Description

The present invention relates to a land boundary line management system, and is suitable for application to, for example, management of a land boundary line in a mountainous area.

Boundary markers such as stakes with a mark on the head that identifies the position of the boundary point are installed on the boundary line of the land. Since the registration of land is based on the boundary marker, the boundary marker is extremely important, and damage to the boundary marker, movement or removal without permission is subject to punishment. In addition to or instead of a boundary marker, targets such as trees, rivers, and mountain roads on the boundary line may be treated in the same way as the boundary marker and registered.

Conventionally, as a method of recording and managing the position information of a marker that serves as a boundary marker or a surveying point, a mobile terminal in which a non-contact IC tag is attached to the boundary marker or the marker and a GPS receiver and a non-contact IC tag reader / writer are added. The GPS receiver acquires the position information of the boundary mark or the sign, and the non-contact IC tag reader / writer records the position information on the non-contact IC tag attached to the boundary mark or the sign, if necessary. Accordingly, there is known a position information recording management method in which the position information recorded in the non-contact type IC tag is read out by a non-contact type IC tag reader / writer (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2006-292464

However, in mountainous areas, it is not easy for landowners of the land to enter the site and check the status of boundary markers and targets, so it is often not possible to check for a long period of time. Under such circumstances, in recent years, without the knowledge of the landowner or the municipality that manages this land, a person unrelated to the landowner or the staff of the municipality enters the mountainous area and sets the boundary marker of the land of the landowner. There are many damages such as moving or removing it without permission, and in some cases damaging it. Since it is not easy to find the movement of the boundary marker, the fact is that landowners and municipalities cannot take any measures, which is a serious problem.

Further, in the position information management recording method described in Patent Document 1, not only it is necessary to attach a non-contact type IC tag to each boundary marker or sign, but also reading and writing by a non-contact type IC tag reader / writer is required. It takes time and cost.

Therefore, the problem to be solved by the present invention is that the boundary line of land such as a mountainous area can be easily created and managed as a database at low cost, and the boundary marker or target is arbitrarily moved or removed, or a disaster occurs. It is to provide a land boundary line management system that can easily find a change in the position of a boundary marker or a target based on the database when it is moved due to such reasons.

In order to solve the above problems, the present invention
A positioning signal receiver that receives a positioning signal from a positioning satellite and is detachably attached to a boundary marker installed on the boundary line of the land to be managed and / or a target on the boundary line.
A computer in which the position information of the boundary marker or target acquired from the positioning signal received by the positioning signal receiver is transmitted and the position information is input to the map of the area including the land.
It is a land boundary management system with.

In the present invention, typically, a positioning signal is received with a positioning signal receiver attached to a boundary marker or a target, and the position information of the boundary marker or the target is acquired from the positioning signal to obtain the position information. Is transmitted to a computer via a communication device, the location information is input to the map on the computer, the map where the location information is input and the boundary line of the land is defined is stored in the server, and a database is created. If the boundary line of the land is changed due to the partial transfer of the land, etc., the positioning signal is received with the positioning signal receiver attached to the boundary marker or target installed on the boundary line after the change. , Acquires the position information of the boundary marker or the target object from the positioning signal, transmits the position information to the computer via the communication device, inputs the position information to the map on the computer, and the position information is input and changed. The map defined by the later boundary line is stored in the server together with the date of the change of the boundary line and stored in a database. Also, typically, when accumulating a map demarcated by a land boundary on a server, the land owner, the sale price of the land, and the sale price of the land in the vicinity of the land at the time when the delimiter of the land is demarcated are stored in the server. At least one of them, if necessary, other information is associated with the land and accumulated, and a database is created. Also, typically, if there is a change in the landowner of the land, the sale price of the land and the sale price of the land in the vicinity of the land after the boundary line of the land is demarcated, the landowner or the sale price after the change, If necessary, other information is also associated with the land and accumulated, and a database is created. The land can be basically any land, but is typically mountainous land. Boundary markers include concrete piles, stone piles, plastic piles, and various conventionally known markers such as metal markers and metal studs, but any of them may be used. The head of the boundary marker is marked with a circle, the tip of an arrow, the center point of the cross mark, etc. as a sign to specify the position of the boundary point. The target may be basically anything other than a boundary marker on the boundary line of the land, but specifically, for example, a tree, a river, a mountain road, or the like. In this case, the position of the positioning signal receiver is the root of the tree, the branch from the trunk, etc., the bank of the river in the river, the top of the bridge if there is a bridge, the center or the end of the road in the mountain road. However, it is not limited to this.

Positioning satellites are preferably quasi-zenith satellites (MICHIBIKI) launched in Japan, but include GPS satellites in the narrow sense launched in the United States and similar GPS satellites launched in countries other than the United States. According to the satellite positioning system using the quasi-zenith satellite (MICHIBIKI), it is possible to acquire the position information with an accuracy of several cm.

According to the present invention, it is possible to acquire the position information of the boundary marker or the target by attaching the positioning signal receiver to the boundary marker or the target of the land such as a mountainous area and receiving the positioning signal by the satellite positioning system. You can easily create a map of the land on a computer by using the location information obtained in this way and referring to the information on the boundary line of the land held by the municipality that manages the land as needed. Therefore, it is possible to easily create a database of the boundaries of the land at low cost. For this reason, the staff of the municipalities that manage the land regularly or irregularly acquire the position information of the boundary marker or target on the boundary line of the land and confirm the boundary line, so that the land is stored in a database. By collating with the boundary line of, if the boundary marker or target is moved by itself or moved due to a disaster or the like, it can be found immediately.

<One embodiment>
[Land boundary management system]
FIG. 1 shows the overall configuration of a land boundary management system according to an embodiment.

As shown in FIG. 1, this land boundary line management system includes a positioning signal receiver 20 for receiving a positioning signal from a positioning satellite 10 of a satellite positioning system, and a computer 30 for management. The positioning satellite 10 is a quasi-zenith satellite Michibiki or a conventional GPS satellite, but the quasi-zenith satellite Michibiki is preferably used. The positioning signal receiver 20 is detachably attached to a boundary marker installed at the boundary line of the land to be managed and / or a target on the boundary line. One or more positioning signal receivers 20 are used. The communication device 40 is integrated with the positioning signal receiver 20, or is connected by a cable or the like. To the computer 30, the position information of the boundary marker or the target object acquired from the positioning signal received by the positioning signal receiver 20 is transmitted from the communication device 40 by radio, the Internet, or the like. The computer 30 has a database of boundaries of each land in the area managed by the municipality, etc., which is obtained in advance as described later, in the server, and a display connected to the computer 30 by accessing this database. The border of the land can be displayed on the screen (not shown). The computer 30 also has a map information database of the area including the land to be managed on the server, downloads the map information database via the Internet, or accesses the map information database stored in the cloud server or the like. Based on this map information database, a map of the land can be displayed on the screen of the display connected to the computer 30. As the map information database, in Japan, for example, the GSI Maps of the Geographical Survey Institute of the Ministry of Land, Infrastructure, Transport and Tourism can be used. The computer 30 is arranged in, for example, a department in charge of real estate registration in a government building such as a municipality, but is not limited to this.

[How to use the land boundary management system]
First, a method of creating a database of the boundary lines of each land in the area managed by municipalities, etc. will be described using this land boundary line management system.

Now, as an example of the land for which the boundary line is managed, consider the land 100 in the mountainous area as shown in FIG. Here, the land 100 has a rectangular shape, but is not limited to this. There is a marker or target 110 on the boundary 101 of the land 100, in this case at the four corners of the rectangle. FIG. 3A shows a boundary marker 111 as an example of the boundary marker or the target object 110. The center point of the sign of the cross 112 attached to the head of the boundary marker 111 is the boundary point. FIG. 4A shows a tree 113 standing on a boundary line 101 of land 100 as another example of a boundary marker or target 110.

The positioning signal receiver 20 is detachably attached to the boundary marker or the target 110. For example, when the positioning signal receiver 20 is attached to the boundary marker 111 shown in FIG. 3A, as shown in FIG. 3B, the center of the positioning signal receiver 20 and the center point of the cross mark 112 are attached to the head of the boundary marker 111. The positioning signal receiver 20 is placed so as to be substantially in agreement with. In FIG. 3B, the planar shape of the positioning signal receiver 20 is circular as an example, but the planar shape or the like of the positioning signal receiver 20 does not matter. When the communication device 40 is integrated with the positioning signal receiver 20, the positioning signal receiver 20 and the communication device 40 are placed on the head of the boundary marker 111, and the communication device 40 is connected to the positioning signal receiver 20 by a cable or the like. If so, the communication device 40 is placed on the ground. If necessary, an adhesive sticker that can be easily peeled off may be attached to the head of the boundary marker 111, and the positioning signal receiver 20, the positioning signal receiver 20, and the communication device 40 may be attached onto the adhesive sticker. .. When the positioning signal receiver 20 is attached to the tree 113 shown in FIG. 4A, the positioning signal receiver 20 is placed on the root of the tree 113 shown in FIG. 4B, a branch from the trunk of the tree 113, or the like. When the communication device 40 is integrated with the positioning signal receiver 10, the positioning signal receiver 10 and the communication device 40 are placed on the root of the tree 113, a branch from the trunk of the tree 113, or the like, and mounted on the positioning signal receiver 20. When the communication device 40 is connected by a cable or the like, the communication device 40 is placed on the root of the tree 113 or on the ground away from the root. If necessary, an adhesive sticker that can be easily peeled off may be attached to the root or branch of the tree 113, and the positioning signal receiver 20, the positioning signal receiver 20, and the communication device 40 may be attached onto the adhesive sticker. ..

Next, the positioning signal receiver 20 is turned on (as turned on) to receive a positioning signal from the positioning satellite 10, and the position information of the boundary marker or the target 110 is acquired. The power of the communication device 40 is turned on by turning on the power of the positioning signal receiver 20, or the power of the communication device 40 is turned on independently of the positioning signal receiver 20. The position information of the boundary marker or the target 110 acquired in this way is transmitted by the communication device 40 to the computer 30 of the management center (for example, the department having jurisdiction over the real estate registration of a municipality or the like) via wireless or the Internet. A similar operation is performed on all the marker or target 110 on the boundary 101 of the land 100. As a result, the position information of all the boundary markers or the targets 110 on the boundary line 101 of the land 100 is transmitted to the computer 30.

On the display connected to the computer 30, the land 100 displays a map of the area where the land 100 is located (for example, a map of the Geographical Survey Institute created by the Geographical Survey Institute of the Ministry of Land, Infrastructure, Transport and Tourism) stored in the database or downloaded via the Internet. Display at a clearly recognizable scale. FIG. 5 shows an example of a map displayed on the display. As shown in FIG. 6, on the map thus displayed on the display, a boundary marker or a target based on the position information of all the boundary markers or the target 110 on the boundary line 101 of the land 100 acquired as described above. A mark 130 indicating an object 110 is attached. The mark 130 may be of any shape, but is, for example, ◯ or ×, and is indicated by ◯ in FIG. Then, a line segment connecting these marks 130 is drawn. The line segments thus drawn correspond to the boundary line 101, and the area surrounded by these line segments indicates the land 100. The map defined by the boundary line 101 in this way is stored in the server and stored in a database. The land 100 defined by the boundary line 101 in this way basically coincides with the land 100 registered in the real estate register owned by the municipality or the like. When creating a database of the map defined by the boundary line 101, of the land owner of the land 100, the selling price of the land 100, and the selling price of the land in the vicinity of the land 100 when the boundary line 101 of the land 100 is defined. At least one is associated with the land 100 and stored in the server to create a database. If there is a subsequent change in the land owner of the land 100, the sale price of the land 100, and the sale price of the land in the vicinity of the land 100, the land owner after the change, the sale price of the land 100, and the land in the vicinity of the land 100 are changed. The selling price of the land is also associated with the land 100 and stored in the server to create a database.

Since the outline of the land 100 has a complicated shape, if it is difficult to define the boundary line 101 only by the position information of all the boundary markers or the target 110 on the boundary line 101 of the land 100, the computer 30 to the municipality, etc. The real estate registry database owned by the company is accessed, and the outline of the land 100 on the registry obtained by accessing the database is displayed on the map displayed on the display at the same scale. The boundary line 101 is defined by using the contour of the registered land 100 thus displayed in addition to the position information of all the boundary markers or the target 110 on the boundary line 101 of the land 100.

For example, if there is a change in the boundary line 101 of the land 100 as a result of the sale of a part of the land 100, positioning is performed on the boundary mark or the target 110 on the changed boundary line 101 in the same manner as described above. The signal receiver 20 is attached to receive the positioning signal, the position information of the boundary marker or the target 110 is acquired, and this position information is transmitted to the computer 30 via the communication device 40, and is displayed on the display on the computer 30. These position information is input to the map, and the map defined by the changed boundary line 101 after the position information is input is stored in the server together with the date of change of the boundary line 101 and stored in a database.

Next, a case where the boundary marker or the target 110 on the boundary line 101 of the land 100 moves to a position different from the position on the database will be described without the knowledge of the landowner, the municipality, or the like.

Consider the case where the staff of a municipality, etc. patrols the area managed regularly or irregularly and confirms the boundary line of the land owned by the owner of each place. When confirming the boundary line 101 of the land 100, the positioning signal receiver 20 is attached to the boundary marker or target 110 on the boundary line 101 to receive the positioning signal as described above, and the boundary marker or target 110 is confirmed. The position information of the above is acquired and this position information is transmitted to the computer 30 via the communication device 40, and these position information are input to the map displayed on the display in the computer 30, and thus the position information is input and the boundary line is input. The map defined by 101 is displayed on the display. Next, the boundary line 101 of the land 100 stored in the database is read out and superimposed on the map defined by the boundary line 101, and both are collated. As a result of collation, if they match, it can be determined that the boundary marker or the target 110 has not changed from the position on the database. On the other hand, as a result of collation, if they do not match, it can be seen that the boundary marker or the target 110 has moved to a different position from the database for some reason. As an example, FIG. 7 shows a case where two boundary markers or targets 110 at both ends of one long side of land 100 have moved inward. In this way, when it is found that the boundary marker or the target object 110 has moved from the position on the database, the staff of the municipality or the like returns the boundary marker or the target object 110 to the position at the time of registration. In this way, the boundary line 101 of the land 100 can be matched with the boundary line on the database.

As described above, according to this embodiment, the boundary marker or the boundary marker by attaching the positioning signal receiver 20 to the boundary marker or the target 110 of the land 100 in the mountainous area and receiving the positioning signal by the satellite positioning system. The position information of the target object 110 can be acquired. Then, using the location information acquired in this way, the map of the land 100 can be easily displayed on the computer 30 by referring to the information on the boundary line of the land held by the municipality or the like that manages the land as needed. Can be created. Therefore, it is possible to easily create a database of the boundary line 101 of the land 100 at low cost. Then, the staff of the municipality or the like that manages the land periodically or irregularly acquires the position information of the boundary marker or the target 110 on the boundary line 101 of the land 100 and confirms the boundary line 101 to the database. By collating with the boundary line 101 of the converted land 100, if the boundary marker or the target 110 is moved by itself or moved due to a disaster or the like, it can be found immediately. Therefore, the boundary marker or the target 110 can be returned to the position on the database. This land boundary management system is extremely suitable for supplementing the real estate registry owned by municipalities.

Although one embodiment of the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and various modifications based on the technical idea of the present invention are possible.

For example, the numerical values, configurations, structures, shapes and the like given in the above-described embodiment are merely examples, and numerical values, configurations, structures, shapes and the like different from these may be used as necessary.

Further, in the above-described embodiment, the land 100 in the mountainous area is considered, but the land is not limited to this, and basically any land may be used.
