[0002]

2. Description of the Related Art An application (application for an entry) for obtaining an entry stored in a registry is made based on a lot number. This lot number is different from the house display that the general user recognizes as an address. Most users do not know the lot number, so in order to apply for an entry, first of all, the corresponding lot number must be checked based on the residence display.

Therefore, the applicant has developed a technique for associating a lot number display map based on a lot number with a house display map based on a house display, and applied for a patent application 2000-333451. According to the technique disclosed in Japanese Patent Application No. 2000-333451, the lot number display map and the residence display map are displayed in an overlapping manner, and the other is acquired based on one of the lot number and the residence display.

[Problems to be Solved by the Invention] In the lot number display map (Ministry of Justice map) provided in the registry office, a map based on Article 17 of the Real Estate Registration Law (Law Article 17 map) and other than this Law Article 17 map There are public figures that are various drawings of. The Article 17 map of the law is an accurately created map, and it is desirable that this Article 17 map be created for all areas. However, at present, this Law Article 17 map has not been prepared for many areas. Public maps are used for areas where there is no Article 17 map. Generally, public maps are map-like drawings that show only the outline of the position and shape of land, and their accuracy is low. Therefore, if a public map is used as the lot number display map, it may be difficult to accurately associate the public map with the house display map.

Therefore, it is an object of the present invention to provide a map information management system capable of accurately associating a lot number display map and a house display map.

[0006]

In order to solve the above problems, the present invention adopts the following configurations.

That is, the map information management program of the present invention is characterized by causing a computer to execute the following procedure. These procedures show the map data of the lot number display including the boundary information of the lot number display indicating the boundary of the region corresponding to the lot number based on the coordinate system, and the boundary of the region corresponding to the house display based on the coordinate system. An acquisition procedure for acquiring the map data of the house display including the boundary information of the house display, and a pair of reference points on the surface shown in one of the both map data,
And a reference point specifying procedure for specifying a pair of reference points respectively corresponding to the reference points on the other surface of the map data, and coordinates of the reference points according to the coordinate system of the map data of the lot number display. Based on the values and the coordinate values of the two reference points in the coordinate system of the map data of the house display, the conversion relationship between the two coordinate systems is analyzed to match the one coordinate system of the both map data. And a conversion procedure for converting the other coordinate system, one or more auxiliary reference points other than the reference points on the surface shown in one of the map data, and the other surface of the map data. And an auxiliary reference point specifying procedure for specifying one or more auxiliary reference points corresponding to the auxiliary reference point, and for the auxiliary reference point in one of the both map data, the other map corresponding to the auxiliary reference point. Proximity of auxiliary reference points in data In so that, from the deformation steps of deforming the other map data is composed of at least.

With this configuration, when the other map data is less accurate than the other map data, the other map data is transformed according to the one map data. Therefore, both map data are correctly matched.

The user can also acquire the lot number based on the house number, and can also obtain the house number based on the lot number. In either case, both map data that correspond to each other in the desired area are displayed in an overlapping manner.

The coordinate value table 212 has a "point number" field for each boundary point, and "x coordinate" and "y coordinate" fields as coordinate values of the boundary point. The house display map is represented by a coordinate system unique to the house display map. For example, this coordinate system is a two-dimensional Cartesian coordinate system. Then, the pair of coordinates of this residence display map are distinguished from the coordinate system of the above-mentioned lot number map to be "x coordinate" and "y coordinate". That is, on the lot number map, all points are (x, y) in the xy coordinate system.
It is expressed in the form of.

The house display attribute DB 12 stores various kinds of information regarding the house display map.

The map search system 30 includes an input device such as a keyboard and a pointing device, a CRT or an LCD.
A computer having a display device such as the above and a storage device is provided. Then, in the storage device of the map search system 30, the house display map DB 31, the house display attribute DB
32, a reference point DB 33, and a display work DB 34 are stored. The data in each of the DBs 31 to 34 is created and accumulated in the processing (registration processing and search processing) described below.

<Registration Processing> The map search system 30 previously executes the following registration processing in order to execute the search processing described later. That is, the map search system 30 performs a registration process for associating the lot number display map and the house display map with each other so that the user can display the lot number display map and the house display map in an overlapping manner by the search process. To execute.

FIG. 5 is a flow chart showing the registration process. The process according to this flowchart is started by the worker performing an operation for starting the registration process on the map search system 30. In addition, the flowchart of FIG. 5 shows an area corresponding to one map number (process target map number) in the lot number display map.
This is the process to be executed. The flowchart of FIG. 5 is
It is executed individually for all the map numbers of the lot number display map.

First S00 after the start of the flowchart of FIG.
In 1, the map search system 30 identifies a pair of reference points based on the operation of the operator. Specifically, the operator operates the input device of the map search system 30 to acquire the lot number display map and the house display map corresponding to the lot number display map, and displays the reference point input screen on the display device. . FIG. 6 is a schematic diagram showing this reference point input screen. On this reference point input screen, a lot number display map and a house display map corresponding to the lot number display map are displayed. The shapes of the lot number display map and the house display map are different from each other. Therefore, the worker selects a pair of reference points which serve as a reference for associating the two. That is, the worker
Points that are recognized to be the same in both are selected as reference points, and the pointing device is operated to specify them in the map search system 30. As schematically shown in FIG. 6, a pair of reference points α and β are designated respectively.

In one of the lot number display maps, the coordinates of the reference point α are represented as (X, Y) = (Xα, Yα), and the coordinates of the reference point β are (X, Y) = (Xβ, Yβ). expressed. On the other house display map, the coordinates of the reference point α are (x, y) =
It is expressed as (xα, yα), and the coordinates of the reference point β are (x, y)
= (Xβ, yβ). The coordinate values of these reference points are registered in the reference point DB 33.

In the next S002, the map search system 30
Converts the coordinates of the residential display map using both reference points α and β as references and associates them with the lot number display map. Specifically, the map search system 30 uses the following S002 to S002.
According to, coordinate conversion is executed.

In S002, the map search system 30
Is the distance L1 between the reference points α and β based on one coordinate system (X, Y) and the distance L2 between the reference points α and β based on the other coordinate system (x, y) It is calculated based on each.

L1 = {(Xβ-Xα) ² + (Yβ-Y
α) ² } ^1/2 L2 = {(xβ-xα) ² + (yβ-yα) ² } ^1/2 Then, the map search system 30 uses the coordinate system () of the house display map based on these L1 and L2. A coefficient W W = L1 / L2 for converting (x, y) into the coordinate system (X, Y) of the lot number display map is calculated. When this W is multiplied by the coordinate value of the house display map, the scale and unit system of this coordinate value match that of the lot number display map.

In S002, the map information management 30 system acquires the data of the house display map DB 21 from the house display map management system 20. Then, the map search system 30 converts the coordinate values of all points on the house display map included in the acquired data into the coordinate system (X, Y) of the lot number display map. That is, by multiplying the coordinate value of each point on the house display map by W, the coordinate value (Wx, Wx) of each point according to the scale of the XY coordinate system and the unit system.
y) is obtained.

In S002, the map search system 30
Performs offset correction of the coordinate value (W · x, W · y) obtained in S002. That is, (Wx, Wy)
The offset correction is performed so that the origin position of is coincident with the origin position of the XY coordinate system of the lot number display map. The offset (ΔX, ΔY) between the two origin positions is expressed as (ΔX, ΔY) = (Xα−W · xα, Yα−W · yα). Then, each point of the house display map is (X, Y) = (Wx + ΔX, Wy + ΔY) ∴ (X, Y) = (Wxx + Xα-Wxx, W depending on the coordinate system of the lot number display map.・ Y + Y
α-W · yα).

Based on the coordinate values of the house display map in the XY coordinate system thus obtained, the house display map DB 31 whose coordinates have been converted is created. FIG. 7 is a schematic diagram showing the house display map DB 31. Specifically, the map search system 30 creates a new coordinate value table 312 including the coordinate values after coordinate conversion, and stores the new coordinate value table 312 in the storage device together with the connection table 311 as the house display map DB 31. The connection table 311 has the same contents as the connection table 211 (FIG. 4) of the house display map DB 21 in the house display map management system 20.

In the next S003, the map search system 30
Determines whether the lot number display map indicated by the map number to be processed is a public map and branches the processing. That is, the “type” corresponding to the map number of the processing target in the lot number display attribute DB 12 (FIG. 3) is referred to. If the type is “public map”, the process proceeds to S005 and “17” (17) If it is a map), the process proceeds to S004.

In step S004, the lot number display map indicated by the map number to be processed is a highly accurate 17-section map, so the map search system 30 determines that no further correction is necessary and determines that the house display attribute DB 32 is stored. Perform accumulation only.
That is, the map search system 30 acquires the record of the house display attribute DB 22 in the house display map management system 20, adds the information of “type” and “map number” to the acquired data, and adds it to the house display attribute DB 32. accumulate. FIG. 8 is a schematic diagram showing the house display attribute DB 32. For example, as shown in the record on the third line of the house display attribute DB 32, “17” is stored in the “type” field. This indicates that the lot number display map corresponding to the area indicated by the "residential display number" of the record is a 17-row map. After the accumulation is done, the process ends.
In the case of the Article 17 map, the "map number" field may not be set.

In S005, the lot number display map indicated by the map number to be processed is a public map with low accuracy, so the map search system 30 specifies an auxiliary reference point for further correction. Specifically, the operator operates the pointing device to set one or more auxiliary reference points on the reference point input screen of FIG. FIG. 9 is a schematic diagram showing a screen on which auxiliary reference points (auxiliary points) are set. As the coordinate values of these auxiliary reference points I, II, III, the lot number display map DB1
Both the coordinate value set corresponding to the data of 1 and the coordinate value set corresponding to the data of the house display map DB 31 are added to the reference point DB 33. Note that the correction based on these auxiliary reference points I, II, and III is executed in the search process described later.

It is not essential for the worker to input the auxiliary reference point in S005. However, if the auxiliary reference point is not input, no further correction will be made in the search processing described later.

In the next S006, the map search system 30
Executes accumulation of the house display attribute DB 32. That is, the map search system 30 is the residence display map management system 20.
The record of the house display attribute DB 22 in is acquired, the information of “type” and “map number” is added to the acquired data, and the record is stored in the house display attribute DB 32 (FIG. 8). For example, as shown in the record on the first line of FIG.
"Public chart" is stored in the "Type" field. this is,
It indicates that the lot number display map corresponding to the area indicated by the "residential display number" of the record is a public map. Also,
In the field of "map number" in the record on the first line of FIG. 8, the map number of the lot number map corresponding to the area shown in the house display is stored. Residential display attribute DB32
After the data is stored in the, the processing ends.

<Search Processing> After the above registration processing has been performed, the user operates the map search system 30 to execute the search processing, and
You can browse the screen where the lot number display map and the house display map are superimposed. FIG. 10 is a flowchart showing this search processing.

In the first S101, the map search system 3
0 acquires the house display. That is, when the user operates the input device,
Enter the address (address) of the house you want to browse.

In the next S102, the map search system 30
Acquires the coordinate value of the boundary point corresponding to the house display acquired in S101 by searching the house display map DB 31 (FIG. 7). Specifically, the map search system 30
Identifies each point number of the connection table 311 based on the house display, and acquires the coordinate value of the identified point number based on the coordinate value table 312.

In the next S103, the map search system 30
Calculates the center of gravity of the boundary point acquired in S102. For example, in S102, the point A (Xa, Y
a), the point B (Xb, Yb), the point C (Xc, Yc), and the point D (Xd, Yd) are acquired, the coordinate value of the center of gravity (X, Y) = (X double, Y) Weight) is calculated as X weight = (Xa + Xb + Xc + Xd) / 4 Y weight = (Ya + Yb + Yc + Yd) / 4. When the area based on each point has a shape other than a rectangle, the center of gravity defined by the geometrical properties of the figure may be calculated.

In the next S104, the map search system 30
Extracts the coordinate values of the boundary points included in a predetermined range centered on the center of gravity calculated in S103 with reference to the house display map DB 31 (FIG. 7). The predetermined range (corresponding to the display area) is defined by, for example, a condition of X weight ± 50 m and Y weight ± 50 m.

In the next S105, the map retrieval system 30
Searches the house display attribute DB 32 (FIG. 8) for S10
"Type" of the record corresponding to the house display acquired in 1
To get

In the next S106, the map search system 30
Advances the process to S107 if the type acquired in S105 is “public chart”, and advances the process to S111 if the type is “17”.

At S107, the map search system 30
“Map number” of the record corresponding to the house display acquired in S101 by searching the house display attribute DB 32 (FIG. 8)
To get

In S108, the map search system 30
Based on the map number acquired in S107, the coordinate value of the boundary point (boundary point) of the lot number display map is acquired. Specifically, the map search system 30 is a lot number display map management system 10
Of the lot number display attribute DB 12 (FIG. 3) to obtain the lot number corresponding to the map number, and the point number of the writing boundary point corresponding to the obtained lot number is set to the connection table 111 of the lot number display map DB 11 (FIG. 2). The coordinate value of the specified point number is acquired based on the coordinate value table 112.

In S109, the map search system 30
Since the data of the lot number display map DB 11 is created on the basis of the public map with low accuracy, the lot number display map is deformed in correspondence with the house display map to perform the correction. This correction is S in the registration process of FIG.
This is done based on the auxiliary reference point specified in 005.

This correction is performed by executing the following processing of S109 to S109 for all of the writing boundary points specified in S108. However, in order to simplify the explanation, one writing boundary point P (coordinate value: (X,
The correction process regarding Y) = (Xp, Yp)) will be described in detail. Further, as shown in FIG. 9 above, description will be given assuming that the auxiliary reference points I, II, and III are specified.
In addition, the coordinate values of the auxiliary reference points I, II, and III set corresponding to the data of the lot number display map DB 11 are represented by (X,
Y) = (X <I>, Y <I>), (X <II>, Y <I
I>), (X <III>, Y <III>), and the coordinate values of the auxiliary reference points I, II, and III set corresponding to the data of the house display map DB 31 are (X, Y) =
(X [I], Y [I]), (X [II], Y [II])
(X [III], Y [III]).

In S109, the map retrieval system 30
Are the coordinate values of the auxiliary reference points I, II, III set for the data of the house display map DB31 and the auxiliary reference points I, I set for the data of the lot number display map DB11.
The difference from the coordinate values of I and III is calculated.

FIG. 11 is an explanatory diagram of the correction process. In FIG. 11, the auxiliary reference points I, II, and III set corresponding to the data of the house display map DB31 are indicated by stars, and the auxiliary set corresponding to the data of the lot number display map DB11. The reference points I, II, III are indicated by black circles. The difference between the coordinate values corresponds to the distance between the black circle and the star mark that correspond to each other.

The difference ΔXI regarding the auxiliary reference point I is expressed by the following equation ΔXI = (X [I], Y [I])-(X <I>, Y <I.
>) And the difference ΔX with respect to the auxiliary reference point II
II is represented by the following formula ΔXII = (X [II], Y [II])-(X <II
>, Y <II>), and the difference Δ with respect to the auxiliary reference point III
XIII is represented by the following formula ΔXIII = (X [III], Y [III])-(X <
III>, Y <III>).

In S109, the map search system 30
Is each auxiliary reference point I corresponding to the boundary point P and the display of the house.
Distances M1, M2 and M3 from II and III are calculated, and the minimum value of them is determined. For example, M1 = 20, M
If 2 = 10 and M3 = 100, M2 = 10 is determined as the minimum value.

In S109, the map search system 30
Acquires a correction value (ΔXp, ΔYp) which is a displacement amount for displacing the writing boundary point P. The correction value ΔXp is calculated by the following formula ΔXp = ΔXI · M2 / M1 + ΔXII · M2 / M2 +
The correction value ΔYp calculated by ΔXIII · M2 / M3 is expressed by the following equation ΔYp = ΔYI · M2 / M1 + ΔYII · M2 / M2 +.
Calculated by ΔYIII · M2 / M3.

For example, M1 = 20, M2 = 10, M3 =
100, ΔXp = ΔXI · 0.5 + ΔXII + ΔXIII · 0.
1 ΔYp = ΔYI · 0.5 + ΔYII + ΔYIII · 0.
It becomes 1. That is, the writing boundary point P is affected by a larger correction from the auxiliary reference point having a shorter distance.

In S109, the map search system 30
Displaces the boundary point P. When the coordinate value of the brush boundary point after displacement is (Xp ′, Yp ′), Xp ′ = Xp + ΔXp Yp ′ = Yp + ΔYp.

By performing the correction processing of S109 to S109 on all the writing boundary points, the data based on the low accuracy public map is transformed according to the data based on the house display map. And the map search system 30
Registers the data including the corrected coordinate value of the writing boundary point in the display work DB 34. FIG. 12 shows the display work DB 34.
It is a schematic diagram which shows. The connection table 341 of the display work DB 34 is a copy of the connection table 111 of the lot number display map DB 11, but the coordinate value table 34
In 2, the coordinate value of the writing boundary point after displacement due to correction is stored.

In the next S110, the map search system 30
Displays the lot number display map and the house display map on the display device and outputs them. Specifically, the map search system 30 creates image data in which the boundary points of the house display map extracted in S104 are connected. That is, the house display map D
B31 connection table 311 and coordinate value table 312
Based on, the image data of the house display illustrated in FIG. 13 is created. In the area surrounded by the boundary line, the corresponding house display number is displayed.

Then, the map retrieval system 30 executes S10.
X of the coordinate values of the boundary points of the house display map extracted in 4
The maximum value Xmax of the coordinates and the maximum value Ymax of the Y coordinates are acquired. Then, the map search system 30 refers to the display work DB 34, and Xmin ≦ X ≦ Xmax and Y
A brush boundary point that satisfies the condition of min ≦ Y ≦ Ymax is specified. Further, the map search system 30 connects these brush boundaries based on the display work DB 34 to create the image data of the lot number display illustrated in FIG. 14. The corresponding lot number is displayed in the area (brush) within the boundary line (border line). This lot number is displayed in italic to distinguish it from the house display, but may be displayed in a different color from the house display.

Then, the map search system 30 superimposes the image data of the house display (FIG. 13) and the image data of the lot number display (FIG. 14), and the superimposed image (display map data) shown in FIG. Is created, displayed on the display device, and the process ends. By looking at this image, the user can know the relationship between the residence display and the lot number regarding the desired area.

On the other hand, in S111, the map search system 3
0 indicates that the data of the lot number display map is based on the Article 17 map, so the lot number display map DB1 is not corrected.
The image data of the lot number display is created based on the data extracted from No. 1, and the image data of the house display is displayed and displayed on the display device, and the process is ended.

<Modification> In the above embodiment, as shown in FIG. 15, the image data of the lot number display and the image data of the residence display are superimposed. FIG. 16 is a schematic diagram showing a superimposed image according to a modification. In FIG. 16, only one brush boundary line based on the lot number display is overlaid on the image data of the house display by a dotted line. That is, when there are a plurality of lot numbers (brushes) to be displayed, the map search system 30 displays only the brush boundary lines that are the boundaries between these brushes with dotted lines. The lot number is displayed in italics as in the above. For example, the lot numbers “7-3” and “7” in FIG.
-4 "is the display target, the map search system 30
Refers to the connection table 341 and points 14 and 11
It is determined that the group of point numbers of No. is common to both lot numbers, and only the group of point numbers of this point 14 and point 11 are connected and displayed by a dotted line as a boundary line. Boundary lines corresponding to other sets of point numbers are not displayed. If there is only one brush to be displayed, the brush boundary line is not displayed.
