1. a geographic position coding method, is characterized in that, comprising:

  • Obtain geographic position, wherein, described geographic position comprises longitude and latitude;

    Described longitude is encoded to the scale-of-two of n-bit, wherein, the scale-of-two of described n-bit comprises sign field and data segment, described data segment comprises the first data segment and the second data segment, by the symbolic coding of described longitude to described sign field, by described longitude absolute encoder to described data segment, wherein, described first data segment represents the integral part of described longitude absolute value, and described second data segment represents the fraction part of described longitude absolute value, n be greater than 9 integer;

    Described latitude is encoded to the scale-of-two of described n-bit, by the symbolic coding of described latitude to described sign field, by described latitude absolute encoder to described data segment;

    AndCoding schedule according to presetting carries out string encoding to the scale-of-two longitude of described n-bit and the scale-of-two latitude of described n-bit, obtains position encoded.
