Description

Technical Field

[0001] This invention relates to the field of land resource management technology, and in particular to a method and apparatus for managing changes in land resources. Background Technology

[0002] Land use change surveys are fundamental to understanding changes in land use status and maintaining the accuracy and timeliness of land survey data. In terms of technological applications, 3S technologies have become important tools for land use change surveys. Specifically, RS (Remote Sensing) technology is used to detect changed land parcels, GPS (Global Positioning System) is used for mapping changed land parcels, and GIS (Geographic Information System) is used for database updates and management. Furthermore, systems such as the MAPSUV digital mapping system attempt to address the issue of map-attribute integration in cadastral data updates, but most systems still have shortcomings in the synchronous updating, real-time performance, and intelligence of graphic and attribute data.

[0003] In related technologies, the existing land change survey technology has the problem of "separation of map and attribute", which is manifested in the following ways: (1) At the data model level, most mainstream land management information systems are developed based on traditional CAD platforms or early GIS technology architectures. Their underlying data models physically separate spatial graphic data (such as parcel boundary lines) from attribute data (such as rights holder information, land area, etc.). Graphic data is usually stored in a specific format file, while attribute data depends on relational database tables. The two are only logically associated through keywords (such as parcel number); (2) At the business process level, when updating data, operators must frequently switch between graphic editing software and attribute management software to adjust graphics and enter attributes respectively. The operation process is complicated, which not only leads to extremely low work efficiency, but also easily causes serious consequences of data inconsistency. For example, the graphics have been changed but the attributes have not been updated synchronously, or the attributes have been corrected but the graphics have not been adjusted accordingly, resulting in the phenomenon of "two separate skins of map and attribute"; At the data application level, this separation architecture reduces the efficiency of association query, seriously hinders the ability to conduct in-depth data mining and auxiliary decision-making based on "one map", and greatly reduces the intelligence and reliability of the system. Summary of the Invention

[0004] This invention provides a land resource change management method and apparatus to solve the problems of existing technologies that physically isolate spatial graphic data from attribute data, requiring operators to frequently switch between graphic editing software and attribute management software, resulting in complex operation processes, high error rates, reduced efficiency of correlation queries, and compromised system intelligence and reliability.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] The following is combined Figures 1-3 The present invention describes a land resource change management method and apparatus.

[0023] Figure 1 This is one of the flowcharts illustrating the land resource change management method provided by the present invention, such as... Figure 1 As shown, the method includes the following steps: Step 110: Periodically collect change information of each land unit object in the target area and generate change event data. Each land unit object includes spatial graphic information, plot attribute information and management status information.

[0024] In this step, the periodicity can be set according to the actual needs of land management. For example, in order to change the problem of the traditional annual change being lagging behind, it can be set to be monitored in real time, daily, weekly or monthly at high frequency.

[0025] In this step, the target area can be a specific geographic area within the user's jurisdiction (such as a special land protection zone, an administrative jurisdiction, etc.).

[0026] In this step, the land unit object serves as the data carrier for various plots of resources within the target area, including spatial graphic information, plot attribute information, and management status information. Among them, the spatial graphic information includes the boundary coordinate sequence of the plot (such as the coordinates of the vertex of a polygon), the plot attribute information includes text data such as plot number, right holder, use, and area, and the management status information includes the current business status of the plot (such as "certificate issued", "proposed expropriation", "normal", etc.).

[0027] In this step, the change information can be clues about changes in the physical form of the land parcel or changes in business ownership perceived through different channels. These scattered clues are encapsulated into data packets to generate change event data.

[0028] For example, this embodiment integrates multiple data acquisition methods to construct a routine monitoring network that coordinates air and ground operations: ① Data internal verification: Establish inspection rules for graphic overlap, attribute correctness, and ownership conflicts, and regularly verify graphic data. The built-in verification engine automatically detects data quality issues and generates data packages to be verified.

[0029] ② Field inspection and reporting: Inspectors take photos, locate and report any changes in the land they find on site, and the system automatically generates verification tasks.

[0030] ③ Business system event triggering: It connects with business systems such as project management and engineering management. When key business events such as land acquisition or replacement occur, a pre-change notification is automatically generated to indicate that the relevant land plots will soon be changed.

[0031] In this embodiment, the perceived change information is further encapsulated into change event data and stored in the event database for processing. The change event data may include information such as event ID, discovery time, geographical location, change type (suspected), and data source.

[0032] In this embodiment, different land unit objects in the target area correspond to different unique identifiers; change event data includes event number, event discovery time, location information, change type, and data source.

[0033] In this embodiment, a land data model can be designed to achieve integrated management of graphic data and attribute data. This model uses a unified identifier to associate graphics and attributes, supports bidirectional synchronous updates, and completely solves the problem of map-attribute separation in traditional land change management.

[0034] Specifically, in order to achieve integrated management of map and attribute, this embodiment first creates a land unit object for each piece of land at the data layer. This object is a unified carrier of graphics and attributes. Each land unit object is assigned a globally unique identifier (GUID), which remains unchanged throughout its entire lifecycle.

[0035] In a specific implementation scenario, the land management department conducts routine monitoring of "Area A" (target area) within its jurisdiction. Each independent plot within this area is stored in the database as a "land unit object," possessing a unique GUID identifier and bound to a precise red line boundary (graphic), the user "Unit A" (attribute), and the status "normal use" (status). This embodiment is configured to perform a multi-source data scan "weekly." Every weekend, the system automatically runs data quality inspection rules, comparing the graphics with attribute logic. In addition, inspectors regularly conduct field surveys and verifications in the area, discovering that Unit A has privately expanded its fence, occupying part of the vacant land. The inspectors sketch the approximate area on-site and upload it. Simultaneously, the system receives a notification from the engineering management department via an interface, indicating that the plot is applying for a renovation and expansion project. This embodiment combines the expansion clues discovered by the above-mentioned field inspections with the renovation and expansion notifications from the business system to generate a standard change event data, marked as "field inspection + business collaboration," located in the Unit A plot in Area A, and the suspected change type is "graphical range change."

[0036] Step 120: Determine the target land unit object based on the change event data, and process the target land unit object according to the preset rule engine to obtain a new target land unit object; the preset rule engine supports at least one of the following: spatial graphic change-driven attribute update rules, plot attribute change constraint graphic rules, and incremental spatiotemporal version management rules.

[0037] In this step, the spatial location or index number in the change event can be used to locate the unique land parcel to be changed in the database (i.e., using GUID for positioning), which is the target land unit object.

[0038] In this step, a processing task is first created for each change event data, and then processed according to predefined business rules as follows: (1) By matching spatial location, the change event data is associated and bound with the corresponding target land unit object.

[0039] (2) The preset rule engine has a variety of business rules pre-defined. When an operation is performed on a land parcel object, the rule engine automatically triggers the corresponding linkage logic: ① Graphical Change-Driven Attribute Update Rules: When a land parcel object is graphically divided, the system automatically creates new sub-parcel objects and forces the operator to assign or confirm attributes inherited from the original parent parcel for the new sub-parcels (e.g., dividing from the original right holder A into right holders A and B), and automatically recalculates the area. When graphical merging is performed, the system automatically merges attributes or prompts for handling attribute conflicts.

[0040] ② Attribute change constraint graphical rules: When the land use nature and other attributes of a plot are modified, the rule engine will automatically check whether the new nature meets the constraints such as the planning control line of the space where the plot is located. If it does not meet the constraints, a warning will be issued and the plot will be prohibited from being added to the database.

[0041] ③ Spatiotemporal version management: Each successful change operation will not overwrite the old data; the system adopts incremental version management, creating a new data version (Version N+1) for each update, and storing the old version (Version N) in the historical database. Each version records metadata such as timestamp, operator, reason for change, and snapshots of the state before and after, thus forming a complete and traceable version chain of the land parcel object lifecycle.

[0042] For example, after receiving change event data, the operator first retrieves the original land parcel object (version V1) of Unit A through the system based on location information (event coordinates). Then, based on the survey data returned from the inspection, the operator performs a division operation on the land parcel graphic of Unit A (separating the expansion part). At this time, the graphic change-driven attribute update rule is triggered, the geometric area of ​​the two new land parcels after division is calculated, and an attribute entry box is forcibly popped up, requiring the operator to confirm whether the right holder of the newly divided land parcel remains "Unit A" or is changed to "new entity", preventing the data inconsistency problem of the graphic changing but the area and ownership attribute remaining unchanged. Suppose the operator changes the attribute of the newly divided land parcel to commercial land, at this time the rule engine triggers the attribute change constraint graphic rule, detects that the spatial planning of the area belongs to a strictly industrial control zone, the system immediately reports an error and prevents the graphic change from being entered into the database until the attribute is corrected to conform to the planning type. After the processing is completed, the system does not directly modify the V1 object in the database, but generates two new land parcel objects (versions V2-A and V2-B), marks the V1 object as a historical state, records the change time as the current time, and the change reason as expansion division.

[0043] Step 130: Review the new target land unit objects and publish the data service for the new target land unit objects that have passed the review.

[0044] In this step, administrators with relevant security permissions can perform quality checks on new target land units, such as by comparing graphics and attributes side-by-side or by overlaying historical versions with the current version.

[0045] In this step, after the review is approved, the new version of the data can be officially marked as updated, and the GIS map service interface can be updated in real time and pushed synchronously to related business systems (such as planning systems and real estate registration systems) to ensure that all departments are using the same set of the latest data.

[0046] Specifically, in this embodiment, the differences in graphics and attributes before and after the change can be compared between the target land unit object and the new target land unit object. After the review is approved, the new version of the data will officially take effect and become the current status of the system, that is, the new target land unit object will be used as the current target land unit object. The system will then automatically update the relevant map services and issue data update notifications to other related business systems to ensure that all applications operate based on the latest and consistent data.

[0047] For example, an auditor opens the system task list and views the land parcel change application from Unit A. The left side of the system interface displays the V1 version before the change, and the right side displays the V2 version after the change. After confirming the accuracy of the division location, the correctness of the area calculation, and compliance with planning requirements by checking the highlighted differences, the auditor clicks "Approval." Service publishing includes status updates, map updates, and message pushes. Status updates refer to the V1 object in the database being officially archived as history, and the V2 object becoming the current valid data. Map updates refer to the automatic refresh of the map service on the land "one map" portal website, allowing jurisdiction managers to see the latest land parcel division form by refreshing their browsers. Message pushes refer to the system automatically sending a message to the real estate registration department's business system: "The land parcel with GUID XXXX has completed the division change. Please update the registration information synchronously," achieving cross-departmental data collaboration.

[0048] The land resource change management method provided in this invention improves the efficiency of land change monitoring by periodically collecting change information of each land unit object in the target area and generating change event data. Then, the target land unit object is determined based on the change event data, and the target land unit object is processed according to a preset rule engine to obtain a new target land unit object. This method improves the automation of the process by linking the land parcel object model and the rule engine, and publishes the data service of the new target land unit object that has passed the review. This improves the efficiency of related queries and the intelligence and reliability of the system.

[0049] In some embodiments, after publishing the data service for the new target land unit object that has passed the review, the land resource change management method further includes: obtaining the change information of the target land unit object's content in a first time period through a time slider mechanism, and generating a lifecycle report file; the first time period is a set of any time points before the current time point.

[0050] In this embodiment, the time slider mechanism is connected to the spatiotemporal version data model in the backend database, allowing users to dynamically filter and display historical version data stored in the database by dragging the slider or entering a time range.

[0051] In this embodiment, the first time period includes the historical observation window period that the user is interested in. It can be the entire life cycle of the land parcel from its initial generation to the present, or it can be a specific few years (such as 2020 to 2025).

[0052] In this embodiment, the change information can be retrieved and linked together based on the user-selected time period, which includes all approved valid versions (Version N, N+1...) of the land parcel object within that time period.

[0053] In this embodiment, the lifecycle report file can be a comprehensive document generated based on the retrieved version chain, containing text descriptions, graphical snapshot evolution, and attribute change records, which is equivalent to a digital archive of the land parcel.

[0054] Specifically, users can use the time slider tool to go back to any historical point in time, view the spatial distribution and attribute status of the land parcels at that time, and generate a life course report for a single land parcel, clearly showing all the historical events it has experienced, such as division, merger, and attribute changes, providing an immutable chain of data evidence for the mediation of ownership disputes, policy benefit assessment, and research on the evolution of national land space.

[0055] The land resource change management method provided in this invention obtains the change information of the target land unit object in the first time period through a time slider mechanism and generates a life cycle report file. It makes full use of the data assets accumulated by incremental spatiotemporal version management and solves the problem of historical traceability caused by overlay updates in the prior art through intuitive time slider and automated report generation.

[0056] In some embodiments, the land resource change management method further includes: sending change information of the target land unit object to the target blockchain over multiple time periods, wherein the change information includes at least one of change event data, new target land unit objects, and new target land unit objects that have passed the review; reading and tracing the change information of the target land unit object's content in the first time period based on the target blockchain, and generating a lifecycle report file; wherein the first time period is a set of any time points before the current time point.

[0057] In this embodiment, blockchain technology is introduced into land change management and used for the storage and traceability of change records. This embodiment utilizes the immutability and traceability of blockchain to record the entire process information of each land change, including data before and after the change, change time, responsible person, etc., forming a reliable change chain.

[0058] In this embodiment, the target blockchain can be a consortium blockchain or a private blockchain jointly maintained by the land management department and departments such as auditing, judiciary, and real estate registration, and has the characteristics of decentralization, immutability, and full traceability.

[0059] In this embodiment, the change information includes not only the final result, but also change event data (trigger source) and review process data, ensuring dual evidence of process and result. At key nodes in the completion of land change business (such as the moment the review is approved), the system automatically packages the core change data into a blockchain transaction and stores it on the blockchain to form a digital fingerprint, thus completing the on-chain storage of change information.

[0060] In this embodiment, when generating a report, the system no longer relies solely on the local database, but directly queries the distributed ledger on the blockchain, or uses the hash value on the chain to verify the authenticity of the local data, thereby generating a lifecycle report file with legal effect.

[0061] The land resource change management method provided in this invention sends the change information of the target land unit object to the target blockchain at multiple time periods, and reads and traces the change information of the target land unit object in the first time period based on the target blockchain. This greatly enhances the credibility and security of land change data and prevents data tampering. It is particularly suitable for scenarios with high data reliability requirements, such as land ownership changes. At the same time, the decentralized nature of blockchain is conducive to data sharing and collaborative updates among multiple departments, forming a hybrid model of subject management + blockchain notarization, which ensures both efficiency and enhanced credibility.

[0062] In some embodiments, the data service release of a new target land unit object that has passed the review includes: using a cloud-native architecture-based collaborative update mechanism to share and synchronize change information of the target land unit object over multiple time periods among different users; the change information includes at least one of change event data, a new target land unit object, and a new target land unit object that has passed the review.

[0063] In this embodiment, the system can be deployed on a government cloud or private cloud environment. The distributed system built with microservices and containerization technology has the characteristics of high concurrency, elastic scaling and continuous delivery.

[0064] In this embodiment, the collaborative update mechanism establishes a unified workspace for real-time online operation across multiple levels and departments (such as land, planning, and law enforcement). When data changes submitted by any terminal (such as a field tablet or an office server) are approved in the cloud, the system uses message queues or WebSocket technology to push the change information to all clients that have subscribed to the service in that area in real time, achieving millisecond-level data consistency. This connects the transmission of offline data packets between different levels of areas in traditional land management, enabling efficient data sharing and synchronization.

[0065] Specifically, this embodiment adopts a completely cloud-native architecture to cloudify all functions of land change management, and uses a microservice architecture to decouple and independently expand functional modules; users from different departments and levels can collaboratively update data through a unified cloud platform to achieve real-time data sharing and synchronization.

[0066] For example, in land management scenarios involving cross-departmental and cross-level collaboration, the system is deployed on an agency platform. After internal staff approve the subdivision and modification of a plot of land belonging to Unit A, the data is submitted via a dedicated network. The message distribution microservice in the cloud-native architecture immediately captures this data change, identifies the land plot involving various levels of land management user groups, and performs the following multi-device synchronization: (1) The land use status map of the jurisdiction displayed on the large screen in the center of the agency does not need to be manually refreshed. It automatically receives the change increment packet through WebSocket connection. The plot of land of Unit A instantly changes from one plot to two plots, and the idle land area index in the statistical chart jumps and updates accordingly.

[0067] (2) When the field law enforcement personnel receive the push notification, the map cache is automatically updated; when he passes by Unit A, the terminal map displays the new red line after the division, thus avoiding misjudgment of his illegal construction due to data lag.

[0068] (3) The land management unit change system subscribed to the change through the cloud API (Application Programming Interface) and automatically updated the status of the newly divided land parcel from "already transferred" to "awaiting investment", thus achieving seamless connection of business flow.

[0069] The land resource change management method provided in this invention, through the good scalability and elasticity of cloud-native architecture, can dynamically adjust resource allocation according to business needs, which facilitates function updates and module reuse. At the same time, the multi-user collaborative working mode is conducive to improving data update efficiency and quality control, and is suitable for areas with good conditions and good network coverage, as well as scenarios of multi-department collaborative operations, forming a "cloud-edge-device" collaborative architecture that balances the efficiency of centralized processing and the real-time performance of edge computing.

[0070] Figure 2 This is the second flowchart of the land resource change management method provided by the present invention. Figure 2 In the illustrated embodiment, the land resource change management method further includes the following steps: S101 constructing a land parcel object model integrating map and ownership; S102 routinely sensing land parcel changes using multi-source data; S103 map-owner linkage update processing based on a rule engine; S104 change review and data service release; S105 full lifecycle tracing and spatiotemporal analysis. In S103, the updated data can be used as the comparison benchmark for the original land unit object, and change verification tasks or events can be generated, thereby driving the preset rule engine to perform corresponding processing.

[0071] The land resource change management device provided by the present invention is described below. The land resource change management device described below and the land resource change management method described above can be referred to in correspondence.
