To draw a world map of a correct land area on a plane.SOLUTION: When a world map is spread on a plane, a three-dimensional sphere is two-dimensionally represented, and distortion inevitably occurs in one or all of an area and a shape of a land, a bearing, and a distance. This method can correctly represent the land area thereof. The globe is divided into four semispheres, and an outer peripheral curve equal in length to a vertical 90-degree latitude line and a 90-degree longitude curve of an equal size horizontally dividing an equator are connected on an extension of 45 latitude, thereby representing roundness of the globe on a plan map. By equally dividing and connecting outer peripheral lines, widths become equal anywhere on the same latitude, and the widths are narrower as the longitude of the largest width on the equator becomes nearer to a pole, and become 0 at the pole. By placing coordinates of the land on a map writing only the latitude and the longitude, a world map of a correct area at any place is completed.SELECTED DRAWING: Figure 1

The present invention relates to a horizontal sundial. An acrylic glass body refracts the sunlight entering through a pinhole aperture. A scale displays the time zone (Central European Time), the date, and a world map shows the subsolar point. The refraction of light ensures that the projection of the sun's rays from a great distance is brought into a finite horizon circle. This allows the sun's movement to be tracked on the sundial year-round. The acrylic glass body is shaped like a truncated cone. This largely prevents sunlight striking the surface from the inside from falling onto the dial, brightening it, and impairing the visibility of the indicator's shadow. The sundial is calculated for a specific location. By carefully turning three adjusting screws, the dial can be rotated so that the sundial can be read with the same accuracy at other geographical locations.
