[0052] Please refer to Figure 1 The embodiment of the present application provides a rural land second-round extension registration method, which comprises the following steps:

[0053] S1: Obtain the land transaction certificate number field and the contract management certificate number field in the rural land second-round extension registration data, extract the first character and the character length information, correspond the extracted content to the transaction class and the contract class field position in the field structure classification standard respectively, write the attribution information into the field registration content, and obtain the certificate number field attribution information registration item.

[0054] S2: Based on the contract type field content in the certificate number field attribution information registration item, extract the current record and the previous record corresponding to the extension period of the plot, read the current value and the previous value field direction, classify the period type according to the reading result, correspond the classified type to the plot code and unit number and write it into the registration field, and get the plot extension period type identification;

[0055] S3: Based on the plot number of the new period in the plot extension period type identification, extract the purpose field, the purpose classification field and the operation mode field, extract the content according to the field arrangement order, match the purpose standard classification, and write the corresponding purpose category result of the plot into the registration field structure to get the extension purpose adaptation combination information;

[0056] S4: Based on the plot number in the extension purpose adaptation combination information, extract the flow control, use period and reassignment condition content in the permission field, associate each permission field with the content of the purpose field, the purpose classification field and the operation mode field, and get the plot permission field adaptation result record corresponding to the field value in the association process;

[0057] S5: Based on the data number with the state of adaptation in the plot permission field adaptation result record, extract the unit code field and the extension period field information, add the path field content to the path table according to the direction logic mapped by the period segment, and then fill in the path node structure with the corresponding values of the purpose field and the permission field, to get the extension path structure hanging record.

[0058] The certificate number field attribution information registration item includes first character information, character length information, field attribution classification, field position identification, the plot extension period type identification includes extension period current value, extension period previous value, field direction category, period segment mapping type, plot identification code, unit identification number, the extension purpose adaptation combination information includes purpose field content, purpose classification content, operation mode content, purpose standard classification result, the plot permission field adaptation result record includes flow control parameter, use period setting, reassignment condition parameter, field value adaptation result, and the extension path structure hanging record includes path addition field, path node structure content, unit code corresponding value, extension period corresponding value.

[0059] The specific steps of S1 are:

[0060] S101: Obtain the land transaction certificate number field and the contract management certificate number field in the rural land two-round extension registration data, extract the first character and length value of the field and the field feature in the structure classification standard, match the starting character and length parameter position, and get the field structure matching result;

[0061] Firstly, the source data content is positioned and called. In actual application, two table data files such as "registration table A.xlsx" and "registration table B.xlsx" can be called, and in operation, each data record in the "land transaction certificate number" column and the "contract management certificate number" column is read respectively, the first character of each record is extracted, that is, the first character of the string is called, for example, the first character of "J320109" is "J", and then the length value is obtained, which can be directly determined by calling the length attribute of the string, for example, 7 bits; then, the obtained first character and length value are compared with the field structure classification standard of the transaction class and the contract class field characteristics content respectively, the standard is generally given in the form of a table, for example: the transaction class field requires the first character to be "T" or "J", and the length to be 7 or 9, and the contract class field requires the first character to be "C" or "P", and the length to be 8 or 10; each extracted content is matched, that is, it is judged whether the first character contains the specified transaction class or contract class allowed value list, and whether the length value is located in the specified range, assuming that a record has a first character "J" and a length of 7, it meets the two characteristic requirements of the transaction class field; if another record has a first character "C" and a length of 8, it is matched to the contract class field; in this process, the execution of the judgment action involves two parallel processing operations of first character list matching and length range judgment, after all fields complete the characteristic comparison operation, the matching state is recorded in the result, that is, whether to meet the condition is recorded as "transaction class" or "contract class", and in the processing process, if a record with a first character that does not meet the condition but a length that meets the condition is encountered, such as a first character "Z" and a length of 7, the matching fails and is not included in any field class; finally, combined with the data record index, the matching result of each record and its original data are stored correspondingly to obtain the field structure matching result.

[0062] S102: Based on the matching content in the field structure matching result, the field name of the contract class and the transaction class standard is screened, the first character and the length range are screened, and each field is corresponded to the registration area according to the order shown in the classification standard, to obtain the field classification attribution processing result;

[0063] Firstly, read the matching state table recorded in the previous stage, which contains the first character and length value of each certificate number record and its classified field type label, filter all field names identified as "contract class" or "transaction class" in the result, for example, field "J2308177" is transaction class, "C90182710" is contract class, and determine whether the field type label of each record is the target category during the filtering process. If it is of other types, it is skipped and not processed. Then extract the first character and length value of these filtered fields, for example, the first character of transaction class record "J2308177" is "J" and the length is 8; the first character of contract class record "C90182710" is "C" and the length is 9. Then, according to the first character range and length range allowed by the classification standard of transaction class and contract class, judge whether it still meets the feature requirements set by the latest version of the classification standard. If it is found that the length of a field exceeds the allowed upper limit, such as the maximum allowed length of contract class is 10 and the extracted field is 12 bits, it should be excluded in this round of processing. After judgment, only the fields that meet the two standards are reserved, and these fields are sorted according to the field order number in the classification standard, such as the classification standard requires the order of contract class fields: C class number first, P class number last, then sort the fields matched as contract class according to the first characters "C" and "P" after classification, and then arrange them according to the original record order. The classified fields can be one-to-one corresponding to the field order number or other unique identifier and the field order of the registration area. The registration area can be the field area number marked in the land management registration table, such as "area field 01" to "area field 20". If a field is the third item in the contract class field, it corresponds to the third item in the area field order. In the operation, the filtered field content is directly written to the corresponding area field position, keeping the field value unchanged and recording its class label and order number information in the target area, forming a one-to-one matching field distribution state, and finally obtaining the field classification and attribution processing result.

[0064] S103: Based on the attribution content in the field classification and attribution processing result, extract the field name and attribution type, write its content to the corresponding position of the field registration structure table, and associate the attribution type to the original registration field block to obtain the certificate number field attribution information registration item;

[0065] First, the field classification attribution processing result is expanded item by item according to the record number, and the field name information and the corresponding attribution type content contained in each record are extracted. The field name is generally composed of the table header or field identifier of the certificate number item, and the attribution type is the category that the field is identified as in the classification standard, such as the contractor class or the transaction class. Then, the extracted field name and its attribution type information are combined to form a field attribution record. The field name information in the field attribution record is used to locate the corresponding column mark number in the field registration structure table. The column mark number is usually the structure sequence number based on the data source table. If the field registration structure table uses field alias instead of the original table header form, additional field alias mapping conversion of the field name is required. The attribution type information value is inserted at the located registration position. After the field attribution record is processed item by item, the assignment operation of the registration structure table is completed. For example, if the attribution type of the field "HTBH" is "transaction class", "transaction class" can be written in the "HTBH" corresponding column mark position in the field registration structure table. Matching linkage of the original registration field block is required in the subsequent operation. According to the updated attribution type information in the field registration structure table, the corresponding content of the same field name in the original registration data is found, and the attribution field position in the corresponding record is assigned to the same attribution type, forming a consistent mapping between the attribution type and the original field. The fields in the original registration field block may include "contract number", "contractor number", etc. Each field needs to be matched with the field name in the field registration structure table. The matched fields can be directly corresponding by the field name or can be corresponding by cross comparison using field alias. If multiple field names correspond to the same attribution type, the same type value can be recorded in the attribution type field. For example, if "contract number" and "contract number" are both determined as transaction class fields, they can be uniformly assigned as "transaction class" in their original field block. After the above operations, the certificate number field attribution information registration item is obtained.

[0066] The specific steps of S2 are:

[0067] S201: Based on the contractor class field content in the certificate number field attribution information registration item, the corresponding land block code and land block extension period field are extracted, the positions of the current registration value and the previous registration value in the data table are located, the time attribute of the field is collected, the time direction difference between the current value and the previous value in the time sequence is extracted, and the field time direction is obtained.

[0068] First, all the field names corresponding to the contract type fields are extracted from the registration items, the actual position of each field name in the data record table is located, and the plot code field associated with it in the data interval is identified. The plot code is used as a unique identifier to identify and confirm the record ownership of different plots. After identification, the exact row number of each record in the data table is confirmed by the plot code, and then the original content of the extension period field in the same row is extracted. This field usually represents the description information of the extension period or use period of the plot. Then, by comparing the plot code, the corresponding historical registration record is found in the data table, the last data version of the same plot as the current registration item is identified, the content of the extension period field in the historical record is extracted, and the historical record and the current record are set in pairs. The column number and row number position of the record in the table are determined in chronological order to confirm the arrangement order of the time field. After completing the position positioning, the time limit description in the two fields is identified, and the time start element and time end element involved are extracted. If the record form uses stage description, fuzzy period expression or other character modification, it needs to be converted into a standard expression form, such as abstracting descriptions such as "after a certain year" "before a certain period" "long-term" into corresponding logical sequence numbers for unified numbering and archiving. Then, the start element of the current record is compared with that of the previous record. If the start element number of the current record is greater than that of the previous record, it is judged as forward, if it is less than that of the previous record, it is judged as reverse, and if they are equal, the end element number is compared to determine the time direction of the field. In the whole process, attention should be paid to the processing of time limit records with multiple expression formats, and the same numbering conversion method should be used for different expression types to maintain the consistency of the judgment standard. Finally, the time direction of the field is obtained.

[0069] S202: Based on the direction result in the field time direction, the dominant direction value of the direction sequence in the current period is calculated. The record with positive dominant direction is corresponding to the new period, and the record with reverse dominant direction is corresponding to the reduced period, to obtain the period type attribution result;

[0070] The calculation formula of the dominant direction value of the direction sequence in the current period is as follows:

[0071] ;

[0072] Wherein, represents the dominant direction value of the direction sequence in the current period, represents the index number of the direction result record, represents the total number of direction records in the current period, represents the direction value of the first direction result, represents the time value of the first direction record, the arithmetic mean of the direction record times in the current period, the arithmetic mean of the direction record times in the current period, the frequency of occurrence of the direction record in the current period, the sum of the direction record times in the current period, the sum of the direction record times in the current period, the sum of the direction record times in the current period, the sum of the direction record times in the current period, the normalized stable control constant;

[0073] In the current period, the number of direction result records collected is Each record shows the following:

[0100] Period judgment and technology combination:

[0101] : add a period, : reduce the period;

[0102] Result interpretation and numerical significance: the dominant direction value obtained by this calculation is , based on the weighted trend amplification processing and nonlinear normalization operation of all direction record data in the current period, the numerical value represents the strength and direction aggregation degree of the direction trend in the period;

[0103] Formula innovation point explanation:

[0104] The usefulness of the formula is that by introducing the square root term based on the field time offset , combined with the direction strength , direction frequency and local fluctuation correction term , construct the product square trend item, and use the denominator normalization structure of , enhance the stability of trend response, reduce the amplitude of single point interference, and perform stable quantization of direction trend nonlinear enhancement and period state judgment.

[0105] S203: Based on the classification state in the period type attribution result, write the period type information into the corresponding block registration structure field position, fill in the period field structure column corresponding to the period state and unit number and block code field, and obtain the block extension period segment type identification;

[0106] First, extract the period type information marked by the classification state field. The period type information is the key data content describing the change of the period state in the extension registration. Common values are, for example, "continuation type" and "restart type". After extracting the period type field, the block code field associated with the period type needs to be located in the block information data table. The block code is a unique identification field, which can be used to determine the target row position in the block registration data set. At the same time, extract the information of each column in the registration structure field in the current row and confirm the field order. Identify the corresponding column number of the period type field in the current structure, for example, the period field is in the sixth column position of the structure table. Fill in the period type content in the corresponding cell position of the column. Further locate the unit number field corresponding to the block. The unit number and the block code have a one-to-one correspondence, which is used to represent the unit to which it belongs. In the block registration structure, the unit number is usually arranged in a fixed field segment. The relative position needs to be confirmed according to the field header information. Map the classification type value indicated by the period state to the period field column corresponding to the block code and unit number row in turn, and compare it with other period field types in the same batch of block data to confirm the consistency of its classification attribution and registration structure integrity. In actual operation, for example, for the block DK30561, if its period type is "continuation type" and the unit number is UC871, fill in the value of the period type in the period field position of DK30561 corresponding to UC871. Finally, complete the corresponding filling between the classification state and the unit code and the block code, and obtain the block extension period segment type identification.

[0107] The specific steps of S3 are:

[0108] S301: Based on the block number of the newly added period in the block extension period segment type identification, extract the purpose field, purpose classification field and operation mode field, collect the field code and description information according to the field arrangement order, extract the field order and registration structure position content, and obtain the purpose field basic extraction result;

[0109] Firstly, the land number list involved in the new period is located, and by comparing the current period segment identification data with the historical period segment identification data, the land number items not appearing in the previous registration but appearing in the current data are identified. After extracting each land number in the result, the corresponding row content in the land information registration table is read in turn, and the corresponding purpose field, purpose classification field and operation mode field are further extracted from the row. The arrangement order of the three fields needs to be determined according to the field definition sequence of the registration table. After confirming the column numbers of each field in the field list, the field code and field description information in the corresponding column are extracted. The field code is the defined number field in the registration structure, such as the purpose code YT001 and the operation mode code ZYF002. The field description information is the corresponding text content of the code, such as "orchard planting" and "manual plowing". After the extraction is completed, the field arrangement logic and the column order position of the registration structure in the data table are further analyzed according to the registration table structure sequence. The position of each field in the table header name sequence is determined by reading the table header information, and it is verified whether the field content is consistent with the field value corresponding to the land number. For example, for the land number DK10472, the purpose field code is YT001, corresponding to the description "grain planting", and the operation mode field code is ZYF001, corresponding to the description "mechanical seeding". It is also confirmed that the three fields are arranged in the seventh column, the eighth column and the ninth column in the table. Combining the field ordering and the field value, the order relationship between the fields is arranged to form the field arrangement details based on the registration structure sequence, and finally the purpose field basic extraction result is obtained.

[0110] S302: Based on the field code in the purpose field basic extraction result, the corresponding amount of the field code and the classification item in the standard classification path is calculated, the corresponding amount reaching the field matching classification path is screened, the classification path content is mapped to the corresponding field group, and the purpose field classification attribution result is obtained.

[0111] The calculation formula of the corresponding amount of the field code and the classification item in the standard classification path is as follows:

[0130] Result interpretation and numerical significance:

[0131] The calculation result 9.846 represents the weight value of the field attribution, reflecting the deviation and matching degree between the classification path and the field encoding, mapping to the corresponding field group, completing the attribution task of the field classification of use;

[0132] Formula innovation point description:

[0133] The usefulness of the formula is that by introducing the standard deviation of field encoding and weight, combined with constant term for normalization processing, it improves the adaptability of the classification path. Through the introduction of standard deviation, the formula reduces the influence of data fluctuation on the classification result, and through the setting of weight value, it can be adjusted according to the key of the field, ensuring the matching of the classification path.

[0134] S303: Based on the content of the classification result in the use field, the classification result is filled in the corresponding block number, the use classification field and the operation mode field content are written in the registration column, and the extension package use adaptation combination information is obtained;

[0135] First, the classified field results are merged, and the block number and corresponding attribution category in each record are extracted, for example, the attribution category corresponding to the block number DK30317 is "planting", the number is inserted into the corresponding field position in the registration structure table according to the number, and the position column number of the registration field can be determined according to the field position mapped by the attribution category. Subsequently, the original registration values of the use classification field and the operation mode field corresponding to the same number are extracted, and the field values are usually composed of codes and descriptions, such as the use classification field FL107, the corresponding description is "vegetable planting", and the operation mode field ZY205, the corresponding description is "drip irrigation farming". After obtaining the contents of the two fields, the codes and description contents are written into the preset column number positions in the original registration structure table, and the column number can be determined according to the field classification registration template structure, such as the use classification field in the tenth column and the operation mode field in the eleventh column. For multiple block numbers, the operation needs to be performed for each record, and the batch connection diagram of the number and field content is formed. For example, if another record with the number DK30318 has the attribution category "breeding", the use classification is FL206 "aquaculture", and the operation mode is ZY312 "fence breeding", the three data are sequentially filled into the corresponding column positions, and correspond to the above record. Ensure that each attribution category result can be mapped to a specific field and accurately positioned to the structure field column position associated with the corresponding block, and finally obtain the extension package use adaptation combination information.

[0136] The specific steps of S4 are:

[0137] S401: Based on the block number in the extension package use adaptation combination information, the flow control, use period and redistribution condition contents in the permission field are extracted, the permission field content is read according to the field arrangement order, and the corresponding block number information is obtained. Get the classification result of the permission field;

[0138] First, determine the corresponding plot code of each record, for example, the record of plot number DK40121, call the index position of the number in the extension use adaptation combination table, according to the order of the authority field setting, extract the three authority information fields corresponding to the number, that is, the flow control field, the use restriction field and the redistribution condition field, and read the corresponding values in the field order. In actual operation, the flow control field may be "restricted transfer", the use restriction field is "restrictive use", and the redistribution condition field is "natural update". The read authority field content should be combined with the arrangement order in the field setting table, and the same plot number record should be sequentially entered into the same plot number record in the preset order. Through the order, the format of the authority information under different plot numbers is uniformly processed to ensure that there is no cross coverage or omission between fields. For example, when processing another record of plot number DK40133, if the read value of the authority field is "allowed transfer", "standard use" and "collective redistribution" in turn, the authority information line under the number should be entered according to the order. If there is a null value or a format inconsistent field in the read process of the authority field, it should be skipped or null value filled according to the field definition rule to avoid affecting the subsequent classification operation due to format exception. After the above information matching is completed, the read authority field content and its corresponding plot number are mapped to form a one-to-one data index, which is uniformly processed in the authority classification information set, and finally the authority field classification result is obtained.

[0139] S402: based on the classification result of the authority field, the flow control field corresponds to the use field, the use year limit field corresponds to the use classification field, and the redistribution condition field corresponds to the operation mode field. Read the content according to the field correspondence to get the field corresponding comparison content;

[0140] First, locate the content of the permission field recorded in each plot record, for example, the record of plot number DK40207, in the permission field classification table, get its flow control field "limit flow", use time field and redistribution condition field "collective decision" in turn, then call the use field table corresponding to the plot number, extract the use field "fruit planting", use classification field "economic forest class" and operation mode field "manual weeding" under this number, in the field corresponding operation, the permission field should be respectively corresponding to the use field content according to the fixed order, specifically, the flow control field corresponds to the use field, the use time field corresponds to the use classification field, and the redistribution condition field corresponds to the operation mode field. After the connection of the three groups of fields is completed, the field content is read, for example, when "limit flow" is connected with "fruit planting", the field attribute matching table is called to read the function type parameters to which the two fields belong, to judge whether they belong to the same or whether they belong to the cooperative application type. If the attribute of the read field matching result is "non exclusive", it is determined that the corresponding relationship is valid. In actual operation, combinations such as "allow flow" and "food crops" or "collective decision" and "machine plowing and sowing" can also be processed. During the process, it is necessary to ensure that the field reading order and the field arrangement rule remain consistent. If any field fails to read the corresponding value or the read value is empty, the current matching record will be excluded from the corresponding set and marked as a to-be-processed state. Finally, the corresponding reading operation of the permission field and the use field of all plot records is completed, and the field corresponding comparison content is obtained.

[0141] S403: based on the field corresponding comparison content, fill in the matching between the field values in the permission state field, and locate it with the plot information to get the plot permission field adaptation result record;

[0142] First, the parcel number is traversed for each read-out comparison record, and the associated comparison result content is called as the index parameter. For example, the record with parcel number DK40308 has field comparison content "use field consistent with flow control field", "use classification field inconsistent with use period field", and "operation mode field consistent with redistribution condition field". The unified judgment is made on the matching state of the three groups of fields. The corresponding results of the same field values are regarded as "match", and the corresponding results of different field values are regarded as "not match". Each group of judgment results is filled into the permission state field column according to the field order. If there is no matching relationship or the matching state is empty in the corresponding permission state position, "missing" mark is filled in the corresponding permission state position. In the filling process, the field order should be fixed as flow control field, use period field and redistribution condition field to avoid data positioning deviation caused by disorder of field order. Then, the judgment results in the permission state field are corresponded with the original parcel information one by one to ensure that the parcel number and its corresponding permission matching result keep unique mapping. In the operation process, it is necessary to check whether the parcel number field is repeated or the corresponding field content is incomplete. If there is field fracture or number mismatch, the current record writing operation should be stopped and listed in the record exception list. The "match", "not match" and "missing" contents in the comparison result are uniformly put into the parcel information table. The permission field matching state value is added to each parcel record. Finally, the state filling process after full field comparison is completed, and the parcel permission field adaptation result record is obtained.

[0143] The specific steps of S5 are:

[0144] S501: Based on the data number with state "adaptation" in the parcel permission field adaptation result record, the unit code field and the extension period field content are extracted. The period section direction is linked with the unit code field to analyze and add the path field according to the number mapping order to obtain the path direction addition content.

[0145] First, all plot numbers with the status field as "adapted" are filtered in the adapted record set, and the corresponding unit code field and expiration period field values are retrieved from the associated data table based on the number field in each record. It is confirmed whether the unit code field is completely filled and has no missing items. Then, based on the linkage rules between the unit code field and the period segment direction, the direction value recorded in the period segment field is called, such as the period segment direction being "forward" or "backward". The corresponding unit code is arranged in order according to the numbering rules. If the direction is forward, the unit code is appended in ascending order. If the direction is backward, the unit code is appended in descending order. Before performing the appending operation, it is necessary to judge according to the code level in the unit code field. If the unit code is "UA1201", it should be confirmed that "UA" is the administrative prefix and "1201" is the unit number. The unit number is parsed and matched with the position in the order chain according to the period segment direction. Then, the path field is numbered and filled according to the order of the number mapping. The path field is kept continuous in the appending operation to avoid empty numbers. If there is a number jump in the continuous numbering process, the missing position is marked with "null value". Then, the missing position is identified in the data tail segment. During the whole process, batch splicing operation should not be used and each data should be processed and written back to the path field separately. For example, if the plot number is DK50102, the corresponding unit code is UA1302, and the period segment direction is backward, then "UA1303", "UA1302", "UA1301" should be filled in the path field in order. The path segment number is determined by the year limit value in the expiration period field. If the year limit is 3 years, the path segment is 3 bits, and the path number is filled from the last segment to the first segment position. Finally, the direction segment path and the number segment are added to the record set table to get the path direction addition content.

[0146] S502: Based on the path direction addition content, read the current field value in the purpose field and the authority field of the corresponding plot. According to the corresponding order of the field structure, the field value is positioned to the node structure field and filled in the corresponding position to get the field mapping filling result.

[0147] First, the additional content recorded in the plot number is extracted as an index parameter, and the use field and permission field content associated with the plot number is retrieved in the data table one by one. During reading, the use field, flow control field, use period field and redistribution condition field are grabbed in sequence according to the field order. The extracted results are arranged into use field value set and permission field value set respectively, and numbered according to the field order. For example, the record of plot number DK30507, whose use field is "planting land", the permission field content is "transferable, 5 years, no redistribution" in turn. Then, according to the field arrangement order defined by the field structure, the use field is positioned as the first field in the first position of the node structure field, and the permission field is written in the subsequent positions of the node structure field in order, that is, "transferable" as the second, "5 years" as the third, and "no redistribution" as the fourth. During the process, the fields must not be sorted or misplaced. If a field is empty, a "null" mark is written in the node field position to ensure that the total length of the structure table field is consistent with the field structure definition. Then, according to the segment number in the path field and the plot number, the combination positioning is carried out. For example, the path segment is PD03, and the plot number is DK30507. Then the node structure field identifier should be PD03-DK30507. The structure field is filled into each data slot under the identifier field. After filling, the result is marked as "filling completed". During each field writing process, the field type consistency of the field type and the target slot type is judged. If the field value type is text but the target slot is numerical format, the data conversion rule should be called before writing to convert the field value format, such as converting "5 years" to integer value "5" before writing. Finally, the mapping filling of all node field contents is completed, and the field mapping filling result is obtained.

[0148] S503: Based on the field mapping filling result, the path field content and the node field structure are gathered, the content is written according to the number information, and the extension package path structure hanging record is obtained.

[0149] First, the path field content and node field structure content corresponding to each data in the record are extracted, wherein the path field is composed of path number and segment number, and the node field structure is composed of structure bit, field value, field source, etc. During operation, path groups are established in the order of path field, for example, the path field is PD07-03, and the group name is set as path PD07-03 group. In the group, all node field structure contents from the same path field are summarized. Each structure field content is read one by one, and the field bit and field value are combined to form a mapping item. For example, the first bit is "planting land", the second bit is "transferable", and the third bit is "8 years". The mapping item "1: planting land, 2: transferable, 3: 8 years" is generated. Then, according to the field source information recorded in the node field, the land parcel number to which the data belongs is confirmed. For example, a structure field identified as PD07-03-DK51105 belongs to land parcel number DK51105. During the writing process, the path number and land parcel number need to be combined to generate a hanging identification field, such as PD07-DK51105. Then, the corresponding field structure content is hung in the record unit under the identification field to ensure that the hanging records of the same land parcel under different paths are not covered. For the case of multiple path aggregation of the same land parcel, for example, DK51105 appears in PD07-03 and PD08-02, respectively, PD07-DK51105 and PD08-DK51105 two hanging record items are generated, and the path field content and node field structure are written. During the writing process, it needs to be judged whether each record has null value or incomplete field. If the field value is missing, it is marked as "empty" in the mapping item, such as "2: empty", indicating that the position is not filled. After the final aggregation is completed, the hanging record marked as "extended path structure hanging record completion" state is generated by combining the path field and node field structure, which is used as the basis for subsequent structure tracing and path extension. The extended path structure hanging record is obtained.
