1. A coordinate mutual conversion module for mutually converting:

  • a mesh code for displaying a position in a combination of a block number of a block, a unit number of a unit, and a mesh number of a mesh, wherein a globe is divided into six in the east-west direction along longitudes at intervals of 60 degrees, and divided into at least three in the south-north direction along latitudes to define a plurality of numbered blocks, each of said blocks is divided into 100 in the east-west direction and. In the south-north direction, respectively, to define a plurality of numbered units substantially in a square shape, and each of said units is divided into 10n in the east-west direction and in the north-south direction, respectively, to define a plurality of numbered meshes substantially in a square shape; and

    for mutually converting respective latitudes and longitudes of new positioning system coordinates and old positioning system coordinates, and coordinate values of X, Y coordinates corresponding to the new positioning system coordinates, and the old positioning system coordinates, respectively, said coordinate mutual conversion module comprising;

    input means for entering each of the latitude/longitude and the coordinate values;

    block number selecting means for finding in which blocks each of the latitude/longitude and the coordinate values are located;

    unit number selecting means for finding in which units in the block found by said block number selecting means each of the latitude/longitude and the coordinate values are located;

    mesh number selecting means for finding in which meshes in the unit found by said unit number selecting means each of the latitude/longitude and the coordinate values are located; and

    output means for calculating and delivering the latitude/longitude, and the coordinate values corresponding to the position in the mesh code representation.
