Description
Technical Field
The invention relates to a protocol system construction method of a geospatial grid domain name.
Background
The traditional method in the geographic domain name system cannot realize data registration based on coding based on longitude and latitude position identification, and the problem is that space-time data storage is disordered, mutual matching efficiency is low, and interaction and sharing are difficult. GeoWeb and what3Words construct a coding, domain name and space information management and release system based on a global discrete grid, solve the problems of position identification and space information management and release, provide a reference idea for sharing and fusing 'position, object and information' under the condition of big data, but only solve a part of the problems. Specifically, geoWeb solves the domain name conversion problem, but mainly aims at professional space information, and does not solve the problem of conversion of ubiquitous location, objects and information under the condition of big data, and particularly does not solve the problem of unification of information ID and location code. The what3Words only takes the grid coding as the medium, solves the coding conversion problem between the abstract position semantics of longitude and latitude and the near natural language, and does not relate to the universal position conversion problem or the data organization management and release problem under the condition of big data. The what3word system is just a position coding system, and the problem of position is not only solved by the universal position information interoperation.
A Protocol (Protocol) is a series of steps or rules that two or more computer communication parties take and commonly follow in order to accomplish a particular task. This definition covers three layers of meaning, namely protocol procedure ordering, protocol co-participation and protocol completions. Protocol process order refers to an orderly process throughout the protocol, each step must be executed in turn, and when the previous step is not completed, the steps following the protocol are not executable. By co-participation in a protocol is meant that the participants of the protocol are made up of at least two, and when a person can accomplish the task by performing this step, then this step does not make up the protocol. Protocol perforability means that execution of the protocol must be able to complete a specified task, and if no task is completed, this no operation constitutes a protocol. The protocol hierarchy is often defined in several levels, with the purpose that changes in the protocol of one level do not affect the protocols of the other level.

The invention relates to a method for constructing a protocol system of a domain name of a geospatial grid, wherein the constructed protocol system of the domain name model of the geospatial grid is divided into a subdivision layer protocol, a correlation layer protocol, a management layer protocol and an application layer protocol.
1. Split layer protocol
The subdivision layer protocol is used as the bottommost protocol in the geospatial mesh domain name protocol, and is mainly used for the mesh subdivision expression and the mesh coding method of the universal position information under the GeoSOT geospatial subdivision mesh and GeoSOT-3D geospatial subdivision mesh reference frame. The subdivision layer protocol comprises a grid subdivision sub-protocol and a grid coding sub-protocol.
1.1 mesh subdivision sub-protocol
The meshing sub-protocol is a meshing subdivision representation for geospatial locations.
1.2 trellis encoding sub-protocol
The regional domain name codes are GeoSOT binary one-dimensional codes, and the exclusive domain name codes are GeoSOT-3D binary one-dimensional codes. GeoSOT-3D binary one-dimensional coding is a coding method for separately coding three dimensions of longitude dimension, latitude dimension and altitude dimension. The GeoSOT binary one-dimensional code does not need to encode the height dimension, and the longitude and latitude dimension code is the same as the GeoSOT-3D code and is not repeated.
Longitude and latitude dimension binary one-dimensional codes are more efficient in calculating inclusion relationships between codes. Assuming that the universal position information positioning point P (x, y, z) in the existing geospatial is longitude coordinate value, latitude coordinate value and altitude coordinate value of the P point respectively, satisfying x epsilon [ -180 degrees, 180 degrees ] ], y epsilon [ -90 degrees, 90 degrees ] ], z epsilon [0,50000000m ], and carrying out GeoSOT-3D binary three-dimensional coding on the P point under the nth three-dimensional grid subdivision level, specific coding assignment formulas of the GeoSOT-3D binary longitude dimension, latitude dimension and altitude dimension of the P point are respectively as follows.
The GeoSOT-3D binary longitude dimensional coding formula is as follows. Wherein GeoSOT 3D _Code(x) n And the longitude dimension code value of the three-dimensional grid corresponding to x is shown in the nth subdivision level. For example GeoSOT 3D _Code(x) 9 The three-dimensional grid longitude-dimension code value corresponding to x is shown at the 9 th subdivision level.
The GeoSOT-3D binary latitude dimension coding formula is as follows. Wherein GeoSOT 3D _Code(y) n And representing the three-dimensional grid latitude dimension code value corresponding to y under the nth subdivision level. For example GeoSOT 3D _Code(y) 9 And the three-dimensional grid latitude dimension code value corresponding to y under the 9 th subdivision level is shown.
The GeoSOT-3D binary height dimension coding formula is as follows. Wherein GeoSOT 3D _Code(z) n And the three-dimensional grid height dimension code value corresponding to z is represented under the nth subdivision level.
Thus, geoSOT-3D binary three-dimensional encoded GeoSOT at a global position information anchor point P (x, y, z) in the earth space 3D _Code(x,y,z) n Can be expressed as
(GeoSOT 3D _Code(x) n ,GeoSOT 3D _Code(y) n ,GeoSOT 3D _Code(z) n )。
So that the corresponding GeoSOT-3D binary one-dimensional code is represented as follows.
2. Management layer protocol

The metadata of the ubiquitous location information comprises country codes, shipping enterprise codes, article attribute codes and the like in the universal shipping address codes.
Defining num_of_column () as a function of the number of columns (columns) in the get-specified value (value), then there are n 1 =num_of_column (value_1) and n 2 =num_of_column (value_2). Table 1 is the grid organization protocol specification for the geospatial grid domain name index large table.
TABLE 1 grid organization protocol Specification for a large table of geospatial grid Domain names index
2.2 Domain name mapping sub-protocol for geospatial grid
The section expands and introduces the domain name mapping of the GeoSOT-3D geospatial grid, and the GeoSOT does not need to map the height dimension, and is not repeated. According to the GeoSOT-3D binary three-dimensional coding, the GeoSOT-3D binary one-dimensional grid coding and domain name identification expression mapping relation function of the earth space is as follows
MF i ＝f(GeoSOT 3D _Code i ,RegionName i ),0≤i≤32
According to the octree subdivision Z-order coding of the GeoSOT-3D geospatial stereoscopic subdivision grid, the mapping relationship between the GeoSOT-3D grid coding and the geospatial grid domain name can have the subdivision relationship, namely, the mapping relationship of eight sub-grids with the grid subdivision of the next level is established.
In the followingAnd->The domain name code mapping relation of grids from small longitude to large longitude and from low latitude to high in the low-altitude dimension is respectively represented.
In the followingAnd->The domain name code mapping relation of grids from small longitude to large longitude and from low latitude to high latitude in the high-altitude dimension is respectively shown.
