Description

Description: TECHNICAL FIELD The present invention relates to a method for displaying a map showing a relatively small area.

[Conventional technology and its problems]

A map that displays residences and the like in the administrative divisions is displayed on the basis of the name of the town, with a chome, an address, a number, and the like.

However, these town names, streets, street numbers, etc., are determined according to the houses generated by the natural increase, so there is no specific regularity. There was a problem that it was difficult to search for.

On the other hand, it is theoretically possible to represent the point by latitude and longitude using rectangular coordinates, but it is a very fine number of digits, it is very inconvenient to use, and it does not fit the actual sense there were.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a map display method for displaying a specific point very easily.

[Means for solving the problem]

A map display method according to the present invention that meets the above object is to arrange road origin markers for each administrative division, provide distance circles at predetermined intervals around the road origin markers, and radially center around the road origin markers. An azimuth line is provided at a predetermined angle, and a point is displayed by the distance circle and the azimuth line.

Here, the azimuth line is preferably described on a clock scale with true north as the origin in accordance with human perception.

The road origin mark refers to an origin serving as a reference, and the present invention is also applicable to a case where a distance circle and an azimuth line are described on another transparent plate and viewed on a map.

[Action]

In the map display method according to the present invention, a road mark is arranged for each administrative section, distance circles are provided at predetermined intervals around the road mark, and a predetermined angle is set in the radial direction around the road mark. The azimuth line is provided by.

Therefore, an arbitrary point can be represented by the distance circle and the azimuth line, and by describing or arranging these points on a map, an arbitrary point can be specified in accordance with human senses.

〔Example〕

Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

Here, FIGS. 1, 2, 3, and 4 show specific examples of maps to which the map display method according to the present invention is applied.

First, a road origin mark is placed at a position at the center of an administrative division composed of individual municipalities or wards, for example, a city hall.
This road marker is preferably a stone or concrete marker having a long life, but it is not always necessary to actually place the marker, as long as it determines a reference position (origin).

Then, as shown in FIG. 1, the position of the road mark 10 is determined as in each administrative section, and concentric circles 11a, 11b, 11c. ··· are described, and a line is drawn radially in the radial direction from the position of true north as the origin, and divided into 12 equally, and the azimuth lines 12a, 12b,... Are described.

In this case, if the administrative divisions are different as shown in Fig. 1,
A road marker 10 is also set in the next administrative division, and distance circles 11a and 1
.. And the azimuth lines 12a, 12b,.

And each azimuth line 12a, 12b ... and each distance circle 11a, 11b
.., The distance from the road origin mark 10 and the azimuth described on a clock scale are described as shown in FIG.

In FIG. 2, a map showing the state of a house is created by using the method of the present invention. However, an arbitrary point is represented by a distance circle and an azimuth line, and therefore, a point is displayed regardless of a street name, a street number, and the like. be able to. In FIG. 2, the name,
Although a street name, an address, and the like are omitted, it is preferable to list them together.

FIG. 3 is an enlarged view of FIG. 2, in which a distance (for example, km) clock scale is described at the intersection of the distance circle and the azimuth line. Note that, in FIG. 2, the azimuth line is described as being divided into 60 equal parts, and in FIG.

FIG. 4 shows a map in which a specific area is enlarged using the above method, and the direction between the azimuth lines 19 and 20 is further divided into six equal parts.
The distance between the distance circles 4 (km) and 5 (km) is further divided into ten equal parts. Therefore, according to this display method, it is possible to easily display even a place away from the road origin mark 10 (the center point displayed on the map). For example, the point 14 shown in FIG. Is displayed as (4.3-19.20).

In the above embodiment, the map was displayed by directly describing the distance circle and the azimuth line on the map.However, the road original mark and the reference line at the position of, for example, true north were described on the map,
It is also possible to search or determine a specific place by superimposing a direction circle and an azimuth line described on a glass or transparent synthetic resin plate thereon.

Further, in the above-described embodiment, a conventional map is input to a computer or the like, and the position is displayed by superimposing a distance circle and an azimuth line arranged at a predetermined distance centered on the road origin mark. Is also possible.

〔The invention's effect〕

According to the method of the present invention, an arbitrary point is displayed by a distance circle and an azimuth line, so that the point can be easily searched on a map.

Even when there is no street name or address (for example, beach, mountain, wilderness, etc.), it can be easily displayed on a map.

Further, the arrangement of water pipes and gas pipes can be displayed, and the position can be easily displayed even in a rescue operation in an emergency such as a fire or water shortage, which is convenient.
