Abstract
Description
Technical Field
[0001] The present invention relates to a route value verification support device, a route value verification support method, and a computer program.
Background Art
[0002] When a local government such as a municipality levies a fixed-asset tax on land, it calculates an appraisal value for all land and determines the fixed-asset tax based on that appraisal value. The fixed-asset tax in urban areas is calculated using the route value method, and the fixed-asset tax in other areas is calculated using other residential land appraisal methods. Each local government needs to calculate the fixed-asset tax for tens of thousands of pieces of land or more, and requires a great deal of labor to calculate an appropriate fixed-asset tax in a well-balanced manner for all land.
[0003] The route value of the fixed-asset tax is the land appraisal value per 1 m of residential land facing a road, which is used to calculate the tax amount of the fixed-asset tax on the land taxed by a municipality or the like, and is the value serving as the basis for calculating the tax amount. Generally, the route value is based on the appraisal value (standard residential land price) of the standard residential land for each area with similar circumstances calculated by a real estate appraiser, and is determined based on various factors such as the distance from public facilities such as stations, road width, road type (national highway, municipal road, etc.), land use regulations (urban planning, etc.). An area with similar circumstances is an area divided for each area where the usage status of residential land, the status of streets, the proximity of public facilities, or the density of houses is generally considered to be similar. A standard residential land is a residential land selected one by one for each area with similar circumstances, facing a standard road within the area with similar circumstances, and having a standard plot size or shape without plot correction. The standard residential land price is determined by appraisal evaluation or the like, and then, for each route within the area with similar circumstances, the route value is calculated according to a predetermined comparison guideline for comparing various land price-forming factors as described above from the determined standard residential land price.
[0004] Actual land prices tend to decrease as you move from central areas such as train stations towards the outskirts (the so-called trend in land prices), and unless there are differences in individual facilities attracting customers or road conditions, price fluctuations are extremely rare. However, when land values are determined based on multiple factors as described above, the influence of factors on individual roads can cause land values to fluctuate up and down (the so-called price wave), differing from the actual trend in land prices. In each municipality, land values are set for hundreds to tens of thousands of roads, depending on the size of the local government. Tax officials in local governments must review the land values of all roads each time there is a reassessment and set appropriate prices that are balanced across all roads in the administrative area. Therefore, there is a need for a system that can efficiently verify land values.
[0005] Patent Document 1 discloses a road value flowchart creation device that allows for easy visual confirmation of the flow of road values. This road value flowchart creation device acquires map data in which topology information defining the connection relationships between each section is set for each road value evaluation section, acquires the difference in road values for each section to be compared, generates arrow images from the difference, and displays them superimposed on the road.

[0021] Various embodiments of the present invention will be described below with reference to the drawings. Please note that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and its equivalents.
[0022] Figure 1 is a diagram illustrating an example of the configuration of the land price verification support system 1 according to the present invention.
[0023] The Land Value Verification Support System 1 is used by users to verify the land values of multiple roads included in a target area, and supports users in verifying land values. Land values are used for calculating fixed asset tax or inheritance tax, etc. The Land Value Verification Support System 1 consists of a Land Value Verification Support Device 100 and a terminal device M. The Land Value Verification Support Device 100 and the terminal device M are communicated with each other via a network N. The network N is an intranet or the internet, etc. The terminal device M is a device used by a user or operator, and is a personal computer, notebook personal computer, tablet PC, multifunction mobile phone (so-called smartphone), etc.
[0024] The land value verification support device 100 is a personal computer, a notebook personal computer, a server, etc. The land value verification support device 100 includes an operating device 101, a display device 102, a communication device 103, a storage device 110, and a processing circuit 120, etc.
[0025] The operating device 101 has input devices such as a keyboard and a mouse, and an interface circuit that acquires signals from the input devices. It accepts operations from the user and outputs a signal corresponding to the user's input to the processing circuit 120.
[0026] The display device 102 is an example of an output unit. The display device 102 has a display made of liquid crystal, organic EL, etc., and an interface circuit that outputs image data to the display, and displays the image data on the display according to instructions from the processing circuit 120.
[0027] The communication device 103 is an example of an output unit. The communication device 103 is equipped with a wired or wireless communication interface circuit and connects the land price verification support device 100 to a communication network. The communication device 103 performs wired communication according to a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol). Alternatively, the communication device 103 may perform wireless communication according to the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard. The communication device 103 transmits information supplied from the processing circuit 120 to an external device. The communication device 103 also supplies information received from the external device to the processing circuit 120.
[0028] The storage device 110 includes, for example, semiconductor memory such as RAM (Random Access Memory) or ROM (Read Only Memory), a fixed disk device such as a hard disk, or a portable storage device such as an optical disc. The storage device 110 stores computer programs, data, etc., used for processing by the processing circuit 120. The computer program is installed in the storage device 110 from a server (not shown) via a communication device 103. Alternatively, the computer program may be installed in the storage device 110 from a computer-readable portable recording medium using a known setup program, etc. The portable recording medium is, for example, a CD-ROM or DVD-ROM. The computer program may also be distributed from a server, etc., and installed in the storage device 110. Furthermore, the storage device 110 stores a route table 111 and a situation similarity table 112, etc. Details of the route table 111 and the situation similarity table 112 will be described later.
[0029] The processing circuit 120 is, for example, a CPU (Central Processing Unit). The processing circuit 120 may also be an LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), etc. The processing circuit 120 is connected to the operating device 101, display device 102, communication device 103, and storage device 110, etc., and controls each of these parts. The processing circuit 120 reads the program stored in the storage device 110 and operates according to the read program, thereby functioning as an acquisition unit 121, a setting unit 122, a generation unit 123, and an output control unit 124. For each of the multiple routes, the processing circuit 120 sets a predetermined range including each route and the land adjacent to each route as a land value area, and generates and outputs a three-dimensional model of the target area so that each land value area is displayed at a height corresponding to the land value of each route.
[0030] Figure 2 shows an example of the data structure of the route table 111. As shown in Figure 2, the route table 111 stores, for each of the multiple routes included in the target area, the route number, location shape information (line data), and attribute information associated with each route. The attribute information includes the route value, main line code, width, situation similarity number, and flowchart arrows.
[0031] The route number is a number assigned to each route to uniquely identify it. The positional shape information is an example of the two-dimensional shape of each route, showing the two-dimensional position and shape representing the route shape of each route. The two-dimensional position and shape of each route are composed of a sequence of points representing the coordinates of multiple vertices of polyline data that represent the route shape. Specifically, the coordinates of the vertices of the polyline data are stored sequentially, with one endpoint of the polyline data as the starting point and the other endpoint as the ending point. The coordinates of the vertices are defined, for example, by XY coordinates in a plane rectangular coordinate system to which a planar map containing the target area is mapped, or by predetermined geographic coordinates such as latitude and longitude, but are not limited to these. It may also be geometric data in any coordinate system that can represent the shape of the route.
[0032] The land value is determined by the square meter of land facing each road. 2This is the land valuation per unit. The trunk road code is a code assigned to identify a route if it is a trunk road. In addition to being able to identify whether a route is a trunk road or not, a code may be assigned in advance to each trunk road so that it can uniquely identify each trunk road, in order to classify each route by trunk road system. Each route belonging to a trunk road is assigned either a trunk road code that is uniform for trunk roads, or a trunk road code set for each trunk road system. Routes that do not belong to a trunk road are not assigned a trunk road code, and in the example in Figure 2, it is left blank. The width is the road width data used as a land price formation factor when calculating the road value of each route, but it is not always necessary. The situation similarity number is a number assigned to the situation similarity area to which each route belongs. The situation similarity number is assigned in advance to each situation similarity area so that it can uniquely identify each situation similarity area. Areas with similar conditions are areas that are further divided into land use zones, which are created by dividing the target area into categories, and then further divided into areas where the local conditions (land use, street conditions, proximity to public facilities, or density of houses, etc.) are considered to be generally similar. Land use zones are areas that classify the target area according to its current use, and include, for example, ordinary commercial zones, ordinary residential zones, mixed-use residential zones, large factory zones, and small and medium-sized factory zones.
[0033] The flowchart arrows are symbols that identify the direction of the arrows in the route diagram, which are used to show the relative values of land values for each route and the routes connected to each route. For example, "Arrow 1" is set to display an arrow pointing from the end point of a route towards the starting point, "Arrow 2" for the reverse direction, "Arrow 3" for a double arrow, and "Arrow 0" if no arrow is displayed on either side. This is done by comparing the land values of adjacent routes at the starting or ending point and setting the direction of the arrow, for example, from the route with the higher land value to the route with the lower land value. The flowchart arrows are acquired by the acquisition unit from pre-set values. However, they are not necessarily limited to those that represent the relative values of land values; all routes may have the same arrow, or the arrow shape may reflect other information.
[0034] Figure 4(A) shows an example of the data structure of the situation similarity table 112. As shown in Figure 4(A), the situation similarity table 112 stores, for each of multiple situation similar areas, the situation similarity number, situation similarity location information (polygon data), and land use zone, etc., in relation to each other.
[0035] As described above, a similar-situation area is a region divided into areas where the land use, street conditions, proximity to public facilities, or density of houses are generally considered to be similar. A similar-situation area is a unit of grouping of roads that determine the standard land parcels used as the basis for road value calculations, and in practice, it is an area that combines all the parcels whose frontage is on a road belonging to that similar-situation area. In some municipalities, a rough shape is set for a similar-situation area to the extent that it is possible to determine which road belongs to it. The similar-situation location information is an example of a two-dimensional figure of a similar-situation area, and shows the location and extent of the similar-situation area, for example, a sequence of points of coordinates of each vertex on the outer perimeter that makes up the polygon figure of the similar-situation area. The location shown in the similar-situation location information is defined by the same geographic coordinates as the coordinates shown in the road location shape information.
[0036] Figure 5 is a flowchart showing an example of the output processing flow performed by the land price verification support device 100.
[0037] The following describes an example of the operation of the output processing of the land value verification support device 100, referring to the flowchart shown in Figure 5. The operation flow described below is mainly executed by the processing circuit 120 in cooperation with each element of the land value verification support device 100, based on a program pre-stored in the storage device 110.
[0038] First, the acquisition unit 121 sets the target area specified by the user using the operating device 101 or terminal device M (step S101). The user specifies the geographical range to be verified as the target area within the area supported by the land value verification support system 1. For example, the entire area of a municipality such as a city or town may be specified as the target area. Any area such as an urbanized area or central urban area where land values have been set may be specified as the target area. Alternatively, an area based on the attribute information of a route, such as the area surrounding a main road, may be specified as the target area. The acquisition unit 121 acquires the target area specified by the user using the operating device 101 or terminal device M by receiving it from the operating device 101 or communication device 103.
[0039] Next, the acquisition unit 121 acquires location and shape information and attribute information, including the land value, for each route included in the target area (step S102). The acquisition unit 121 refers to the route table 111 and identifies the routes whose locations indicated in the location information are included in the target area. The acquisition unit 121 acquires the route number, location and shape information, and attribute information of each identified route by reading them from the route table 111. At this point, the acquisition unit 121 may also set the location and shape information, route number, and attribute information for each route entered by the user using the operating device 101 or terminal device M in the route table 111. In that case, the acquisition unit 121 may acquire the location and shape information, route number, and attribute information for each route entered by the user by receiving them from the operating device 101 or communication device 103. In this way, the acquisition unit 121 acquires the land value, trunk line code, width, situation similarity number, etc., associated with each route as attribute information for each route. Furthermore, the attribute information for each route may include flowchart arrow information for displaying adjacent routes in a manner corresponding to the relative values of their land prices, and the acquisition unit 121 acquires this information by reading the flowchart arrow information that has been set in advance in the route table 111. Alternatively, the acquisition unit 121 may identify the relative values of land prices for each combination of adjacent routes among the routes included in the target area, and based on the results, set flowchart arrow information for displaying adjacent routes in a manner corresponding to the relative values of their land prices. In this way, the acquisition unit 121 acquires information that identifies the relative values of land prices for each combination of adjacent routes among multiple routes.
[0040] Next, the acquisition unit 121 acquires the situation similarity number, situation similarity location information, and attribute information including land use district for each situation similar area included in the target area (step S103). The acquisition unit 121 refers to the situation similarity table 112 and identifies the situation similar areas in the target area whose locations are indicated in the situation similarity location information. The acquisition unit 121 acquires the situation similarity number, situation similarity location information, and attribute information for each identified situation similar area by reading them from the situation similarity table 112. At this point, the acquisition unit 121 may set the situation similarity number, situation similarity location information, and attribute information for each situation similar area entered by the user using the operating device 101 or terminal device M in the situation similarity table 112. In that case, the acquisition unit 121 may acquire the situation similarity number, situation similarity location information, and attribute information for each situation similar area entered by the user by receiving them from the operating device 101 or communication device 103. The acquisition unit 121 acquires the land use district and other information associated with each situation similar area as attribute information for each situation similar area.
[0041] Next, the acquisition unit 121 acquires a planar map corresponding to the target area (step S104). For example, a planar map including the target area is pre-stored in the storage device 110. The planar map is defined by geographic coordinates common to the coordinates shown in the route position shape information. The acquisition unit 121 acquires the planar map of the range corresponding to the target area by reading it from the storage device 110. The acquisition unit 121 may also acquire the planar map by receiving it from an external device where the planar map is stored via the communication device 103.
[0042] Next, the setting unit 122 sets the land value area for each route included in the target area (step S105). The land value area is a two-dimensional (planar) polygon. First, the setting unit 122 sets the route area to have a width corresponding to the width of each route, based on the position and shape information of each route. For example, the width of the route area for each route is set to a value obtained by multiplying the width of each route by a predetermined coefficient. If there is no information on the width of each route, the route area may be set to have a uniform width for all routes. Furthermore, the setting unit 122 sets extension areas on both sides of the set route area in the width direction perpendicular to the extension direction of each route. The extension areas are areas corresponding to the parcels (land) facing each route, that is, parcels of land for which each route is the front route and for which fixed asset tax is calculated based on the land value of each route (hereinafter sometimes referred to as adjoining parcels). The setting unit 122 sets the extension areas to have a predetermined width from the start point to the end point of each route area. In other words, the setting unit 122 sets the land value area by expanding the shape of the route from the start point to the end point of the route in the width direction by the width of the route and a predetermined width, based on the positional shape information of each route.
[0043] The width of the extension area is set, for example, to the statistical values (maximum, minimum, average, median, etc.) of the length of the adjacent plots of each route in the width direction perpendicular to the extension direction of each route. The width of the extension area may also be set or adjusted according to the land use zone of the area to which each route belongs that is similar in circumstances. In that case, for example, the width of the extension area for a route whose land use zone is a general commercial zone will be set to a smaller value than the width of the extension area for a route whose land use zone is a general residential zone. Also, for example, the width of the extension area for a route whose land use zone is a large factory zone will be set to a larger value than the width of the extension area for a route whose land use zone is a general residential zone. Furthermore, the width of the extension area may also be set or adjusted according to whether the area to which each route belongs is in the city center or the suburbs. In that case, for example, the width of the extension area for a route in the city center will be set to a smaller value than the width of the extension area for a route in the suburbs.
[0044] The setting unit 122 sets the area formed by combining the route area and the extended area as the route value area. The setting unit 122 defines the route value area for each route using, for example, XY coordinates in a plane rectangular coordinate system, or predetermined geographic coordinates such as latitude and longitude, but is not limited to these. It may also be graphic data in any coordinate system that can represent the shape of the route. In this way, based on the positional shape information of each route, the setting unit 122 sets the range within a predetermined distance from each route in the orthogonal width direction of each route as the route value area for each route.
[0045] In particular, the setting unit 122 sets the land value area for each route so as to include the land facing each route. In the processing described later, the land value area is displayed in 3D, allowing users to recognize the route for which a land value has been set and the land facing that route as a single entity, and to appropriately verify the land value for each route.
[0046] Furthermore, the setting unit 122 sets each land value area to have a width corresponding to the attributes of the routes included in each land value area. In the processing described later, the land value areas are displayed in 3D, allowing users to evaluate the land value of each route while considering the attributes of each route.
[0047] Furthermore, the setting unit 122 may correct (process) the land value area based on the flowchart arrows. For example, the setting unit 122 places flowchart arrows within the land area or extended area of each land route so that the orientation of the start and end points of each land route matches the orientation of the flowchart arrows. The setting unit 122 may also set the shape (outline) of the land value area of each land route to the shape of the flowchart arrows so that the orientation of the start and end points of each land route matches the orientation of the flowchart arrows. The setting unit 122 may also choose not to correct (process) the land value area using flowchart arrows and set the shape of all land value areas to rectangles.
[0048] Furthermore, the setting unit 122 may place strings indicating the route number, route value, etc., for each route within the route value area for each route. The setting unit 122 places the strings indicating the route number, route value, etc., for each route near the midpoint of the route value area along the extension direction of the route. The route number and / or route value for each route are placed using, for example, a known application program such as GIS or CAD. The generation unit 123 may also modify the position of the placed strings (move the strings) according to modification instructions specified by the user using the operating device 101 or terminal device M.
[0049] The width of the land price area may be set to a fixed value. Furthermore, the width of the land price area may be changed according to the display scale of the 3D model described later, or it may be fixed regardless of the display scale of the 3D model.
[0050] Figures 6(A) and 6(B) show examples of land value areas. Figure 6(A) shows land value areas R1 to R4, with flowchart arrows placed within the land value area of each route. Each land value area R1 to R4 has a route area P2 and extension areas P1 and P3 located on both sides of route area P2. Each route area P2 has a width corresponding to the width of each route, and each extension area P1 and P3 has a width corresponding to the depth of the adjacent plot of land for each route. Each route area P2 has a flowchart arrow, route number, and land value for each route. Figure 6(B) shows land value areas R11 to R14, which have the shape of the flowchart arrow for each route. Each land value area R11 to R14 has the route number and land value for each route, and the boundary line between the route area and the extension area is not displayed. By having a predetermined width for each route's land value area, the visibility of each route is improved in the 3D model described later.
[0051] Next, the setting unit 122 adjusts the overlapping portion if the land value areas of two or more routes have overlapping portions (step S106).
[0052] Figures 7(A) to 7(C) are schematic diagrams illustrating the overlapping areas at intersections where multiple routes intersect. Since the area within an intersection where multiple routes intersect is shared by multiple routes, the land value areas of the multiple routes sharing the intersection overlap with each other. In the example shown in Figure 7(A), the horizontally extending land value areas R21 and R22 and the vertically extending land value areas R23 and R24 overlap with each other in the area (overlapping portion) L1 to L4 within the intersection. Land value areas R21 and R23 overlap in overlapping portion L1, land value areas R21 and R24 overlap in overlapping portion L2, land value areas R22 and R23 overlap in overlapping portion L3, and land value areas R22 and R24 overlap in overlapping portion L4.
[0053] For example, the setting unit 122 adjusts the overlapping portion so that it is included in the land value area of the land with the highest land value and removed from the land value areas of the other land. In this case, as shown in the example in Figure 7(A), the overlapping portions L1 and L2 are adjusted to be included in the land value area R21, and the overlapping portions L3 and L4 are adjusted to be included in the land value area R22, as shown in Figure 7(B). Normally, for a plot of land located on a corner lot and facing multiple roads, the land with the higher land value is set as the front road, and the assessed value is calculated based on the land value of the land with the higher land value. By including the overlapping portion in the land value area of the land with the highest land value, the setting unit 122 can adjust the overlapping portion according to the same method as the method for determining the front road, and can set the land value area to match the user's image.
[0054] The setting unit 122 may adjust the overlapping portion so that it is allocated equally or in a predetermined proportion to the land value areas of the routes that share the overlapping portion. For example, the setting unit 122 adjusts the overlapping portion so that each position within the overlapping portion is included in the land value area of the nearest route. In this case, as shown in the example in Figure 7(A), the lower left portion of the overlapping portion L1 is included in land value area R21, and the upper right portion of the overlapping portion L1 is included in land value area R23, as shown in Figure 7(C). Similarly, the upper left portion of the overlapping portion L2 is included in land value area R21, and the lower right portion of the overlapping portion L2 is included in land value area R24. Also, the lower right portion of the overlapping portion L3 is included in land value area R22, and the upper left portion of the overlapping portion L3 is included in land value area R23. Also, the upper right portion of the overlapping portion L4 is included in land value area R22, and the lower left portion of the overlapping portion L4 is included in land value area R24. The setting unit 122 distributes each overlapping portion to each route area, thereby enabling the setting of land value areas in a way that makes it easier for users to understand the connectivity of each route, especially in residential areas where the difference in land values between each route is small. The setting unit 122 may also perform the distribution based on proximity to the land value area instead of proximity to the route. In that case, the setting unit 122 adjusts the overlapping portion so that each position within the overlapping portion is included in the land value area of the route whose area excluding the overlapping portion is closest to that position. In this case as well, in the example shown in Figure 7(A), the land value areas R21 to R24 shown in Figure 7(C) are set.
[0055] Figure 8(A) is a schematic diagram illustrating the case where land value areas overlap due to the intersection of roads in a Y-shape or similar configuration. In the example shown in Figure 8(A), land value area R31, one of the horizontally extending land value areas R31 and R32, and land value area R33, which intersects land value area R31 at an acute angle, overlap with each other in the area (overlapping portion) L5 within the intersection. When multiple land value areas overlap due to the intersection of roads in a Y-shape or similar configuration, the setting unit 122 distributes the overlapping portion so that it is included in the land value area with the higher land value. However, if one land value area crosses over the other road, the portion of the other road that crosses over will no longer face the first road. Therefore, the setting unit 122 distributes the overlapping portion L5 so that each land value area does not cross over the roads of other land value areas. The setting unit 122 then adjusts the remaining portion of the overlapping portion L5, i.e., the portion L5' sandwiched between the two roads, so that it is included in the land value area R31 with the higher land value. Furthermore, the setting unit 122 may distribute the remaining portion of the overlapping portion L5, i.e., the portion L5' sandwiched between the two routes, such that each position within the overlapping portion is included in the land value area of the nearest route, as shown in the example in Figure 7(A). In this way, the land value area is determined with an emphasis on which route the property actually faces.
[0056] Figure 8(B) is a schematic diagram illustrating a dual-route system. A dual-route system is defined for roads where the applicable route is distinct for land on one side of the road and land on the other side. Similar to cases where routes intersect in a Y-shape, the setting unit 122 sets each route value area of the dual-route system so that it does not overlap with the route of the other route value area. In the example shown in Figure 8(B), route value area R41 is set to the upper range L6 so as not to overlap with the route of route value area R42, and route value area R42 is set to the lower range L6' so as not to overlap with the route of route value area R41. This ensures that the route value areas are set so that the range to which the route value is applied is accurately represented.
[0057] Figure 8(C) is a schematic diagram illustrating the overlapping portion caused by a short route. In the example shown in Figure 8(C), the land value area R51 of the horizontally extending route and the land value area R52 of the short vertically extending route overlap at the overlapping portion L7. In this case, if the overlapping portion L7 is removed from the land value area R52 of the short route, the land value area R52 will be embedded in the land value area R51, making it difficult to see that the land value area R52 exists.
[0058] Therefore, for example, the setting unit 122 distributes the overlapping portion such that the land value area R52 of the shorter route extends into the other land value area R51. In particular, it is preferable for the setting unit 122 to distribute the overlapping portion such that the land value area R52 of the shorter route protrudes in a V-shape. In the example shown in Figure 8(C), the overlapping portion L7 is divided such that the boundary line between the land value area R52 of the shorter route and the land value area R51 has a V-shape. By distributing the overlapping portion such that the land value area of the shorter route extends into the other land value area, the setting unit 122 can set the land value area in a way that makes it easier for users to recognize the existence of the shorter route.
[0059] Figure 8(D) is a schematic diagram illustrating multiple routes to which the associated similarity areas differ from one another. In the example shown in Figure 8(D), routes corresponding to route value areas R61 to R62 belong to similarity area S1, and routes corresponding to route value areas R63 to R65 belong to similarity area S2. When the setting unit 122 expands the route value area, it does not expand it further if it crosses the boundary of a similarity area. That is, the setting unit 122 sets the route value area so as not to cross the boundary of a similarity area. If the route value areas of multiple routes belonging to different similarity areas overlap, the setting unit 122 sets the route value area for each route within the similarity area to which each route belongs. The influence range of each route applies only within the similarity area of each route. Route value areas are set using, for example, a known application program such as GIS or CAD. The setting unit 122 can apply each land value area only within the area of similar circumstances to which each land belongs by setting the land value area so as not to cross the boundaries of areas of similar circumstances.
[0060] Furthermore, even when there are geographical features such as rivers (waterways), railways, or expressways that divide the region, it is preferable for the setting unit 122 to set the land value area for each route so that the land value area does not span across these features.
[0061] Next, the setting unit 122 adjusts the gap areas within the target area that are not included in the land value area of any of the routes (step S107).
[0062] Figures 9(A) to 9(C) are schematic diagrams illustrating the gap region. In the example shown in Figure 9(A), there is a gap region Q enclosed by the horizontally extending land value regions R71 and R72 and the vertically extending land value regions R73 and R74.
[0063] For example, the setting unit 122 adjusts the gap area so that it is included in the land value area of the land that is closest to the gap area among the land value areas adjacent to the gap area. In this case, in the example shown in Figure 9(A), as shown in Figure 9(B), the upper area Q1 of the gap area Q is assigned to the land value area R71 of the closest land, and the lower area Q2 of the gap area Q is assigned to the land value area R72 of the closest land. Similarly, the left area Q3 of the gap area Q is assigned to the land value area R73 of the closest land, and the right area Q4 of the gap area Q is assigned to the land value area R74 of the closest land. When expanding the land value area to fill the gap area, it is preferable to make adjustments such as not crossing other land, not crossing areas with similar conditions, and not crossing features such as rivers, railways, and expressways. By filling in the gaps, in the three-dimensional model described later, users can compare land prices continuously, even if they face opposing, separate lines, making it easier to verify the overall balance of land values. The setting unit 122 may also perform adjustments based on proximity to the land value area instead of proximity to the road. In that case, the setting unit 122 assigns each part of the gap area so that it is included in the land value area that is closest to that part. In this case as well, in the example shown in Figure 9(A), the partial areas Q1 to Q4 shown in Figure 9(B) are assigned to land value areas R71 to R74, respectively.
[0064] Furthermore, the setting unit 122 may adjust the gap area so that it is included in the land value area of the land with the highest land value among the land value areas adjacent to the gap area. In this case, in the example shown in Figure 9(A), the gap area Q is assigned to the land value area R71, which has the highest land value.
[0065] Figure 9(C) is a schematic diagram illustrating the gap area between the road value areas of multiple routes to which the associated situation-like regions differ from each other. In the example shown in Figure 9(C), the routes corresponding to road value areas R72 to R74 belong to situation-like region S3, and the route corresponding to road value area R71 belongs to situation-like region S4. In this case, the setting unit 122 adjusts the gap area based on the position and shape information of each route and the situation-like position information of the situation-like region to which each route belongs, so that the gap area does not exceed the range of the situation-like region to which it is contained. The gap area is set so as not to cross the situation-like region, for example, using a known application program such as GIS or CAD. The setting unit 122 may also correct the position of the gap area according to correction instructions specified by the user using the operating device 101 or terminal device M. In the example shown in Figure 9(C), the gap area Q is set so as not to exceed the range of situation-like region S3. As a result, the gap area Q is not assigned to the land value area R71, the lower area Q5 of the gap area Q is assigned to the land value area R72, the left area Q6 of the gap area Q is assigned to the land value area R73, and the right area Q7 of the gap area Q is assigned to the land value area R74.
[0066] Note that the processing in step S107 may be omitted. In particular, if the land value area has the shape of a flowchart arrow, the processing in step S107 is omitted.
[0067] Next, the generation unit 123 sets a height for each road value area of the roads included in the target area, according to the road value of each road (step S108). The generation unit 123 sets the height of each road so that the higher the road value of each road, the higher the height. For example, the generation unit 123 sets the height of each road as a multiplied value obtained by multiplying the road value of each road by a predetermined coefficient. The generation unit 123 may also set the height of each road as a multiplied value obtained by multiplying the subtracted value obtained by subtracting a predetermined offset value from the road value of each road by a predetermined coefficient. The predetermined offset value is set to a value lower than the lowest road value among all the road values of all the roads included in the target area. This allows the generation unit 123 to set the height of each road so that the difference in road values of each road becomes clearer. In addition, the predetermined coefficient may be set according to the statistical values (maximum value, minimum value, mean, median, or standard deviation, etc.) of the road values of all the roads included in the target area. For example, the predetermined coefficient is set to be lower the higher the statistical value and higher the lower the statistical value. This allows the generation unit 123 to suppress the height of all routes from becoming too high or too low, and to set the height of each route so that the differences in land values for each route become clearer.
[0068] Next, the generation unit 123 generates a three-dimensional model of the land value for the target area (step S109). First, for each land value area of the routes included in the target area, the generation unit 123 generates a three-dimensional route model by expanding the two-dimensional (planar) land value area in the height direction perpendicular to the plane, according to the set height. The three-dimensional route model is an example of a three-dimensional figure of the land value area. The three-dimensional land value model is generated using a known application program such as GIS or CAD. The generation unit 123 generates the three-dimensional route model so that the land value area is placed on the upper surface of the three-dimensional route model. The generation unit 123 stores the generated three-dimensional route model for each route in the storage device 110, associating it with the attribute information of each route (land value, situation similarity number, etc.). In this way, the generation unit 123 generates a three-dimensional route model for each route so that each land value area is displayed at a height corresponding to the land value of the routes included in each land value area. The three-dimensional route model displays each route three-dimensionally according to its land value, allowing users to intuitively recognize the land value of each route.
[0069] The generation unit 123 generates a three-dimensional model of land values for a target area by placing the three-dimensional model of each route included in the target area within a three-dimensional space defined, for example, by the X and Y axes of a plane rectangular coordinate system and the Z axis orthogonal to the X and Y axes, on a geographic coordinate system common to the coordinates indicated in the location and shape information of the routes. In this three-dimensional space, the X and Y axes define the location of each route, and the Z axis defines the land value (and standard residential land price). The generation unit 123 generates the three-dimensional model of land values such that, in the three-dimensional space, the three-dimensional model of each route is placed at a position on the X and Y axes corresponding to the position indicated in the location and shape information of each route, and the bottom surface of each three-dimensional model of each route is placed at the same position on the Z axis.
[0070] Figure 10 is a schematic diagram showing an example of a land value 3D model. The land value 3D model shown in Figure 10 includes multiple land value 3D models U1 generated from land value areas in which flowchart arrows V1 are displayed and gap areas have been adjusted (filled).
[0071] Figure 11 is a schematic diagram showing another example of a land value 3D model. The land value 3D model shown in Figure 11 includes multiple land value 3D models U2 generated from land value areas in which flowchart arrows V2 are displayed and gap area adjustments are omitted.
[0072] Figure 12 is a schematic diagram showing yet another example of a land value 3D model. The land value 3D model shown in Figure 12 includes multiple land value 3D models U3 generated from land value regions having the shape of flowchart arrows.
[0073] In this way, the generation unit 123 generates a three-dimensional model of the land value of the target area so that each land value area is displayed as a three-dimensional figure having a height corresponding to the land value of the lines included in each land value area. This allows the user to intuitively recognize the land value of each line, and the land value verification support device 100 can improve user convenience. In particular, when there is a difference in the land values of adjacent lines, the side of the three-dimensional model of one of the lines is exposed. By visually inspecting the side of the three-dimensional model of the lines, the user can intuitively recognize the land value of each line.
[0074] Furthermore, the generation unit 123 generates a three-dimensional model of the land value of the target area so that each land value area is displayed as a three-dimensional figure having a configuration corresponding to the relative magnitudes of the land values of the roads included in each land value area. This allows the user to intuitively recognize the direction of change in the land value of each road, and the land value verification support device 100 can improve user convenience.
[0075] Furthermore, as described above, the acquisition unit 121 acquires information on a flowchart arrow indicating the direction from the other endpoint of a line to the endpoint of the line with the highest land value among lines where the endpoints are adjacent, in terms of magnitude relationship. The generation unit 123 generates a three-dimensional land value model such that the shape of the endpoint of each line represents the direction indicated by the flowchart arrow. This allows users to intuitively recognize the flow of land values, and the land value verification support device 100 can improve user convenience.
[0076] Furthermore, the acquisition unit 121 acquires flowchart arrows for mountain routes and valley routes that are set to be distinguishable from the flowchart arrows of other routes. A mountain route is a route included in the target area whose land value is equal to or greater than the land value of all adjacent routes at each of its endpoints. A valley route is a route included in the target area whose land value is equal to or less than the land value of any adjacent route at each of its endpoints. Note that only the flowchart of either a mountain route or a valley route may be set to be distinguishable from the flowchart of other routes. The generation unit 123 generates a three-dimensional land value model based on the flowchart arrows of each route so that the land value area of the mountain route and / or the land value area of the valley route can be displayed in a way that distinguishes them from the land value areas of other routes. Note that the generation unit 123 may display the three-dimensional land value model of the mountain route, the three-dimensional land value model of the valley route, and / or the three-dimensional land value model of other routes in mutually different colors. This allows users to visually recognize the trends in land values, and the land value verification support device 100 can improve user convenience.
[0077] The generation unit 123 may make the colors of the top and sides of the three-dimensional land value model different from each other. In that case, the generation unit 123 may make the color of the sides of the three-dimensional land value model darker than the color of the top. This makes the land value of each road shown in the three-dimensional land value model clearer, and makes it easier for users to recognize the land value of each road.
[0078] Next, the output control unit 124 generates display data for displaying the land value 3D model and outputs the display data by displaying it on the display device 102 or by transmitting it to the terminal device M via the communication device 103. When the terminal device M receives the display data from the land value verification support device 100, it displays the received display data on a display unit (not shown). The output control unit 124 generates the display data so as to project the land value 3D model onto a projection plane specified by the user within the three-dimensional space in which the land value 3D model is defined.
[0079] Next, the acquisition unit 121 extracts one or more routes from among the routes included in the target area that are subject to verification of their land value (step S110). For example, the acquisition unit 121 refers to the route table 111 and extracts routes from among the routes included in the target area that have been stored with associated trunk road codes (routes belonging to trunk roads) as routes to be verified. The acquisition unit 121 may also extract routes from among the routes included in the target area that have been stored with associated trunk road codes by the user using the operating device 101 or terminal device M (routes belonging to trunk roads specified by the user) as routes to be verified. In addition, in the route table 111, an arbitrary group to which each route belongs may be set, and the acquisition unit 121 may extract routes belonging to the group specified by the user using the operating device 101 or terminal device M as routes to be verified. The groups are groups based on regional characteristics, such as a group of routes located in a bustling area in front of a station, or a group of routes located in a coastal industrial area. Furthermore, the acquisition unit 121 may extract all routes included in the target area as routes to be verified.
[0080] Next, the generation unit 123 places the route number and / or land value of each route on the three-dimensional land value model (step S111). The generation unit 123 places a string indicating the route number and / or land value of each route within or around the land value area placed on the upper surface of the three-dimensional land value model of each route. The generation unit 123 places the string indicating the route number and / or land value of each route at the same position as the upper surface of the three-dimensional land value model of each route on the Z axis, and near the midpoint of the route shape along the extension direction of the route. The generation unit 123 may also place the string indicating the route number and / or land value of each route slightly above the height of the three-dimensional land value model on the Z axis. This allows the generation unit 123 to improve the visibility of the route number and / or land value. The generation unit 123 may also place the string indicating the route number and / or land value of each route along the horizontal direction of the screen on which the three-dimensional land value model is displayed. The route number and / or land value for each route are entered using a known application program such as GIS or CAD. The generation unit 123 may also modify the position of the entered strings (move the strings) according to modification instructions specified by the user using the operating device 101 or terminal device M. If a string indicating the route number and / or land value is already entered in the land value area, this process is omitted.
[0081] Next, the generation unit 123 places a background map on the road value 3D model (step S112). The generation unit 123 places a planar map acquired by the acquisition unit 121 in step S104 as a background map on the road value 3D model. The background map includes general topography such as roads, railways, and rivers, and annotation strings such as place names, stations, and landmark facilities (public facilities or commercial facilities, etc.). The generation unit 123 divides the background map into areas corresponding to the road value areas. The generation unit 123 overlays each divided background map onto the upper surface of the road value 3D model corresponding to the road value area. That is, the generation unit 123 places each divided planar map at corresponding positions on the X and Y axes, and at the same position as the upper surface of each road value 3D model on the Z axis. The generation unit 123 may place each annotation string included in the background map at a position equivalent to or slightly higher than the upper surface (land value area) of the route 3D model located at a position overlapping with each annotation string or around each annotation string. Alternatively, the generation unit 123 may place the background map at a position equivalent to or slightly higher than the upper surface (land value area) of the route 3D model of the route with the highest land value among the route 3D models placed in the land value 3D model. The background map is placed using a known application program such as GIS or CAD. By placing the background map in the land value 3D model, users can correctly recognize which route each route 3D model in the land value 3D model corresponds to, and the land value verification support device 100 can improve user convenience.
[0082] Figure 13 is a schematic diagram showing an example of a three-dimensional land value model with route numbers, land values, and a background map. The three-dimensional land value model shown in Figure 13 is the same as the one shown in Figure 10. As shown in Figure 13, the top surface of each three-dimensional land value model U1 is filled with the string W indicating the route number and land value, as well as the background map T. The display of land values allows users to check the land value of each route while viewing the price differences between routes and the distribution of land values. In addition, the display of route numbers and the background map T allows users to easily understand which route each three-dimensional land value model U1 corresponds to.
[0083] Next, the output control unit 124 generates (updates) display data for displaying the adjusted land value 3D model, and outputs the display data by displaying it on the display device 102 or by transmitting it to the terminal device M via the communication device 103 (step S113). With this, the output process is completed.
[0084] The generation unit 123 may generate a 3D route model at predetermined time intervals, and the output control unit 124 may generate display data to continuously display (animated) the 3D route models at predetermined time intervals. The output control unit 124 may also switch the display of flowchart arrows, various strings, and / or part or all of the background map according to instructions from the user using the operation device 101 or terminal device M. The output control unit 124 may also rotate, slide, and / or enlarge or reduce the 3D route value model in any direction according to instructions from the user using the operation device 101 or terminal device M. By rotating the 3D route value model, the user can see the 3D route models hidden behind the 3D route models of road surfaces with high road surface values.
[0085] Furthermore, the generation unit 123 may display the relative values of the land values of each route in a manner other than, or in addition to, displaying them by the direction of the arrows in the three-dimensional model of each route. For example, the generation unit 123 may display the relative values of the land values of each route by the height of each route. For routes where the arrow shape "arrow 1" is set (upward route), the generation unit 123 generates the three-dimensional model of the route so that it gets higher from the starting point to the ending point, instead of or in addition to the arrow pointing from the starting point to the ending point. Also, for routes where the arrow shape "arrow 2" is set (downward route), the generation unit 123 generates the three-dimensional model of the route so that it gets lower from the starting point to the ending point, instead of or in addition to the arrow pointing from the ending point to the starting point. Furthermore, the generation unit 123 may display the relative values of the land values of each route by the color of each route. In that case, the generation unit 123 generates a three-dimensional route model such that for an upward route, the density or saturation increases from the starting point to the ending point, and for a downward route, the density or saturation decreases from the starting point to the ending point.
[0086] Furthermore, the generation unit 123 may display the three-dimensional route model of each route in a predetermined color according to the land value of each route and / or the land use district of the area to which each route belongs that is similar in circumstances.
[0087] Furthermore, the generation unit 123 may identify mountain routes and / or valley routes by comparing their land value areas with adjacent routes, rather than by comparing them with adjacent routes at the starting and ending points. For example, the generation unit 123 adjusts (fills in) the gaps in each land value area for each route included in the target area, and as a result, identifies routes where land value areas are adjacent to each other. If the land value of the route of interest is greater than or equal to the land values of all identified routes, the generation unit 123 identifies the land value area of the route of interest as a mountain route land value area. On the other hand, if the land value of the route of interest is less than or equal to the land values of all identified routes, the generation unit 123 identifies the land value area of the route of interest as a valley route land value area. The generation unit 123 generates a three-dimensional land value model so that the identified mountain route land value areas and / or valley route land value areas can be distinguished from the land value areas of other routes. Furthermore, the generation unit 123 may display the colors of the 3D route models for mountain routes, valley routes, and / or other routes in mutually different colors. This allows users to visually recognize the flow of land values in more detail, and the land value verification support device 100 can improve user convenience.
[0088] Furthermore, steps S106-S107 and S110-S113 may be omitted. Also, each land price area does not need to be displayed in a manner that corresponds to the relative magnitudes of the land prices included in each land price area.
[0089] As explained above, the land value verification support device 100 sets a range within a predetermined distance in the width direction from each road as a land value area, and generates and displays a three-dimensional land value model so that each land value area is displayed at a height corresponding to the land value of each road. This allows users to intuitively recognize the land value of each road while being aware of the parcels of land facing each road. Therefore, the land value verification support device 100 enables users to verify land values more efficiently.
[0090] While displaying the flow of land values as arrows on a plane makes it easy to grasp local trends in land values, it is difficult to grasp broader trends. For example, the arrows showing the flow of land values may spiral in areas such as residential neighborhoods. When the flow of land values is displayed as arrows on a plane, users need to follow the flow of the arrows, making it difficult to intuitively grasp the broader flow of land values. Furthermore, the balance of land values between adjacent lines cannot be represented solely by arrows on a plane, and users ultimately need to verify the actual values of the land values. Also, even if only the flow of land values for each line is displayed, it is difficult for users to visualize the land facing the line. The land value verification support device 100 uses a land value area that corresponds not only to the line but also to the land facing the line, making it easier for users to visualize the land facing the line. In addition, the land value verification support device 100 displays the land value area at a height corresponding to the land value, allowing users to intuitively grasp the broader flow of land values and the land values themselves. As a result, users can more easily grasp the balance of land values not only between adjacent land values but also across a wider area, enabling them to appropriately verify the land values of each route within the target area.
[0091] Those skilled in the art will understand that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention.
