploading the land type patches corresponding to the target range through the county-level terminal, the accuracy and timeliness of the data can be ensured, and the latest land use status and changes can be reflected. A land type patch refers to a single land type plot divided by administrative boundaries, ownership boundaries, linear features, etc. Land type patches are the basic units in land use, used to describe and record information such as the type, range, and area of the land. Land type patches usually exist in the form of data, including but not limited to: basic information (such as patch ID, area, perimeter), spatial location information (such as patch number, sheet number, geometric shape), land type information (such as land type code, land type name), etc.

[0055] However, since different county-level terminals may use different data formats, coordinate systems, or data standards to collect and store land type patches, the diversity of land type patches may cause difficulties in data integration and analysis, and even data incompatibility may occur. Therefore, preprocessing is performed based on each land type patch to obtain multiple target land type patches. Among them, the preprocessing is used to standardize the data uploaded by different county-level terminals. There are various implementation methods for the preprocessing, which are not limited in the embodiments of the present application. In one feasible implementation, classification and division are performed based on multiple land type patches to obtain the patch type corresponding to each land type patch; according to the patch type, multiple land type patches are sent to the corresponding computing resources under the distributed architecture, where the land type patches corresponding to the same patch type are sent to the same computing resource; obtain the preprocessing process corresponding to each patch type, and control the computing resources to perform preprocessing on each land type patch according to the preprocessing process to obtain multiple target land type patches.

[0056] Step S102: Draw a base map based on multiple target land type patches to obtain a land type patch map, where the land type patch map graphically displays the multi-dimensional information corresponding to the distribution, range, shape, and quantity of the land type patches.

[0057] For the embodiments 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 drawing basis. The base map can be a topographic map, an administrative division map, etc. Then, according to the characteristics of the base map and the display requirements of the target land type patches, parameters such as the drawing scale, legend, and color scheme are set to ensure the clarity and readability of the base map drawing. Next, the pre-processed multiple target land type patches are imported into the drawing software as drawing data, and the drawing tools in the drawing software are controlled to draw the boundaries and filling colors of each target land type patch according to the multiple target land type patches, ensuring that the boundaries of the patches are consistent with the original data and the filling colors can clearly distinguish different land types, so as to obtain the land type patch map. Of course, necessary attribute information can also be added to the land type patch map, such as land type codes, land type names, areas, etc. These attribute information can be displayed in the forms of text annotations, legend explanations, or data tables. The land type patch map is an important basic data for land use planning and management. By drawing the land type patch map, information such as the distribution, scope, shape, and quantity of different land types can be clearly displayed, providing intuitive and accurate data support for fields such as land use planning, land management, and environmental monitoring.

[0058] Step S103: Control the drone to conduct aerial photography detection on the monitoring area corresponding to the land type patch map, obtain the remotely sensed image transmitted back by the drone, and conduct land use analysis based on the remotely sensed image to determine the land use current situation map.

[0059] For the embodiments 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 on the monitoring area to obtain the current land use situation at the monitoring area corresponding to the land type patch map. Accurately judging the land type and current situation helps to optimize the land use structure, improve land efficiency, and achieve the sustainable use of land resources.

[0060] Specifically, based on the land type patch map, clarify the area range to be monitored, including information such as geographical coordinates and area. Then, select a UAV model suitable for the aerial photography task according to the monitored area, ensuring that its flight stability, endurance, payload capacity, etc. meet the requirements, and configure remote sensing equipment such as high-resolution cameras and infrared imaging systems for the UAV to obtain high-quality remote sensing images. Furthermore, according to factors such as the topography and climate conditions of the monitored area, formulate a detailed flight plan, which includes but is not limited to: flight route, flight altitude, flight speed, shooting parameters, etc., to ensure the coverage rate and clarity of the aerial photography images. Furthermore, control the UAV to conduct aerial photography detection on the monitored area corresponding to the land type patch map according to the flight plan. During the flight, remote sensing equipment such as the high-resolution camera carried by the UAV will capture the remote sensing images of the monitored area in real time and transmit the captured remote sensing image data to the electronic device in real time. Then, after obtaining the remote sensing images transmitted back by the UAV, preprocess the received remote sensing image data, including image enhancement, denoising, correction and other processing steps, to improve the clarity and accuracy of the remote sensing images and provide a basis for subsequent land use analysis work. After that, use remote sensing image classification technology to classify the land use types in the monitored area, where the land use types include but are not limited to: cultivated land, forest land, grassland, construction land and other categories. Then, conduct multi-dimensional land use analysis based on the classified remote sensing images to determine the land use analysis results. The multi-dimensional land use analysis can be carried out from multiple aspects such as the quantity, distribution, and structure of land use. Finally, according to the land use analysis results, produce a land use status map, in which the distribution and scope of different land use types and the current characteristics of land use are clearly shown.

[0061] Step S104: Obtain land rights confirmation information, conduct ownership confirmation based on the land type patch map and the land rights confirmation information, and obtain the land ownership confirmation result.

[0062] For the embodiments of this application, the land rights confirmation information is an important basis for confirming land ownership, including but not limited to: land ownership certificates, land contract documents, land registers, etc. Then, digital processing is performed on the land confirmation information to extract key information from documents such as land ownership certificates and land contract documents. For example, land location, area, owner, etc. Furthermore, vectorization processing is performed on the land use patch map using GIS software to extract information such as the boundaries and areas of the patches, and the vectorized land use patch map is superimposed with the key information extracted from the land confirmation information, and the superimposed data is matched in terms of both location and area. When the land use patch and the land rights confirmation information are consistent in both location and area, it indicates that the ownership of the land has been confirmed and is marked as confirmed; when the land use patch and the land rights confirmation information are inconsistent in both location and area, it indicates that there is an abnormality in the ownership of the land and is marked as unconfirmed. Finally, based on the ownership confirmation situation of each piece of land, the land rights confirmation result is obtained.

[0063] Step S105: Perform map fusion based on the land use patch map, the current land use map, and the land rights confirmation result to obtain a panoramic map of land and resources.

[0064] For the embodiments of this application, the data coordinates of the land use patch map, the current land use map, and the land rights confirmation result are unified into the same coordinate system, such as WGS84, CGCS2000, etc., and the data format is converted into a format suitable for map fusion and processing, such as Shapefile, GeoJSON, etc. Furthermore, the land use patch map, the current land use map, and the land rights confirmation result are superimposed as different layers, and according to the visualization requirements of the panoramic map, different colors, symbols, annotations, etc. are used to visually express the fused map, so as to better display the information of the panoramic map of land and resources. The panoramic map of land and resources using multi-layer superposition is used to intuitively display the spatial distribution, form, and mutual relationship of land and resources, which is convenient for quickly understanding and analyzing data and improves the readability and usability of the data.

[0065] It can be seen that in the embodiments of the present application, the land type patches corresponding to the target ranges uploaded by each county-level terminal are obtained, and preprocessing is performed based on each land type patch to obtain a plurality of target land type patches, where the preprocessing is used to normalize the data uploaded by different county-level terminals. Then, based on the plurality of target land type patches, a base map is drawn to obtain a land type patch map, which can clearly display information such as the distribution, range, shape, and quantity of different land types, providing intuitive and accurate data support for fields such as land use planning, land management, and environmental monitoring. Then, the drone is controlled to conduct aerial detection on the monitoring area corresponding to the land type patch map, and land use analysis is performed based on the remote sensing images transmitted back by the drone to determine the current land use map; at the same time, ownership confirmation is performed based on the land type patch map and land rights confirmation information to obtain the land ownership confirmation result. Finally, map fusion is performed based on the land type patch map, the current land use map, and the land ownership confirmation result to obtain a panoramic map of land resources. The panoramic map of land resources using multi-layer superposition is used to intuitively display the spatial distribution, shape, and mutual relationship of land resources, facilitating the quick understanding and analysis of data and improving the readability and usability of the data.

[0066] Further, in order to ensure that the information in the panoramic map is always consistent with the actual situation, in the embodiments of the present application, after map fusion is performed based on the land type patch map, the current land use map, and the land ownership confirmation result to obtain a panoramic map of land resources, it further includes:

[0067] When an update instruction carrying resource update information is detected, update target analysis is performed based on the resource update information to determine the update object, where the update object is at least one of the land type patch map, the current land use map, and the land ownership confirmation result;

[0068] The update object is dynamically updated based on the resource update information to obtain an adjusted update object, and the panoramic map of land resources is dynamically updated based on the adjusted update object to obtain an adjusted panoramic map of land resources.

[0069] For the embodiments of the present application, the panoramic map of land resources is an important tool for reflecting the current situation, ownership, and classification of land resource utilization, and 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 for changes in land resource information. For example, changes in the current land use situation, land transfer, expropriation, circulation, etc. Therefore, the dynamic update technology is introduced to timely adjust the panoramic map of land resources according to the change requirements of land resources to ensure that the information in the panoramic map is always consistent with the actual situation, providing reliable data support for land resource management, urban planning, agricultural development, and ecological environment protection.

[0070] Specifically, the electronic device continuously monitors whether it has received an update instruction carrying resource update information. When it detects an update instruction carrying resource update information, it parses based on the resource update information to determine the update key information corresponding to the resource update. Among them, the update key information includes, but is not limited to: update type, update scope, and update content. And based on the update key information in the resource update information, it performs item-by-item screening and positioning with the update object to determine the update object, where the update object is at least one of the land type patch map, the current land use map, and the land ownership confirmation result. Furthermore, based on the update content in the resource update information, it dynamically updates the update object to obtain the adjusted update object. This dynamic update process will involve operations such as data replacement, addition, deletion, and modification. To ensure the accuracy and reliability of the adjusted update object, after the dynamic update is completed, data verification and validation are performed on the adjusted update object. Finally, the adjusted update object is integrated with other parts of the national land resource panoramic map, and the integrated data is rendered using a map rendering engine to obtain the adjusted national land resource panoramic map, which always remains consistent with the actual situation and accurately reflects various information such as the current situation of land resource utilization, ownership, and classification.

[0071] 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, 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 national land resource panoramic map is dynamically updated to obtain the adjusted national land resource panoramic map. By introducing the dynamic update technology, the national land resource panoramic map is adjusted in a timely manner according to the change requirements of national land resources, ensuring that the information in the panoramic map always remains consistent with the actual situation, and providing reliable data support for national land resource management, urban planning, agricultural development, and ecological environment protection.

[0072] Furthermore, to ensure the sustainable utilization of land resources and quickly and accurately identify the changed land resources, in the embodiment of the present application, after obtaining the national land resource panoramic map by fusing the land type patch map, the current land use map, and the land ownership confirmation result, it further includes:

[0073] Obtain the historical national land resource panoramic map, and based on the national land resource panoramic map and the historical national land resource panoramic map, perform difference screening to determine the different land resources;

[0074] Based on the historical resource information and the current resource information corresponding to the different land resources, perform compliance analysis to determine the resource compliance analysis result;

[0075] When the result of the resource compliance analysis is non-compliant, the discrepant land resources are marked on the national land panoramic map to visually display the distribution of the non-compliant land resources.

[0076] For the embodiments of the present application, the land resource information is a dynamically changing process and is affected by various factors such as nature, economy, and equipment. However, during the use of land resources, there may be cases of illegal occupation and abuse of land resources. 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 a compliance analysis on the discrepant land resources, visually mark the non-compliant land resources, and promote the rational use and protection of land resources.

[0077] Specifically, the historical national land panoramic map is pre-stored in the electronic device. The historical national land panoramic map is the national land panoramic map generated by the previous land survey. Then, the current national land panoramic map and the historical national land panoramic map are registered to ensure their spatial consistency, that is, by selecting the same geographical feature points for registration to improve the registration accuracy. Furthermore, a difference detection is performed on the two registered national land panoramic maps, and the parts of the land resources that are different between the two are marked as discrepant land resources. The compliance standard is obtained. The compliance standard is the judgment standard for land resource compliance formulated based on various factors such as national laws and regulations, local policies, and land use plans. Then, the current resource information of the discrepant land resources is matched with the compliance standard to determine the result of the resource compliance analysis. That is, if the current resource information matches the compliance standard successfully, the result of the resource compliance analysis is determined to be compliant; if the current resource information fails to match the compliance standard, the result of the resource compliance analysis is determined to be non-compliant. When the result of the resource compliance analysis is non-compliant, it indicates that there is a situation of illegal occupation or abuse of the discrepant land resources. Therefore, the discrepant land resources are marked on the national land panoramic map to visually display the distribution of the non-compliant land resources. Marking the abnormal discrepant land resources helps the regulatory authorities quickly understand the current situation and problems of land resource management, and thus take corresponding measures for rectification and improvement to promote the rational use and protection of land resources.

[0078] It can be seen that in the embodiments of the present application, in order to ensure the sustainable utilization of land resources, protect the ecological environment and arable land resources, and quickly and accurately identify the changed land resources, differential screening is performed based on the panoramic map of land resources and the historical panoramic map of land resources to determine the differential land resources. Then, based on the historical resource information and the current resource information corresponding to the differential land resources, compliance analysis is performed to determine the result of resource compliance analysis. When the result of resource compliance analysis is non-compliant, the differential land resources are marked in the panoramic map of land resources to facilitate the intuitive display of the distribution of non-compliant land resources. Performing compliance analysis on the differential land resources and intuitively marking the non-compliant land resources promotes the rational utilization and protection of land resources.

[0079] Furthermore, in order to improve the preprocessing efficiency of land type patches, make full use of the advantages of computing resources, and effectively avoid resource waste, in the embodiments of the present application, preprocessing is performed based on each land type patch to obtain multiple target land type patches, including:

[0080] Performing classification on multiple land type patches to obtain the patch type corresponding to each land type patch;

[0081] According to the patch type, sending multiple land type patches to the corresponding computing resources under the distributed architecture, where the land type patches with the same patch type are sent to the same computing resource;

[0082] Obtaining the preprocessing process corresponding to each patch type, and controlling the computing resources to preprocess each land type patch according to the preprocessing process to obtain multiple target land type patches.

[0083] For the embodiments of the present application, there are multiple patch types corresponding to land type patches, including but not limited to: regular patches, long and narrow patches, small patches, etc. Therefore, when preprocessing multiple land type patches, classification is preferentially performed on multiple land type patches to obtain the patch type corresponding to each land type patch. The specific implementation process of the classification is as follows: Graphically display the land type patches in the form of data to obtain graphical land type patches. Then, using image processing technology, extract the shape features and texture features of each land type patch. 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, perform patch type analysis according to the extracted shape features and texture features to determine the patch type, that is, for the land type patches with regular shape features, determine the patch type as regular patches, for example, land type patches with smooth boundaries and shapes close to rectangles or circles; for the aspect ratio in the shape features, identify the land type patches with a length much greater than the width and determine the patch type as long and narrow patches; for the area value in the shape features, identify the land type patches with an area smaller than the area threshold and determine the patch type as small patches.

[0084] In order to improve the preprocessing efficiency of land type patches, make full use of the advantages of computing resources, and effectively avoid resource waste, in the embodiments of the present application, computing resources are deployed in a distributed architecture manner, and multiple land type patches are sent to the corresponding computing resources under the distributed architecture according to the patch types to achieve parallel computing and batch processing of preprocessing. Since the characteristics of land type patches of different patch types are different, the preprocessing operations to be performed will also be different. Therefore, the preprocessing processes corresponding to different patch types are pre-stored in the electronic device, and the preprocessing process corresponding to the patch type can ensure that the target land type patches after preprocessing meet the requirements of subsequent base map drawing. Thus, the preprocessing process corresponding to each patch type is obtained, and the computing resources are controlled to preprocess each land type patch according to the preprocessing process to obtain multiple target land type patches. Different preprocessing processes are adopted for different types of land type patches, which improves the accuracy of preprocessing and the consistency of the formats of target land type patches.

[0085] It can be seen that in the embodiments of the present application, in order to improve the preprocessing efficiency of land type patches, make full use of the advantages of computing resources, and effectively avoid resource waste, classification and division are performed based on multiple land type patches to obtain the patch type corresponding to each land type patch. Then, according to the patch type, multiple land type patches are sent to the corresponding computing resources under the distributed architecture, where the land type patches corresponding to the same patch type are sent to the same computing resource. Furthermore, the preprocessing process corresponding to each patch type is obtained, and the computing resources are controlled to preprocess each land type patch according to the preprocessing process to obtain multiple target land type patches.

[0086] Furthermore, in order to enable the national land panoramic map to provide richer spatial information and more intuitive visual effects, in the embodiments of the present application, map fusion is performed based on the land type patch map, the current land use map, and the land ownership confirmation result to obtain the national land panoramic map, including:

[0087] Using geographic information system technology, the land type patch map, the current land use map, and the land ownership confirmation result are fused to generate a preliminary panoramic map;

[0088] Terrain data and building data are obtained, and 3D modeling is performed based on the terrain data and building data to obtain a terrain model and a building model;

[0089] Based on the preliminary panoramic map, the terrain model, and the building model, visual fusion is performed to obtain the national land panoramic map.

[0090] For the embodiments of this application, in order to more truly reflect the spatial distribution and morphological characteristics of land and resources and achieve an all-round and multi-angle display of land and resources, through map fusion and 3D modeling technologies, scattered land type patch maps, current land use maps, land ownership confirmation results, as well as terrain and building data are integrated into a panoramic land and resources map. Through visual fusion, the panoramic land and resources map can provide richer spatial information and more intuitive visual effects, which helps to discover the utilization potential and problems of land resources.

[0091] Specifically, using geographic information system technology, the land type patch map, current land use map, and land ownership confirmation results are overlaid as different layers to ensure the correct correspondence of the spatial relationships between the layers. Then, according to the spatial position relationship, the attribute data of each layer are associated to ensure that each geographical entity has complete attribute information in the fused map, and a preliminary panoramic map is generated based on the fused map data. The preliminary panoramic map includes the geographical entities and attribute information of all layers to present a clear and accurate visual effect. Furthermore, terrain data and building data are obtained. The terrain data include, but are not limited to: elevation data, geographical texture data, etc.; the building data include, but are not limited to: information such as the geometric shape, size, position, and texture of the building. Then, 3D modeling software is used to construct 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, 3D modeling software is used to construct a building model, that is, the building shape is built according to the geometric shape of the building, and building texture data is applied to refine and optimize the building. Furthermore, the terrain model and the building model are integrated into a scene, and the position, size, and orientation of the models 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 for details, such as adding shadows and adjusting lighting effects, to enhance the three-dimensional sense of the building. Then, the terrain model with the embedded building model is fused with the preliminary panoramic map. The texture information of the panoramic map is applied to the terrain model through texture mapping, and the scaling, rotation, and position of the texture are adjusted to ensure that the texture matches the geometric shape of the terrain model. Finally, a panoramic land and resources map is obtained. This panoramic land and resources map more intuitively displays the spatial distribution and morphological characteristics of land resources, which helps to discover the utilization potential and problems of land resources. Of course, an interactive design can also be introduced to allow users to freely explore the panoramic land and resources map through operations such as zooming, rotating, and panning, enhancing the user experience.

[0092] It can be seen that in the embodiments of the present application, by using geographic information system technology, the land type patch map, the current land use map, and the land ownership confirmation results are map - fused to generate a preliminary panoramic map. Then, 3D modeling is performed based on terrain data and building data to obtain a terrain model and a building model. Finally, 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 3D modeling technologies, the scattered land type patch maps, current land use maps, land ownership confirmation results, as well as 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 helps to discover the utilization potential and problems of land resources.

[0093] Furthermore, in order to enhance the vividness and authenticity of the display of land and resources and facilitate land and resources management personnel to more intuitively understand the utilization situation and potential of land resources, in the embodiments of the present application, after 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, the following steps are also included:

[0094] The panoramic map of land and resources is imported into the VR platform to obtain a VR model, so that land and resources management personnel can enter the three - dimensional land space by wearing VR devices;

[0095] VR scene feedback information is obtained, and the VR model is optimized and adjusted based on the VR scene feedback information to obtain an optimized VR model.

[0096] For the embodiments of the present application, when the panoramic map of land and resources is imported into the VR platform, according to the requirements of the VR platform, processing such as format conversion and size adjustment is performed on the panoramic map of land and resources, 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 scenes in the panoramic map of land and resources, including but not limited to terrains, landforms, buildings and other scenes. Of course, interactive functions such as hot - spot marking and information query can also be added to the VR model to facilitate immersive experience for land and resources management personnel. Furthermore, land and resources management personnel wear VR devices and 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 device. Through VR technology, an immersive experience method is provided for land and resources management personnel, enhancing the vividness and authenticity of the display of land and resources and facilitating land and resources management personnel to more intuitively understand the utilization situation and potential of land resources.

[0097] Then, collect the VR scene feedback information of land and resources management personnel in the VR scene. The feedback information includes, but is not limited to: the authenticity of the model, the convenience of the interaction function, the optimization suggestions for the scene, etc. Furthermore, based on the VR scene feedback information, optimize and adjust the VR model to obtain an optimized VR model. Among them, the dimensions of the optimization and adjustment include, but are not limited to: performing refined processing on the terrain, landform, buildings, etc. in the model to improve the authenticity of the model; improving and optimizing the interaction function to improve the operation convenience of management personnel. Provide the optimized VR model to land and resources management personnel for experience again, collect new feedback information, and conduct a new round of optimization and adjustment. Through the way of cyclic iteration, continuously improve the VR model until it meets the needs of land and resources management.

[0098] It can be seen that in the embodiment of the present application, the panoramic map of land and resources is imported into the VR platform to obtain a VR model, so that land and resources management personnel can enter the three-dimensional land space by wearing VR devices. Then, obtain the VR scene feedback information, and optimize and adjust the VR model based on the VR scene feedback information to obtain an optimized VR model. Through VR technology, an immersive experience method is provided for land and resources management personnel, improving the vividness and authenticity of land and resources display, and facilitating land and resources management personnel to more intuitively understand the utilization situation and potential of land resources.
