[0006] The objective of this disclosure is to provide a technology for instantly detecting surrounding areas using a computer. [Means for solving the problem]

[Effects of the Invention]

[0008] According to this disclosure, a technology can be provided for instantly detecting surrounding areas using a computer. [Brief explanation of the drawing]

[Figure 2] Figure 2 is a block diagram showing the hardware configuration of an information processing device according to one embodiment of the present disclosure. [Figure 3] Figure 3 is a block diagram showing the functional configuration of an information processing device according to one embodiment of the present disclosure. [Figure 4] Figure 4 is a flowchart showing the map information display process according to one embodiment of the present disclosure. [Modes for carrying out the invention]

[0010] Embodiments of this disclosure will be described below with reference to the drawings.

[0011] In the following embodiment, an information processing device is disclosed that detects and displays surrounding areas from map information.

[0012] [overview] An information processing device 100 according to one embodiment of this disclosure detects land that does not adjoin a public road (enclosed land) from map information and displays the detected land as enclosed land on the map information. For example, in the example shown in Figure 1, land parcels X1 to X8 face public roads, but land parcel X9 does not face any public road. Such land parcel X9 that does not face a public road is called enclosed land. Typically, residents of enclosed land have no choice but to pass through the land of other owners in order to access a public road. Due to this inconvenience, enclosed land tends to be valued lower than surrounding land that faces a public road.

[0013] On the other hand, if ownership of such surrounding land is acquired by the owner of the land adjacent to the public road bordering the surrounding land, the two parcels of land can be combined into a single parcel through, for example, a land consolidation registration, thereby resolving the surrounding land situation. Generally, the assessed value of the combined land may be increased by the amount that was previously undervalued as surrounding land.

[0014] However, it has been difficult to identify whether a piece of land is surrounded by other properties using only conventional real estate registration information. Furthermore, even when using a Geographic Information System (GIS), technologies for detecting surrounding properties based on geographic information provided by the GIS have not been considered until now.

[0015] In the following embodiments, for example, when a certain geographical area is specified by a user in the map information displayed on the display, the information processing apparatus 100 acquires land polygons indicating each piece of land included in the specified geographical area, detects an enclosed area not adjacent to a public road based on the topology data of the acquired land polygons, and displays the detected enclosed area on the map information. Here, the topology data is typically data that can be associated with each land polygon and indicates the spatial relationship (e.g., connection, adjacency, inclusion, etc.) with other polygons.

[0016] According to such an information processing apparatus 100, a user can easily confirm the enclosed area existing in the geographical area by specifying a desired geographical area in the map information displayed on the display.

[0017] Here, the information processing apparatus 100 may have, for example, a hardware configuration as shown in FIG. 2. That is, the information processing apparatus 100 includes a storage device 101, a memory device 102, a processor 103, and a communication device 104 that are interconnected via a bus B.

[0018] Programs and / or data for realizing various functions and processes in the information processing apparatus 100 are downloaded from an external device and / or network to the storage device 101 or the memory device 102 via the communication device 104.

[0019] The storage device 101 is realized by a non-volatile memory or the like and stores installed or downloaded programs or data (e.g., files, etc.).

[0020] The memory device 102 is realized by a random access memory, a static memory, etc. When a program or an instruction is activated, it reads and stores a program, an instruction, data, etc. from the storage device 101. The storage device 101, the memory device 102, and the removable storage medium may be collectively referred to as a non-transitory storage medium.

[0021] The processor 103 may be realized by one or more CPUs (Central Processing Units), GPUs (Graphics Processing Units), processing circuits, etc. that can be composed of one or more processor cores. It executes various functions and processes of the information processing device 100 according to data such as programs, instructions, and parameters necessary to execute the programs or instructions stored in the memory device 102.

[0022] The communication device 104 is realized by various communication circuits that execute wired and / or wireless communication processing with communication networks such as external devices, the Internet, LAN (Local Area Network), and cellular networks.

[0023] However, the above hardware configuration is merely an example, and the information processing device 100 according to the present disclosure may be realized by any other appropriate hardware configuration.

[0024] [Information Processing Device] Next, the information processing device 100 according to an embodiment of the present disclosure will be described. FIG. 3 is a block diagram showing the functional configuration of the information processing device 100 according to an embodiment of the present disclosure. As shown in FIG. 3, the information processing device 100 includes an acquisition unit 110, a detection unit 120, and a display unit 130. Each functional unit of the acquisition unit 110, the detection unit 120, and the display unit 130 may be realized by the processor 103 of the information processing device 100 executing a program stored in the memory device 102.

[0025] The acquisition unit 110 acquires land polygons representing each plot of land on the map information. For example, if a user specifies a desired geographic area on map information displayed on a display provided by a geographic information system, the acquisition unit 110 acquires various polygons, including land polygons for each plot of land included in the specified geographic area.

[0026] Various types of polygons, including land polygons, are available from government agencies such as the relevant government ministries, local authorities, and other public institutions, and can be used on geographic information systems. Typically, land polygons may include geographic data indicating the location and shape of the land, such as latitude and longitude; attribute data such as the land's use, owner, place name, and area; and topology data indicating spatial relationships with other polygons (e.g., connection, adjacency, inclusion, etc.). In other words, the topology data of a land polygon indicates the spatial relationships between polygons on the map information.

[0027] The acquisition unit 110 provides the acquired land polygons to the detection unit 120.

[0028] The detection unit 120 detects surrounding land that does not adjoin public roads based on the topology data of the land polygons. For example, if the acquisition unit 110 acquires polygons included in a geographic area specified by the user, the detection unit 120 determines whether each land polygon in the specified geographic area is adjacent to any public road polygon.

[0029] Specifically, when the acquisition unit 110 acquires land polygons for each plot of land, the detection unit 120 first refers to the topology data of each land polygon to determine whether the land faces a public road or a public road polygon. If the land faces any public road or public road polygon, the detection unit 120 determines that the land is not surrounding land. On the other hand, if the land does not face any public road or public road polygon, the detection unit 120 determines that the land is surrounding land.

[0030] For example, if all polygons adjacent to the land polygon being checked are land polygons, or if the land polygon being checked is surrounded by other land polygons and / or polygons other than public road polygons, it may be determined that the land does not face any public road or public road polygon.

[0031] The detection unit 120 provides the detection results, such as the detected surrounding area, to the display unit 130.

[0032] The display unit 130 displays the surrounding land on the map information. Specifically, the display unit 130 may highlight the land corresponding to the surrounding land on the map information displayed on the user's screen. For example, the display unit 130 may color the surrounding land with a different color from other land, make it flash, or mark it with a marker or other indicator. This allows the user to easily identify the surrounding land on the map information they are viewing.

[0033] According to the information processing device 100 described above, the user can visually grasp the surrounding areas within a desired geographical area by specifying that area on the map information.

[0034] [Map information display processing] Next, a map information display process according to one embodiment of the present disclosure will be described. This map information display process can be implemented by the information processing device 100, more specifically by the processor 103 of the information processing device 100 executing a program stored in the memory device 102. Figure 4 is a flowchart of the map information display process according to one embodiment of the present disclosure.

[0035] As shown in Figure 4, in step S101, the information processing device 100 acquires land polygons representing each plot of land on the map information. For example, the information processing device 100 acquires land polygons included in a geographic area specified by the user viewing the map information from one or more data sources such as a geographic information system. At this time, the information processing device 100 may further acquire various polygons included in the said geographic area.

[0036] In step S102, the information processing device 100 detects surrounding land that does not adjoin a public road based on the topology data of the land polygon. For example, the information processing device 100 determines whether a public road or public road polygon exists facing the land based on the topology data of each acquired land polygon. If no public road or public road polygon exists facing the land, the information processing device 100 detects the land as surrounding land.

[0037] In step S103, the information processing device 100 displays the surrounding area on the map information. For example, the information processing device 100 may highlight the surrounding area detected on the map information.

[0038] According to the map information display process described above, users can visually understand the surrounding areas within a desired geographical region by specifying that region on the map information.

[0039] Although embodiments of this disclosure have been described in detail above, this disclosure is not limited to the specific embodiments described above, and various modifications and changes are possible within the scope of the gist of this disclosure as described in the claims.
