PROBLEM TO BE SOLVED: To provide a transparent mesh sheet which can be used for a map of any scale having positive composition without changing a square, on which first, it is necessary to draw vertical parallel lines at 10cm intervals in order to set the transparent mesh sheet on the map; next, by receiving GPS signals at a mountain hut, station, bridge or the like whose geographical places are known on the map to adopt the point as a reference point A, putting a point mark to that place and moving to a point B; then the direction and distance of the movement from the point A to the point B can be obtained by calculation; and the position of the point B can be confirmed with the squares by superimposing the transparent mesh sheet on the point A. SOLUTION: In the case that a moving range is known, a map as shown in Figure can be obtained, by copying the map with the mesh section put on the map, and the transparent mesh sheet is applicable to a public map, on the basis of a mountain hut or the like. When the numerical value becomes larger than the transparent mesh sheet, it is necessary merely to move it, while increasing new points as A points. Although the transparent mesh sheet permits confirmation within a range of 4km by 3km for size A3, in a 1/10,000 scale map, but production with a larger size, the entirety can be confirmed.
