Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

1 , a first embodiment of the present invention provides a method for displaying geographic entity information based on an identification code, including the following steps:

S11, calculate the location code of the geographic entity according to the geographic coordinates and spatial scope of the geographic entity;

S12, obtain the type code of the geographic entity according to the geometric type and spatial position of the geographic entity;

S13, obtain the classification code, time code and sequence code of the geographic entity;

S14, according to the classification code, the time code, the sequence code, the location code and the type code to generate the identity number of the geographic entity;

S15, obtain the name information and website information of the geographic entity;

S16: Generate an identification code of a geographic entity according to the identification number, the name information and the website information, and display the information of the geographic entity according to the identification code.

In step S11, the location code of the geographic entity is calculated according to the geographic coordinates and spatial range of the geographic entity. In this embodiment, based on the multi-dimensional space division of quadratic recursion on the earth plane and high binary recursion, this embodiment refers to a set of large-scale global, down to the center of the earth, up to 50,000 km above the ground, and small to The 0-32-level grid system of centimeter-level whole degree, whole minute and whole second stores geographic entities of different sizes.

In step S12, the type code of the geographic entity is obtained according to the geometric type and spatial position of the geographic entity. The type code indicates the geometric type and spatial location of the geographic entity. Geographic field geometry types are divided into points, lines, areas, and volumes, which are represented by P, L, Y, and B, respectively. Geographical physical space locations mainly include ground, above-ground, underground, and mixed, which are represented by G, A, U, and C, respectively.

In step S13, the classification code, time code, sequence code, name information and website information of the geographic entity need to be obtained.

The classification code is obtained by classifying the geographic entity according to the type of the geographic entity. In this embodiment, the classification code is composed of an eight-digit sequence of numbers, and Appendix 4 is the geographic entity classification code table, which specifically includes the following: 1 digit for category, represented by numbers 1-9; 1 digit for subcategory, represented by numbers 1-9 Representation; 2 digits for major categories, represented by numbers 10-99; 2 digits for medium classes, represented by numbers 00-99; 2 digits for small categories, represented by numbers 00-99. Among them, based on the "Guangzhou Urban and Rural Planning Basic Geographic Information (1:500 1:1000 1:2000) Data Standard", the high-order code (1-6 digits) adopts GB/T 25529-2010 geographic information classification and coding The rules for the compilation of high-order codes (see Table 1 for the list of geographic entity categories and sub-categories), and low-order codes (7-10 digits) refer to GB/T 13923-2006 Basic Geographic Information Element Classification and Code Subclasses and GB 50137-2011 Classification coding rules. Exemplarily, taking the Canton Tower as an example, the classification code is 11023105.

In this embodiment, the time code is the year of the year when the geographic entity was first collected, surveyed, or database built, etc., and different lengths can be used according to data precision requirements. Illustratively, the timecode is 20090928.

Further, when it is determined that the classification code, time code, location code and type code of any two geographic entities are completely consistent, the sequence code of the geographic entity is determined according to the collection sequence of the geographic entity.

Among them, the sequence code is coded with 6-digit fixed-length numbers or letters. When different geographic entity classification codes, type codes, location codes and time codes are completely consistent, the entity sequence code is determined according to the entity collection sequence. Exemplarily, the sequence code has a total of 6 bits, and the value range of each sequence code is 0 to 9, a to z, and is coded from right to left. If the sequence code is less than 6 bits, the upper bits are filled with "0", such as the sequence of the Canton Tower. The code is 000001.

In step S14, a geo-entity identity document (GID) is generated according to the classification code, the time code, the sequence code, the location code and the type code. Specifically, the identification number of the geographic entity can be generated according to the sequence of the location code, the classification code, the type code, the time code, and the sequence code.

In step S15, the name information and website information of the geographic entity are acquired. It should be noted that the name information represents the name of a geographic entity, such as Canton Tower. The website information includes the identification number of the geographic entity, and an example of the website information is shown in Table 3. The URL information is the URL of the geographic entity information, and the displayed content of the corresponding geographic entity can be viewed through the URL. Among them, the displayed content of geographic entities mainly includes the names, codes, basic attributes, professional attributes, pictures, and 3D models of real-world entities.

In step S16, an identification code of a geographic entity is generated according to the identification number, the name information and the website information, and the information of the geographic entity is displayed according to the identification code. The identification code may be a two-dimensional plane identification such as a two-dimensional code or a barcode.

Further, the method further includes: acquiring attribute information of the geographic entity according to the identification code, and dynamically displaying the information of the geographic entity according to a preset display model and the attribute information. The preset display model includes a webpage template. After determining the content displayed by the geographic entity, according to the pre-configured dynamic webpage template, the webpage displays the geographic entity name, code, basic attributes, professional attributes, pictures, and 3D model of the real scene. The web page of the geographic entity can be automatically generated and updated based on the template and the GID query database for the non-confidential information of the geographic entity.

In this embodiment, a two-dimensional code is used as an example for description. According to the GID, name information and website information (url) of the geographic entity, the root node and sub-node servers established by the MA identification system issuer automatically generate the two-dimensional code of the geographic entity according to the GID and the website address. The MA identification system is my country's first independent and controllable international standard identification system with global root node management rights and code resource allocation rights, which can be used to uniquely identify any type of object globally. After the geographic entity is created, a globally unique ID (GID) is automatically generated, and a globally unique QR code is also generated synchronously. The ID and QR code are the unique identification codes of the geographic entity, which will not change with the update of the geographic entity until the demise of the geographic entity.

In specific applications, the spatial identity QR code of geographic entities should be generated using national or international standards such as QR code (ISO/IEC 18004), quick response matrix code (GB/T 18284) or Chinese letter code (GB/T 21049). .

Geographic entities have various types such as points, lines, surfaces, and volumes, and have the distinctive features of multi-granularity, multi-modality, multi-level, and carrying structured, semi-structured and unstructured diverse information. The present invention manages the location data of different types of geographic entities by establishing a multi-level spatial grid; stores geographic entity attribute data through "basic attributes + extended data", and effectively improves the organization, processing, analysis, transmission and utilization efficiency of geographic entity data , which embodies the "one-code polymorphism" feature of the new basic surveying and mapping, realizes the standardized and standardized management of geographic entities, and effectively provides more convenient surveying and mapping geographic information services for various applications.

In order to facilitate the understanding of the present invention, some preferred embodiments of the present invention will be further described below.

In an implementation manner, the location code of the geographic entity is calculated according to the geographic coordinates and spatial range of the geographic entity, which specifically includes:

S21, establishing a plane mesh model and a height mesh model including different levels;

S22, according to the geographic coordinates and the spatial extent of the geographic entity, respectively calculate the plane sub-grid and the height sub-grid to which the geographic entity belongs in the plane grid model and the height grid model;

S23, obtaining the plane subgrid code and the height subgrid code corresponding to the plane subgrid and the height subgrid;

S24: Determine the location code of the geographic entity according to the plane subgrid code, the height subgrid code, and a preset grid model level.

In step S21, establish a plane mesh model and a height mesh model including different levels, specifically including:

Project the surface of the earth in a plane, and expand the latitude and longitude to obtain a plane basic grid model;

According to a preset grid model level, quadrangular division is performed on the plane basic grid model to obtain a plane sub-grid;

Obtaining a plane mesh model including different levels according to the plane sub-mesh;

According to the spatial range from the center of the earth to the surface, establish a high-level basic grid model;

According to a preset grid model level, the height base grid model is subjected to binary division to obtain a height sub-grid;

A height grid model including different levels is obtained according to the height sub-grid.

Wherein, when coding the sub-grid, the plane sub-grid is coded according to the preset first order and the first identifier to obtain the plane sub-grid code; according to the preset second order and the second identifier, the The height sub-grid is coded to obtain the height sub-grid code.

Specifically, the Earth's surface is projected on a plane from the equator and the prime meridian, extending longitude from -180° to 180° to -256° to 256°, and latitude from -90° to 90° to -256° to 256° , forming a 512° × 512° square as a plane base mesh model. On the plane base mesh model, quadrant division is performed to form 4 plane sub-grids. Two-dimensional plane grid coding uses G0, G1, G2, and G3 to represent the southwest hemisphere, southeast hemisphere, northwest hemisphere, and northeast hemisphere, respectively. Each level of plane grid is based on the previous level of plane grid. Divide to form 4 planar sub-grids.

Further, the plane sub-grid is encoded according to the preset first order and the first identifier to obtain the plane sub-grid encoding. In this embodiment, 0, 1, 2, and 3 are used as the first identifiers, and the "Z"-shaped encoding is the first order, and the four plane sub-grids are encoded respectively. According to the preset grid model level, iteratively, continuously subdivide the grid, establish plane sub-grids of different levels, and finally obtain a plane grid model including different levels according to all the plane sub-grids. Of course, in other embodiments, other numbers, letters, etc. may also be used as the first identifier, and other coding sequences may be used as the first sequence, which will not be repeated here.

Specifically, the height basic grid model is established from the center of the earth to about 56996km on the surface, ranging from 0° to 512°, of which 1° is about 111.32km. On the height basic grid model, perform binary division to form 2 height sub-grids, use 4 and 5 as the second identifier, and code the 2 height sub-grids in the second order from low to high. According to the preset grid model level, iterating in this way, the grid is continuously subdivided, sub-grids with different levels of height are established, and finally a height grid model including different levels is obtained according to the height sub-grids.

In steps S22-S24, according to the geographic coordinates and spatial extent of the geographic entity, the plane sub-grid and the height sub-grid to which the geographic entity belongs in the plane grid model and the height grid model are respectively calculated, and then the corresponding plane is obtained. The sub-grid, the plane sub-grid encoding of the height sub-grid, the height sub-grid encoding, and then according to the plane sub-grid encoding, the height sub-grid encoding and the preset grid model level, determine The location code of the geographic entity.

Further, in this embodiment, the grid model level is set to 18, and the grid size is 250m×250m. According to the geographic coordinates and spatial extent of the geographic entity, the location of the geographic entity in the grid is determined, and the grid location coding rule of the geographic entity is established, as shown in Figure 2 below. Among them, X and H represent the position codes of geographic entities in each plane and height level grid respectively. Exemplarily, the generated geographic entity location code is G340414141535052424350404153404050515.

In this embodiment, for the establishment and storage of geographic entity data, information such as GID of each geographic entity is recorded. When establishing a database, first draw the geographic entity range, create a geographic entity, and then add the geographic entity name, geographic entity identification number (GID), classification code, location code, time code, type code, sequence code, process node, and death time. and basic attributes such as address entry. Wherein, the GID is formed by combining the location code-category code-type code-time code-sequence code. In the process of entering the professional attributes of geographic entities, the professional attributes of geographic entities are entered according to the needs of each major for the use and management of geographic entities. Taking a building entity as an example, the surveying and mapping major needs to enter the building floor, structure, unit, survey date, surveyor and other attributes, and the cultural tourism major needs to enter the attributes such as traffic, scenery features, and photos. In the process of geographic entity data storage, the geographic entity and attribute information are stored in the database, and a globally unique GID code is automatically established according to location code-category code-type code-time code-sequence code.

In the process of use, the user scans the QR code, and the root node and sub-node servers established by the MA identification system issuer parse out the GID and url, and then call the database to find the basic attributes of the geographic entity at the back end according to the geographic entity GID obtained by scanning. and professional attributes. According to the webpage template, the relevant attributes of the geographic entities returned by the backend are displayed in the webpage, and the attribute information of the geographic entities is dynamically displayed.

The present invention designs a method for displaying geographic entity information by using a dynamic web page, storing the GID, name and url of the geographic entity in a two-dimensional code, scanning the two-dimensional code to obtain the GID, and querying the geographic entity attributes, pictures, videos, For non-confidential information such as the 3D model of the real scene, through the geographic entity information returned from the background, a webpage is generated in the designed webpage template, and the relevant information of the geographic entity is dynamically displayed. An example of the webpage display is shown in Figure 3. The length of the web page is not limited, and it can not only display the numbers, characters, Chinese characters and other information stored in traditional QR codes, but also display unstructured information such as pictures, 3D models of real scenes, and panoramic images, and can fully display all attributes of geographic entities. After the geographic on-site attributes are updated, by scanning the QR code again, the content of the web page can be automatically updated to meet the management and display needs of different departments for geographic entities. Compared with traditional barcodes, two-dimensional codes can store more information and express more data types. They have the advantages of low cost, easy production, strong fault tolerance, and error correction functions. At the same time, two-dimensional codes are easy to use and spread. Features. The present invention utilizes the advantages of the two-dimensional code, and improves the query, transmission and display efficiency of geographic entity attributes.
