[0013] This application provides a method for digitizing the two-line range of immovable cultural relics, which solves the pain points and difficulties of the existing two-line cultural relics protection, such as cumbersome fixed-point methods and unclear identification of the two-line ranges. It realizes that this method and system can expand and innovate the intelligent application of cultural relics two-line data, empower cultural relics inspection and law enforcement work, and solve the pain points of cumbersome fixed-point methods, unclear identification of the two-line ranges, and difficulty in law enforcement inspections in previous cultural relics protection work.

[0014] Application Overview

[0015] There are pain points and difficulties in the two lines of cultural relics protection, such as the cumbersome method of fixing points and unclear identification of the scope of the two lines. Relevant personnel are unable to make appropriate judgments on the inspection locations based on the existing two-line demarcation scope, and are unable to make overall plans for cultural relics inspections and law enforcement work. It is difficult to solve the pain points of previous cultural relics protection work, such as the cumbersome method of fixing points, unclear identification of the two-line scope, and difficulty in law enforcement inspections.

[0016] In response to the above technical problems, the overall idea of ​​the technical solution provided by this application is as follows:

[0017] The present application provides a technical solution, in which the method includes: combining standard data layers with a GIS system for data registration; drawing points based on standard data through the GIS system and picking up the longitude and latitude of each point; processing multi-point longitude and latitude data to form a two-line protection range layer; using an on-site point calibration tool to collect current positioning data in real time and obtain the current longitude and latitude; comparing and correcting the on-site data with the drawn data; providing on-site law enforcement personnel with a digital two-line protection range mark to quickly determine whether the current position is within the scope of the cultural relic itself, the protection scope or the construction control zone, and providing different color marks in different ranges for prompts to improve the recognition of the current position.

[0018] After introducing the basic principles of the present application, various non-limiting implementation methods of the present application will be specifically introduced in conjunction with the drawings in the specification.

[0019] Example

[0020] like Figure 1 As shown, the present application provides a technical solution, wherein the method includes:

[0021] S1. Data registration is performed with standard data layers combined with the GIS system;

[0022] Specifically, by registering the standard data layers with the GIS system, relevant personnel can use GIS software to fit the standard data, establish connections, and stitch them together. This helps identify common data structures and enable more accurate matching of these structures, enhancing the method's ability to extract local point information and determine ranges.

[0023] S2. Use the GIS system to draw points based on standard data and pick up the latitude and longitude of each point;

[0024] Specifically, by using the GIS system to draw standard data points, it is ensured that this method can be used for mapping based on existing geographic data. The graphics elements of the standard data can be drawn and modified at will using relevant tools, and every detail within the double-line range can be flexibly modified, thereby improving the functionality and practicality of this method.

[0025] S3. Process multi-point latitude and longitude data to form a two-line protection range layer;

[0026] Specifically, by processing the latitude and longitude data of multiple points, it can be ensured that the processed latitude and longitude data can be better interactively integrated with the GIS system, making it easier for relevant personnel to establish a two-line protection range layer through this method, ensuring that relevant personnel can understand the specific scope of the two-line protection zone in the law enforcement area through this method, and improving the law enforcement effect and efficiency of relevant personnel.

[0027] S4. Use the on-site point calibration tool to collect current positioning data in real time and obtain the current latitude and longitude;

[0028] Specifically, by using on-site point calibration tools to collect on-site positioning data and longitude and latitude, it is helpful to ensure the accuracy of on-site collected data, making it easier for relevant personnel to obtain accurate analysis and judgment results after importing the on-site data, thereby improving the feasibility of this method in actual on-site law enforcement processes.

[0029] S5. Compare and correct the field data with the mapped data;

[0030] Specifically, by comparing and correcting the field data and the drawn data, it is helpful to improve the accuracy of the method in judging the actual situation on site, increase the scope of logical analysis of the method when making judgments, expand the overall scope of application of the method in actual field use, and improve the overall practicality of the method when used.

[0031] S6. Provide on-site law enforcement personnel with digital two-line protection range identification to quickly determine whether the current location is within the scope of the cultural relic itself, the protection range or the construction control zone. At the same time, different color identification is provided in different ranges to improve the recognition of the current location.

[0032] Specifically, this judgment method is helpful in providing on-site law enforcement personnel with a clear two-line protection range identification, which makes it easier for law enforcement personnel to make clear judgments on the actual situation at the law enforcement site based on this method, and solves the problems of cumbersome fixed-point methods, unclear identification of two-line ranges, and difficulty in law enforcement inspections in previous cultural relics protection work.

[0033] Further, such as Figure 2 As shown, in S1, the data registration specifically further includes the following steps:

[0034] S101. Add the feature class that already has a coordinate system and the feature class that needs to be corrected to ArcMap;

[0035] S102. Set the data to be corrected in the spatialadjustment toolbar menu;

[0036] S103. Set the correction method;

[0037] S104. Set the combined environment;

[0038] S105. Click the Replace Connection tool;

[0039] S106. Click a point on the element to be corrected, click a corresponding point on the reference element, and establish a replacement connection;

[0040] S107. Click Adjust under the SpatialAdjustment toolbar menu to complete data registration.

[0041] Specifically, by importing the data into ArcMap and correcting the data with the SpatialAdjustment toolbar, while ensuring the accuracy of the actual application range of the data, the accuracy of the data used by this method can be further improved, avoiding errors in the original data range that may cause misjudgment of the two-line range when the method is used, affecting the accuracy of law enforcement by relevant personnel.

[0042] Further, such as Figure 3 As shown, in S2, drawing the points specifically further includes the following steps:

[0043] S201. Create a standard data point folder;

[0044] S202. Open the MAPGIS main menu and perform system settings;

[0045] S203. Input point data and convert data type;

[0046] S204. Create a new workspace, vectorize the graphic data, load it into a raster file, and trace the data points.

[0047] Specifically, by creating a file in GIS based on standard data points and obtaining longitude and latitude information through the GIS system, it is helpful to improve the accuracy of the original data of this method and improve the effectiveness of this method in actual use.

[0048] Furthermore, if Figure 4As shown, the S3 specifically also includes a two-line drawing algorithm:

[0049] S301. Get the longitude and latitude data of all points through setPolygonslist; and classify the two lines according to the different point types, and draw the two-line legend according to the classification attributes and point positions;

[0050] S302. The original point marks are displayed in the legend to provide a reference for the correction and processing of on-site point data.

[0051] Specifically, obtaining the longitude and latitude data of all points through setPolygonslist helps users to classify and analyze the types of judgment points, further improving the accuracy and effectiveness of this method.

[0052] Furthermore, in S302, the data correction specifically further includes the following steps:

[0053] S30201. Extract actual data and theoretical data separately and create files;

[0054] S30202. In the error correction subsystem, load the previously prepared acquisition file;

[0055] S30203. Open or create a control point file and collect control points;

[0056] S30204. Observe the correction effect and browse the control points;

[0057] S30205. Correction of on-site point data;

[0058] S30206. Save the corrected on-site point data.

[0059] Specifically, by calibrating the latitude and longitude data of multiple points, it is helpful to further improve the accuracy of the original data used by this method and ensure the range accuracy when using this method.

[0060] Further, such as Figure 5 As shown, in S4, performing on-site point calibration specifically further includes the following steps:

[0061] S401. Open the base station host;

[0062] S402. Open the mobile station host and hands;

[0063] S403. Set relevant calibration measurement configuration;

[0064] S404. Calibrate the instrument by two-point measurement;

[0065] S405. Input known coordinates;

[0066] S406. Stake out the coordinates of relevant points;

[0067] S407. Export measurement point results.

[0068] Specifically, it is helpful for users to accurately measure and collect actual data on site based on the GPS locator.

[0069] Furthermore, if Figure 6 In the above-mentioned S5, the method further includes determining whether the longitude and latitude of the current position are within the range by using an algorithm:

[0070] S501. Loop to determine the latitude and longitude (x, y) of all points;

[0071] S502. The two endpoints of the current edge of the two-line legend are known values ​​(x1, y1) and (x2, y2). If y lies between y1 and y2, assume that the intersection of the horizontal line passing through the point to be determined (x, y) and the current edge is (x_intersect, y_intersect). If y_intersect = y, then there are two similar triangles with a common vertex angle, and width / width = height / height: |x1-x2| / |x1-x_intersect| = |y1-y2| / |y1-y|.

[0072] S503. Return whether the result is within the range.

[0073] Specifically, by establishing a two-point coordinate system, the method facilitates range determination by importing the determination point, simplifies the process of determining the determination point by the method, and improves the stability and accuracy of the method when in use.

[0074] Furthermore, in S503, if |x1-x2| / |x1-x_intersect|=|y1-y2| / |y1-y|, it is determined that the judgment point (x, y) is within the double-line range; if |x1-x2| / |x1-x_intersect|≠|y1-y2| / |y1-y|, it is determined that the judgment point (x, y) is not within the double-line range.

[0075] Specifically, by comparing the specific positions of the judgment points, it is convenient to determine whether the judgment points are within the double-line range through this method.

[0076] In summary, the method for digitizing two-line ranges of immovable cultural relics provided by this application has the following technical effects:

[0077] 1. This application provides a method for digitizing the two-line range of immovable cultural relics. The standard data layer is combined with the GIS system for data registration; the GIS system draws points based on the standard data and picks up the longitude and latitude of each point; multi-point longitude and latitude data are processed to form a two-line protection range layer; the on-site point calibration tool is used to collect current positioning data in real time to obtain the current longitude and latitude; the on-site data is compared with the drawn data and corrected; a digital two-line protection range mark is provided for on-site law enforcement personnel to quickly determine whether the current position is within the scope of the cultural relic itself, the protection range or the construction control zone. At the same time, different color labels are provided for prompts in different ranges to improve the recognition of the current position, solving the pain points and difficulties of the existing two-line cultural relics protection, such as cumbersome fixed-point methods and unclear identification of the two-line ranges. It ensures that users can use this method to combine the technical means of geographic coordinate point alignment, spatial coordinate system conversion, and position offset calculation, combined with map ranging, multi-layer overlay and Beidou-compatible positioning technology, to expand and innovate the smart application of cultural relics two-line data, empower cultural relics inspection and law enforcement work, and solve the pain points of cumbersome fixed-point methods, unclear identification of the two-line ranges, and difficulty in law enforcement inspections in previous cultural relics protection work.

[0078] 2. Due to the adoption of setPolygonslist to obtain the latitude and longitude data of all points; through the current, and according to different point types, the two-line categories are judged and divided, and the two-line legend is drawn according to the classification attributes and point positions. The original point marks are displayed in the legend, providing a reference for the correction and processing of on-site point data, ensuring that the processed longitude and latitude data can be better interacted and integrated with the GIS system, so as to facilitate the establishment of the two-line protection range layer by relevant personnel through this method, ensuring that relevant personnel can understand the specific scope of the two-line protection zone in the law enforcement area through this method, and improve the law enforcement effect and efficiency of relevant personnel.

[0079] 3. Due to the use of a loop to determine the longitude and latitude (x, y) of all points, the two endpoints of the current edge of the two-line legend are known values ​​(x1, y1) and (x2, y2). If y is between y1 and y2, assuming that the intersection of the horizontal line through the point to be determined (x, y) and the current edge is (x_intersect, y_intersect), and y_intersect = y, there are two similar triangles with a common vertex angle, width / width = height / height: |x1-x2| / |x1-x_intersect|=|y1-y2| / |y1-y|. The result returns whether it is within the range, which improves the accuracy of the method in judging the actual situation on site, increases the scope of logical analysis of the method when making judgments, expands the overall scope of application of the method in actual on-site use, and improves the overall practicality of the method when used.
