Abstract

The invention discloses a method for representing a spatial geographical position with a group of simple codes. In the invention, any designated area is divided, and each sub-area is coded, wherein the area can be divided multiple times; then a group of codes are formed for representing the spatial position of a certain area; and the more the dividing times is, the higher the precision is. The position can be a relative geographical position or absolute geographical position. Compared with the geographical position information represented by the existing GPS (Global Positioning System), the geographical position codes are simple and easy to remember and can achieve any precision. The geographical position codes can be used for positioning an object, serving as an address and the like.

Description

A kind of method of utilizing coding to come the representation space geographic position

Technical field

The invention belongs to the geography information field, it is characterized in that adopting the locus in one group of a certain zone of simple coded representation.

Background technology

In recent years, Chinese GPS location technology and automobile navigation technology have obtained develop rapidly, and people feel that more and more navigation brings very big facility to life, work etc.In the navigation industry the most the electronic chart of core also obtained people's understanding, study and grasp.People to requirement also more and more higher.Because China is vast in territory, populous, life relevant with electronic chart and industrial plants (POI) quantity is thousands of, and for how to represent these POI on electronic chart, what we relied on is its spatial geographical locations information.The current GPS space orientation technique that we adopt is to represent a spatial geographical locations with a pair of numeral.

The inventor finds that there is following shortcoming at least in existing position method for expressing in realizing process of the present invention: there is the shortcoming that is difficult to remember in existing space position method for expressing; There is the shortcoming that is difficult to obtain in the existing space positional information; The existing space positional information is represented the shortcoming that method exists high precision to be difficult to obtain.

Summary of the invention

The present invention proposes a kind of method of utilizing coding to come the representation space geographic position, utilization is carried out several times to a certain zone and is cut apart then, and each subregion after cutting apart encoded, thereby the spatial geographical locations of representing described zone that obtains a group coding and use.This coding is easy to obtain, is easy to memory and can reaches precision arbitrarily.

Technical scheme of the present invention is achieved in that

A kind of method of utilizing coding to come the representation space geographic position comprises: specify a zone, cut apart by the several rows columns in the zone, then the subregion after cutting apart is encoded, can carry out repeated segmentation, till meeting the requirements of precision.

Described appointed area, be this coding representative the absolute position, space start at the zone.

Cut apart in the described zone, be meant the zone of appointment is cut apart by some line numbers, columns, obtain the subregion of refinement in the appointed area, the spatial dimension of each subregion will be dwindled.Repeated segmentation will cause the spatial dimension of each subregion more and more littler.

Described coding method can be carried out by ranks number coding each subregion of cutting apart, or by serial number coding from top to bottom, or the sequential encoding of ecto-entad etc., and all codes of encoding are numeral, Chinese character, or other Languages is not done qualification.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiment that obtained under the creative work prerequisite.

Step 1: obtain earlier and comprise a nationwide zone, (N72.75 °, E-13.25 °), (N140.5 °, E54.5 °).

Step 2: be defined in the coding of implementing in the Chinese scope and be divided into five joint codes, national code-region code: subcode 1: subcode 2-extra-code, with reference to accompanying drawing 2.Be connected with "-" between national code and region code and between subcode 2 and extra-code, be connected with ": " between region code and subcode 1 and subcode 1 and the subcode 2.Here name this coding name to be called GIMCODE, below will use the GIMCODE representative.

1, national code (CNRY CODE) is being represented a zone that can comprise field, the whole of China territory.With two English alphabet signs, identical with the country code of Internet Standard.The national code of China is CN, can omit when only using at home.As: the GIMCODE of the rostrum of Tian An Men is CN-2143:3147:8439, and brevity code is: 2143:3147:8439.

2, region code (CITY CODE): the whole of China's domain is divided into 99 * 99, and a Regional Representative wherein about 3,000 square kilometres zone;

3, subcode 1 (BLOCK CODE): CITY CODE is subdivided into 99 * 99, and one of them Regional Representative about 24.5 square kilometres zone;

4, subcode 2 (UNIT CODE): BLOCK CODE is subdivided into 99 * 99, and one of them Regional Representative the zone of about 5 * 5 square metres of sizes;

5, extra-code (SUB CODE): be can a self-defining coding.When GIMCODE three joint sign indicating number navigates to inside such as a mansion, university when containing a lot of sub-facility situation, antithetical phrase facility refinement timesharing is used if desired.For example can or press the sequence number ordering by floor, number, be that all sub-facilities distribute unique GIMCODE codes one by one.

Step 3: the coding method principle, the numbering standard of the every joint code of GIMCODE: from top to bottom, be numbered from left to right, the numbering code uses arabic numeral to represent, and each joint lowest number is 1, and maximum numbering is 9801.

Step 4: the Region Segmentation technology that following introduction is concrete.

1, the zone of whole China is carried out by row 99, row 99 cut, and then subregion are cut in 9801 after the cutting and encode by mentioned above principle, obtain region code (A).

2, each rapid subregion of previous step is carried out by row 99 again, row 99 cut, encode, and obtain subcode 1 (B).

3, the zone of character code 1 representative is carried out by row 99 again, row 99 cut, encode, and obtain subcode 2 (C).

4, character code 2 is carried out said method, both can obtain extra-code (D).

Obtain one group of code: CN-A:B:C-D like this, promptly representing the locus in a certain zone.
