Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular map in which the surrounding environment of a point is represented in a larger size.

Conventional technology Various maps such as world maps, local maps, topographic maps, land use maps, and traffic maps have been known since ancient times, but all of them represent a certain area as a whole. When trying to know the environment, the point and the points in the vicinity thereof are only represented in small parts on the map.

Problems to be Solved by the Invention In such a map, when trying to represent the surroundings of one point in detail, there is a limit on the paper surface, and points that are a little further apart may not be displayed on the same paper surface, or the map may simply be displayed. Even if it was made large, it was not possible to fit the distant points in the north, south, east, and west into the same field of view, and it was difficult to correctly grasp the surroundings of a point in the surrounding environment.

Therefore, it is an object of the present invention to provide a map that allows a user to grasp the surrounding environment from a single point in a wide field of view.

Means for Solving the Problems In the present invention, in a circular map in which the environment surrounding a point is represented in a circle, the point is placed on the circumference, and the environment surrounding the point has the same azimuth, and the circle By expressing it in the above circle by scaling it toward the center of
The above object is achieved.

That is, in the map of the present invention, a specific point is placed on the circumference of the circle, and the map of the entire circumference of the point is shown in the circle in a larger and more detailed manner as the area near the point is larger. It is very easy to understand the environment of, and the information of the area away from the specific point gradually becomes smaller, but since it is all represented within the circle, the areas distant from north, south, east, west, and north It is possible to grasp accurately with a feeling.

It should be noted that the map of the present invention represents the environment around a point located on the circumference with 0 on the circumference, and scaled toward the center of the circle on a logarithmic scale or a uniform scale. However, it is easy to fit the whole world into a circle, especially when expressed on a logarithmic scale. If necessary, the ambient environment may be represented in a circle by combining two types of a uniform scale and a logarithmic scale, and reducing the scale.
For example, the outer circumference of a circle (that is, the area adjacent to a specific point)
Is scaled on a uniform scale, and the inside (that is, the area away from a specific point) is scaled on a logarithmic scale, so that the information of the very close area of the specific point is expressed in detail, and the relationship with the long distance is shown. You can also get a map that you can see.

On the contrary, as a map in which the information on the long distance is also shown in some detail, the outer peripheral portion of the circle may be scaled on a logarithmic scale, and the inside where the information is difficult to enter may be scaled on a uniform scale.

In the map of the present invention, a small circle may be provided in the center of the circle when it is not necessary to obtain information that has become distantly small. Good. In addition, other information such as a map description, a symbol, and a photograph may be written in this hollow portion.

Further, the map of the present invention may be used in combination with other information by utilizing a part of the circular map. For example, only the necessary orientation may be created in a fan-shaped or semi-circular map, or a logarithmic scale. It is also possible to cut out and use only the ocean part of the world map created with the scale. In addition, the surrounding environment of this point may be enlarged and displayed toward the outside of the circumference of the map that is circular in shape with one point as the outer circumference.

Next, the present invention will be described in more detail with reference to Examples.

Example 1 FIG. 1 shows three types of maps showing the surrounding environment, centering on Furano in Hokkaido. FIG. 1A shows a conventional map, while FIG. C is the map of the present invention.

Fig. 1A is a map showing the environment around Furano as a center, and the circumference is 1000 km points on a uniform scale, whereas Fig. 1B shows Furano on the circumference of a circle. Place, 100 from Furano
It is a map showing the surrounding environment in a circle, scaled by a uniform scale so that the point 0 km away is the center, and Fig. 1C shows Furano on the outer circumference of the circle, 100 from Furano.
It is a map that represents the surrounding environment in a circle with a logarithmic scale so that the point at a distance of 0 km becomes the center.

In these three types of maps, Furano, that is, a section of a certain distance from the 0 point shows the ratio of the area occupied on the map as shown in Table 1. As is clear from the results of FIG. 1 and Table 1, in the conventional map, Hokkaido is only represented in the center of the circle as shown in FIG. 1A, and the environment near Furano is represented on the map. On the other hand, in the map of the present invention, as shown in FIG.
Hokkaido can be widely represented along the circumference of a circle, and Furano can be grasped as one point in Hokkaido, and at the same time, the environment around Furano can be read from a map. Further, in FIG. 1C using the logarithmic scale, Hokkaido can be represented in an area of 70% or more of a circle, and the environment in the range of 20 kg from Furano can be represented in a large area of 55%.
The environment around Furano in Hokkaido can be recorded and recognized in detail.

Example 2 The map shown in FIG. 2 is a map of the surrounding environment centered around the Kyoto prefectural government. The Kyoto prefectural government is placed on the circumference of the circle, and the surrounding environment is scaled toward the center of the circle on a logarithmic scale. It is what is shown in. In this map, the transportation network surrounding the Kyoto Prefectural Government is revealed in its entirety, and the distance from the Kyoto Prefectural Office can be compared by the distance from the circumference on the diameter of the circle. It can be easily grasped.

Example 3 FIG. 3 is a world map centering on Narita New International Airport, where a control tower of Narita New International Airport is placed on the circumference of the circle, and the world map is shown within a circle on a logarithmic scale. Therefore, the terminal buildings and runways seen from the control tower are clearly shown along the circumference, and the relationship between each country and Narita New International Airport can be grasped with an accurate sense of distance.

In this map, only the information on Narita New International Airport is entered, but it goes without saying that traffic routes such as buses and trains and other information may also be entered.

Example 4 In FIG. 4, the control tower of Narita New International Airport is placed on the circumference like FIG. 3, and the distance from about 500 km to 10000 km from Narita New International Airport is displayed as it is, and the part following it. Is a map of the air route in the circle scaled to a uniform scale.

On this map, many air routes can be drawn in a very easy-to-understand manner, and the distance and positional relationship between Narita New International Airport and the airports of each country become clear.

Comparative Example 1 FIG. 5 is a map in which the same air route as in Example 4 (FIG. 4) is entered on the flower-shaped world map centered on Tokyo obtained in Japanese Utility Model Publication No. 60-21765.

FIG. 5 is a circular map in which one point is placed in the center contrary to the present invention. In this map, when many air routes are entered, lines overlap each other, making it difficult to determine the location of the nearby airport. In addition, since maps are separated in remote areas, it becomes difficult to compare the distance and positional relationship between Narita New International Airport and airports in each country.

Advantageous Effects of the Invention The map of the present invention can represent environmental information around a single point in greater detail in a closer manner, and can also focus on the surrounding environment within a circle, thus giving priority to the whole. You can clearly know the information that will be lost if you do so in the context of the relationship with the whole.
