[0002] A land parcel refers to a plot of land or space enclosed by a property boundary line. It is a piece of land with a definite boundary and definite property rights. A land parcel is the basic unit of cadastral land. Property rights registration is a work of unified property rights investigation, unified property rights registration, and unified issuance of real estate and land property rights certificates for rural homesteads, collective construction land, and buildings and structures on the land. During the property rights registration process, if the object of the certificate, i.e. a certain plot of land, does not meet the relevant indicators, the certificate cannot be issued.

[0062] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0063] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0064] Hereinafter, the terms "including", "having" and their cognates, which may be used in various embodiments of the present invention, are intended only to indicate specific features, numbers, steps, operations, elements, components or combinations of the foregoing items, and should not be understood as first excluding the existence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing items or adding the possibility of one or more features, numbers, steps, operations, elements, components or combinations of the foregoing items.

[0065] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0066] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by those skilled in the art to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present invention.

[0067] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0068] See also Figure 1 , Figure 1 This is one of the flow charts of a method for processing land parcel data provided in the embodiment of the present application. This application uses a feature manipulation tool (Feature Manipulate Engine, referred to as FME) to achieve rapid processing of land parcel data and output of results. FME is a spatial data conversion processing system. Figure 1 As shown, the land parcel data processing method mainly includes:

[0069] Step S101, obtain at least one first map spot corresponding to the land parcel to be processed and at least one second map spot corresponding to the land of non-land parcel type, wherein the first map spot and the second map spot are both composed of a plurality of basic units with the same first area value, and the attribute information of each of the first map spots and each of the second map spots includes a preset attribute type, the attribute value corresponding to each attribute type and the coordinate value of each corresponding basic unit.

[0070] A map spot refers to a single land type plot and a single land type plot divided by administrative boundaries, land ownership boundaries or linear features, such as urban land, village land, mining land, etc. The attribute information of a map spot is a type of information used to characterize the specific characteristics of the map spot, including attribute types and attribute values ​​corresponding to each attribute type, for example: area - 10m 2 , land type - forest land, etc. The basic unit is the smallest unit that constitutes the map spot. The specific shape and first area value of the smallest unit can be customized according to specific usage requirements. By counting the number of basic units covered by a certain map spot, the area value corresponding to the map spot can be obtained.

[0071] See also Figure 2 , Figure 2The second flowchart of a method for processing plot data provided in an embodiment of the present application. Due to certain limitations in the accuracy of the data acquisition means or tools, the plot data corresponding to the first image spot and the basic data corresponding to the second image spot may not be directly used for subsequent research and processing. Therefore, it is necessary to pre-process these data, such as geometric precision correction, registration, image mosaicking and cropping.

[0072] The non-plot type of land includes a road or a channel, and the step of obtaining at least one second map spot corresponding to the non-plot type of land includes:

[0073] classifying the road or the channel according to the marking information of the road or the channel;

[0074] Taking the linear road or the channel as the center, expanding to both sides according to the buffer distances corresponding to different types of roads or channels, to obtain at least one buffer strip corresponding to the road or channel;

[0075] Merging all of the buffer strips into a buffer zone;

[0076] The buffer zone is determined as the second map patch corresponding to the road or the channel.

[0077] Road and channel data are generally linear features. In order to understand the situation of land occupying roads and channels, the Bufferer converter in FME can be used to convert linear features into surface features. This converter takes the linear feature as the center line and expands to both sides.

[0078] See also Figure 3 , Figure 3 A schematic diagram of road data classification involved in a land parcel data processing method provided in an embodiment of the present application. In specific implementation, the road data and channel data can be classified first. For example, since different levels of roads correspond to different red line distances, the road data can be divided into national roads, provincial roads, county roads and township roads according to different levels through the Attribute Filter converter. The red line distance generally refers to the boundary line of the planned urban road land. No permanent buildings are allowed to be built within the red line. This red line distance can be defined as a buffer distance. See Figure 4 , Figure 4 A schematic diagram of buffer distance setting involved in a plot data processing method provided in an embodiment of the present application. When setting parameters, different buffer distances are set according to the road grade. Taking the national highway as an example, its road red line is determined by expanding the original width of the road 20 meters on both sides, and the buffer distance parameter set is @Value(WIDTH) / 2+20.

[0079] See also Figure 5 , Figure 5A schematic diagram of the road data preprocessing process involved in a plot data processing method provided in an embodiment of the present application. With the linear road or channel as the center, the buffer distances corresponding to different types of roads or channels are expanded to both sides, and after obtaining at least one buffer strip corresponding to the road or channel, all buffer strips can be merged into a buffer surface by using a Dissolver converter, thereby reducing the amount of data and improving data processing efficiency.

[0080] Step S102: superimpose the first pattern spot and the second pattern spot to obtain overlapping area values ​​corresponding to all the basic units of the overlapping part.

[0081] In order to understand the superposition of the plot data and the basic data, after completing the data preprocessing, the first map spot can be superimposed on the second map spot. Figure 6 , Figure 6 A schematic diagram of overlay processing involved in a method for processing parcel data provided in an embodiment of the present application. In specific implementation, one or more conditions can be set in the Tester converter of FME to select and output the required data. Taking the screening of parcel data that occupies basic farmland as an example, by setting the conditions: type = parcel AND data type = basic farmland, the overlapping area value of the intersection or overlapping part of the first map spot corresponding to the parcel and the second map spot corresponding to the basic farmland is obtained, and the overlapping part inherits the attribute information of the corresponding parts of the two maps.

[0082] The second image spot corresponds to at least two first plots, and the step of superimposing the first image spot and the second image spot comprises:

[0083] Determine whether any two of the first plots are adjacent;

[0084] Merging the adjacent first plots into second plots, and fusing attribute information of all first plots contained in each of the second plots;

[0085] Combining all remaining non-adjacent first plots and all second plots into a target plot;

[0086] The first image spot and the target image spot are superimposed.

[0087] When performing overlay processing, the second plot corresponding to the basic data may be composed of two or more first plots. In order to improve data processing efficiency, the attribute information of adjacent first plots can be fused to obtain the second plot. Figure 7 , Figure 7A fusion diagram of the first plot involved in a plot data processing method provided in an embodiment of the present application. A second plot is composed of six first plots A, B, C, D, E, and F, wherein A and B are adjacent, C and D are adjacent, B and C are not adjacent, and E and F are not adjacent. According to the above processing steps, AB can be fused into the second plot G, and CD can be fused into the second plot H. Since B and C are not adjacent, the corresponding second plots G and H do not need to be further fused. The obtained target plot includes two non-adjacent first plots E and F, and non-adjacent second plots G and H.

[0088] After the first image spot and the second image spot are superimposed to obtain the overlap area value corresponding to the overlapped part, the present application can output two different types of information based on the superimposed processing result. Below, the embodiments of the present application respectively explain these two different types of output information.

[0089] The first category, refer to steps S104-S105. It can be determined whether the land parcel to be processed meets the registration conditions according to the overlapped area value, and the corresponding processing results are output. Specifically:

[0090] Step S104, if the overlapping area value is greater than the first preset threshold and / or the ratio of the overlapping area value to the area value of the first map spot is greater than the second preset threshold, output a processing result indicating that the land parcel to be processed does not meet the registration conditions.

[0091] Step S105, if the overlapping area value is less than or equal to the first preset threshold, and / or the ratio of the overlapping area value to the area value of the first map spot is less than or equal to the second preset threshold, output a processing result indicating that the land parcel to be processed meets the registration conditions.

[0092] "Determining whether the pending land parcels meet the registration conditions based on the overlapping area value" aims to determine which land parcels do not meet the conditions for registration and confirmation of ownership. The specific determination method can generally correspond to the registration regulations of the real estate registration centers of various districts and counties, while combining local policies and land conditions. For example, the area indicators of the land parcels occupying various red lines, the percentage of the area occupied by various red lines to the original land parcel area, etc. can be used to determine whether the pending land parcels meet the registration conditions.

[0093] The present application can output a processing result indicating whether the to-be-processed land parcel meets or does not meet the registration conditions by judging the size relationship between the overlapping area value and the first preset threshold, and / or the size relationship between the ratio of the overlapping area value and the area value of the first map spot and the second preset threshold.

[0094] The land parcel data processing method provided in this application can superimpose the first image spot corresponding to the land parcel with the second image spot corresponding to a certain type of non-land parcel land to further obtain the determination result. In specific implementation, the determination results corresponding to different types of non-land parcel land can be processed by AND or logic to obtain a more accurate determination result. For example, you can first determine:

[0095] 1. Whether the land parcel exceeds the regional jurisdiction;

[0096] 2. Whether the land parcel illegally occupies more than 2 square meters of cultivated land;

[0097] 3. Whether the land parcel occupies an ecological red line area exceeding 2 square meters;

[0098] 4. Whether the land parcel occupies more than 2 square meters of basic farmland;

[0099] 5. Whether the land parcel occupies more than 10% of the cultivated land in the third land survey;

[0100] 6. Whether the land parcel occupies an area of ​​more than 2 square meters along the road red line;

[0101] 7. Whether the land parcel occupies a channel area exceeding 2 square meters;

[0102] 8. Whether there is any partial overlap between the land parcel and the geological disaster data.

[0103] For the above 8 judgment conditions, it can be further set that when the logical results corresponding to N of the judgment conditions are "true", the corresponding land parcel is judged to meet the registration conditions, otherwise it does not meet the registration conditions, where N is a positive integer, 1≤N≤8.

[0104] If the overlap area value is less than or equal to the first preset threshold, and / or the ratio of the overlap area value to the area value of the first pattern spot is less than or equal to the second preset threshold, after the step, the method further includes:

[0105] Obtain data on relocation of migrants;

[0106] Linking the first image spot with the non-local immigrant relocation data to determine whether the first image spot is associated with the non-local immigrant relocation data;

[0107] If the first image spot is associated with the non-local immigrant relocation data, outputting a processing result indicating that the to-be-processed land parcel does not meet the registration conditions;

[0108] If the first map spot is not associated with the relocation data of the immigrants from other places, the output is a processing result indicating that the land parcel to be processed meets the registration conditions.

[0109] In specific implementation, if the overlapping area value is less than or equal to the first preset threshold, and / or the ratio of the overlapping area value to the area value of the first map spot is less than or equal to the second preset threshold, it can only indicate that the occupied area or proportion of the pending land to other non-plot types of land meets the registration conditions, and the pending land meets the preliminary registration conditions. It is also possible to continue to determine whether the pending land that meets the preliminary registration conditions is associated with the relocation data of immigrants from other places. Specifically, if the pending land meets the preliminary registration conditions, but the owner or user of the pending land and other relevant rights holders have moved, that is, "the first map spot is associated with the relocation data of immigrants from other places", then the pending land does not meet the registration conditions.

[0110] When obtaining the data of migrant relocation, since migrant relocation data generally does not have vector data, it can be associated with the first map by data joining. The attributes in the migrant relocation data can be connected to the existing features or attribute information in the first map through the DatabaseJoiner transformer in FME. For example, the first map can be joined with the migrant relocation data through the attribute information of the ID card number, and the associated data can be output.

[0111] In specific implementation, it is also possible to first determine whether the first map spot is associated with the data of immigrant relocation from other places, and if not, then make a related judgment on the overlap area value or ratio of the first map spot and the second map spot; it is also possible to use "whether the first map spot is associated with the data of immigrant relocation from other places" and "whether the overlap area value of the first map spot and the second map spot is greater than the first preset threshold, and / or whether the ratio of the overlap area value to the area value of the first map spot is greater than the second preset threshold" as two independent judgment methods for judging whether the land parcel to be processed meets the registration conditions. Users can adjust the order of the two judgment methods or decide to use any one of them according to specific usage needs and application scenarios, and no specific limitation is made here.

[0112] The second category, refer to step S103.

[0113] Step S103, acquiring and outputting target plot data according to the first plot and the overlapping portion, wherein the target plot data has attribute information of both the first plot and a reference unit set, and the reference unit set is composed of all the basic units in the first plot except the overlapping portion.

[0114] Users or real estate registration centers not only need to know whether the pending land parcel meets the registration conditions, but also need to know the specific reasons why the pending land parcel meets or does not meet the registration conditions. Figure 8 and Fig. 9 , Figure 8A schematic diagram of the overlap of a first image spot and a second image spot involved in a land parcel data processing method provided in an embodiment of the present application, Fig. 9 A schematic diagram of the fusion of attribute information of the first image spot and the reference unit set involved in a land parcel data processing method provided in an embodiment of the present application. Y is the first image spot, b is the second image spot of cultivated land type and is the overlapping part, and b divides Y into two different plots a and c, and a and c constitute the reference unit set mentioned above. Assume that the area of ​​Y is 10m 2 , the area of ​​b is 1m 2 , the areas of a and c are 4.5m 2 , satisfying the condition that "the land parcel occupies an area of ​​​​cultivated land less than or equal to 2 square meters", the result that the pending land parcel Y meets the registration conditions is output at this time. However, in order to meet the needs of users or real estate registration centers for subsequent processing of the pending land parcel Y, the FeatureMerger converter in FME can also be used to connect the attribute information of the first map and the reference unit set, and merge the attribute information of the two data together for output, so that the output result has both the attribute information before and after processing, which is convenient for subsequent recording, screening or other processing of the data. For example, the information that can be output includes but is not limited to: Y occupies an area of ​​b of 1m 2 、Non-occupied area is 9m 2 , the unoccupied area includes two sub-areas, both of which are 4.5m 2 The specific attribute types that need to be integrated can be customized according to specific usage requirements and application scenarios, and are not specifically limited here.

[0115] This application uses FME to perform data fusion and conversion of linear elements to surface elements on various types of second image spots, and then overlays the preprocessed second image spots and connects them with the data of immigrants relocation to determine whether the land parcel to be processed meets the registration conditions and outputs the corresponding judgment results. This application can quickly and accurately output the specific land occupation information and the processing results of whether it meets the registration conditions, thereby improving the efficiency of land parcel data processing.

[0116] Corresponding to the above method embodiment, see Fig.10 The present invention further provides a plot data processing device 1000, the plot data processing device 1000 comprising:

[0117] The data acquisition module 1001 is used to acquire at least one first map spot corresponding to the land parcel to be processed and at least one second map spot corresponding to the land of a non-land parcel type, wherein the first map spot and the second map spot are both composed of a plurality of basic units having the same first area value, and the attribute information of each of the first map spot and each of the second map spots includes a preset attribute type, an attribute value corresponding to each attribute type, and a coordinate value of each corresponding basic unit;
