Description

A kind of to the earth surface piecemeal and carry out Methods for Coding-GPS sign
Technical field
The present invention relates to the geography information field, specifically, relate to mutual geographical location information between objects such as user, software, hardware, the block encoding method of indicating self position.
Background technology
Along with the development of modern science and technology, positioning service has obtained Preliminary Applications in the middle of daily life and work.Location technology itself is also among constantly improving and developing.But:
The first, the elements of a fix of people's cognition at present are 32 fens 33.3 seconds/north latitude, 42 degree of east longitude 111 degree 44 minutes and 33.1 seconds for example, geographic coordinate point of unique identification, but because the restriction of memory capability, and people often are difficult to the sign of remembeing that longitude and latitude is such.
The second, the distance size of paying close attention to for different people is different, for people's care of walking be unit with rice because tens meters distance difference just may cause getting lost.But for driver's care with 100 meters or kilometer be unit, tens meters distance in most of the cases need not be concerned about for the driver, but tens kilometers difference may cause getting lost.Equally for aviator's care in tens kilometers, several kilometers distances are i.e. mistake in a twinkle, but tens kilometers difference may cause danger and mistake.Several meters error may cause can't finishing of target for guided missile.Therefore the user is different to the requirement of bearing accuracy.
The 3rd, more care is the position of oneself, other people position and the contents such as target relevant with certain particular location in the middle of the daily life.But this needs an expression way easily.
Therefore the present invention is conceived to solve the people's daily life and the central station location marker problem of working, and makes the user can use whole world station location marker mode unified, that conveniently remember, conveniently use to satisfy different location needs.And this present just geographic coordinate mode institute is unapproachable.
Summary of the invention
The invention provides a kind ofly to the earth surface piecemeal and carry out Methods for Coding, be called the GPS sign, be called for short the GP coding.Use this coding method, people can remember and mutual geographical location information easily, and can satisfy the positioning requirements of different accuracy.
People's short-term memory is 5～9 the bests, so during code Design, and we select for use people to know and the character that is difficult for obscuring, adopt short as far as possible coded system that piecemeal is encoded.
Method of partition:
The GP warp: a GP warp is exactly a traditional warp, since 0 degree warp, the parallel circle is carried out 32*32*32*32*32=33, the warp of 554,432 five equilibriums is the GP warp, and all GP warps constitute a subclass of terrestrial meridian, have 33,554,432.Difference of longitude between any two adjacent GP warps is

Degree.
The GP parallel: a GP parallel is exactly a traditional parallel, from the equator, warp is carried out 32*32*32*32*16=16,777, the parallel of 216 five equilibriums is the GP parallel, and all GP parallels constitute a subclass of earth parallel, total 32*32*32*32*16+1=16, article 777,217, (wherein comprise arctic point and Geophysical South Pole).Difference of latitude between any two adjacent GP parallels is
Figure A20051007327600051
Degree.
Article 33,554,432, GP warp and 16,777,217 GP parallels are divided into 32*32*32*32*32*32*32*32*32*16=562 with earth surface, and 949,953,421,312 pieces are called the GP piece, shown in figure one.
The shape of not all GP piece all is identical with size, and the GP that only is in same GP parallel band is block-shaped identical with size.Maximum GP piece is positioned at the GP parallel band of both sides, equator, becomes the square of 1.19 meters of 1.194 meters * approximately, along with the increase of latitude, the GP piece length on two limits up and down reduces, and shape gradually becomes rectangle (trapezoidal), and area reduces, near the two poles of the earth, the GP piece is triangular in shape.Specifically be calculated as follows:
1. the terrestrial meridian circumference is 39940.67 kilometers, and what connect the two poles of the earth, north and south is the 39940.67/2=19970.335 kilometer through line length, like this, and each GP piece (19970.335*1000)/(32*32*32*32*16*)=1.190 long from south to north that mark off meter.
2. the terrestrial equator circumference is 40075.36 kilometers, long (40075.36*1000)/(32*32*32*32*32)=1.194 of the GP piece east-west direction of both sides, equator meter.Latitude is that the parallel circumference of α is a 40075.36*COS α kilometer, is positioned at the GP piece of this parallel band, east-west direction long (40075.36*1000*COS α)/(32*32*32*32*32) rice.
For example: the somewhere is at north latitude 40 degree, and the parallel circumference is 40075.36*COS40 °=30699.51 kilometers, the GP piece east-west direction of this area long (40075.36*1000*COS40 °)/(32*32*32*32*32)=0.915 meter.(X, Y) (X is a longitude, and Y is a latitude) must be positioned at a GP piece for any one geographic position G that identifies with warp, latitude of earth surface.
Regulation: for the point on the GP block boundary, the some ownership on circle, GP piece west and the south bound is in this GP piece, and boundary and northern borderline point belong to adjacent GP piece in the east.North latitude 90 degree parallels and south latitude 90 degree parallels because be condensed to two points (arctic point and Geophysical South Pole), can belong to any one adjacent GP piece in theory, and practical application is nonsensical, does not do too much regulation.
The GP piece comes unique identification by one two tuple (X ', Y '), wherein, X ' is a longitudinal GP piece coordinate, and Y ' is a latitude direction GP piece coordinate, and X ', Y ' adopt 5 32 system characters to encode respectively, 0～9 and A～Z commonly used in people's daily life selected for use in coded character, get rid of the character of obscuring easily in the audiovisual identification, be specially: the D among the B/D, the J among the G/J, I among the I/1, and 0 (letter) in 0/0 (letter), simultaneously, the regulation English alphabet adopts capitalization in formal the use.Like this, 22 English alphabets add that 10 arabic numeral just in time are 32 characters, and the coded character table is as follows:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
0 1 2 3 4 5 6 7 8 9 A B C E F G
16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
H K L M N P Q R S T U V W X Y Z
