When the sub-grids are coded, coding the plane sub-grids according to a preset first sequence and a first identifier to obtain plane sub-grid codes; and coding the height sub-grids according to a preset second sequence and a second identifier to obtain height sub-grid codes.
Specifically, the surface of the earth is subjected to planar projection from the equator and the meridian of the beginning, the longitude is extended from-180 degrees to-256 degrees, the latitude is extended from-90 degrees to-256 degrees to form a square of 512 degrees multiplied by 512 degrees, and the square is used as a planar basic grid model. And performing four-fork subdivision on the plane basic grid model to form 4 plane sub-grids. The two-dimensional plane grid codes respectively represent a southwest hemisphere, a southeast hemisphere, a northwest hemisphere and a northeast hemisphere by G0, G1, G2 and G3, and each level of plane grid is divided according to a quadtree on the basis of an upper level of plane grid to form 4 plane sub-grids.
And further, coding the plane sub-grids according to a preset first sequence and a first identifier to obtain the plane sub-grid codes. In this embodiment, 0, 1, 2, and 3 are used as the first identifier, and the 4 plane sub-grids are encoded in the first order in the zigzag manner. And according to the preset mesh model level, iterating in the above way, continuously subdividing the mesh, establishing plane sub-meshes with different levels, and finally obtaining the plane mesh model comprising different levels according to all the plane sub-meshes. Of course, in other embodiments, other numbers, letters, and the like may also be used as the first identifier, and other coding sequences may also be used as the first sequence, which is not described herein again.

Further, in the present embodiment, the mesh model hierarchy is set to 18 levels, and the mesh size is 250mx 250m. According to the geographic coordinates and the spatial range of the geographic entity, the position of the geographic entity in the grid is determined, and a grid position coding rule of the geographic entity is established, as shown in the following figure 2. Wherein, X and H respectively represent the position codes of the geographic entities in each plane and height level grid. Illustratively, the generated geo-entity location code is G340414153505242434041534040404050515.
In this embodiment, a database is built and put in storage for the geographic entity data, and information such as GID of each geographic entity is recorded.

Wherein, the GID is formed by combining a position code, a classification code, a type code, a time code and a sequence code. And in the process of inputting the professional attributes of the geographic entities, inputting the professional attributes of the geographic entities according to the requirements of each professional for using and managing the geographic entities. Taking a building entity as an example, the surveying and mapping profession needs to input attributes such as building floors, structures, units where the building exists, measuring dates and measuring staff, and the literary and travel profession needs to input attributes such as traffic, scenery characteristics and photos. And in the process of warehousing the geographic entity data, storing the geographic entity and the attribute information into a database, and automatically establishing a globally unique GID (group identity) code according to the position code, the classification code, the type code, the time code and the sequence code.
In the using process, a user scans the two-dimensional code, the root node and the child node server established by the MA identification system issuing organization analyze the GID and the url, then the database is called, and the basic attribute and the professional attribute of the geographic entity are searched at the back end according to the geographic entity GID obtained by scanning. And displaying the related attributes of the geographic entity returned by the back end in the webpage according to the webpage template, and dynamically displaying the attribute information of the geographic entity.
