FIG. 2 shows a configuration diagram of the embodiment of the present invention. Reference numeral 20 denotes a land information management system, which is related to land ownership management. This is a type of land management unit called “brush”, which is classified according to the position and shape of the land, and information on the land such as the owner, texture and area as the attributes of the land.
[0010]
As for the shape of the land, the boundary of the land is stored as a line segment, and is displayed as a map of the land on a display device or paper. It is used in the business of always clarifying the right relationship by performing change processing in accordance with the transfer of ownership in the sale and inheritance of land.
[0011]
The land information management system 20 includes a land information database including a land attribute information table 27 and a land parcel information table 26, a data input / output device, in particular, a display 28 for displaying classified land related to the present invention, and a new attribute. And a pointer 21 for indicating a display position.
[0012]
The control of the system is executed by four means provided and functioning as a computer program. A point indication unit 22 that detects a position indicated when a pointer is indicated on a map on the screen by a user, and a land parcel information table 26 to which parcel the designated position belongs are searched. The land search unit 23, the attribute of the searched land section, the attribute search unit 24 for searching the land attribute information table 27, and the searched attribute, for example, the name of the owner of the land correspond to the designated position on the map. The display unit 25 is displayed on the screen of the display 28.
[0013]
FIG. 3 shows an example of a screen according to the embodiment of the present invention. A square indicated by a double line frame is the screen 30 of the display 28. On the screen, there are four categories of land with owner names A, B, C and E. The display of the owner name on the screen is arranged at a position designated by the user as a result of implementing the present invention.
[0014]
Conventionally, these display positions are mechanically determined and displayed at the center of the vertical and horizontal ranges occupied by each land section. For example, the land section of the owner A is actually displayed on the screen as indicated by a dotted line. It was also connected to the outside and displayed at the position of the circle 33, which is the center position. In addition, for the land of the owner name C indicated by (f), (j), (m), (k), (h), and (i), the end points indicating the land divisions (referred to as the brush boundary point) are conventional. Was displayed at the position of the circle 35. In such display positions, the display of the owner name of the land could not be recognized or could be mistakenly recognized. As illustrated above, the land section is surrounded by a plurality of line segments, and the connection points of the lines are indicated by lowercase letters with parentheses.
[0015]
FIG. 4 shows a structure explanatory diagram of the land information database. The land attribute information table 41 shown in FIG. 4A stores a land ID, an owner name, a texture, and a land area with characters and lot numbers as identifiers corresponding to the above-described screen example. Further, the land section information table 42 in FIG. 4B stores the position and shape of the land section corresponding to the land ID. The land divisions are displayed as a list of stroke points with the coordinates of each end point of a continuous line segment, with the east-west position being the X coordinate and the north-south position being the Y coordinate.
[0016]
For example, for the owner B, the land ID is 10-30-10, that is, the large letter, the small letter, and the lot number are IDs, the owner name is B, the residential land with an area of 100 square meters, and the positions are (j) and (g) in FIG. , (K), (m) are stored as coordinates (Xj, Yj), (Xg, Yg), (Xk, Yk), (Xm, Ym).
[0017]
The land parcel information held in the land parcel information table 42 as described above is displayed on the screen 30, and the owner name of the land parcel designated by the user is read from the land attribute information table 41 and displayed on the screen. The operation of displaying at the position designated by the user will be described according to the attribute display flowchart of FIG.
[0018]
In step S51, the user instructs the optimal display point in the above-mentioned section on the map displayed on the screen by the mouse pointer 21 so that the owner name of the land section is displayed at an easy-to-see position. I press the button. The point instruction unit 22 passes the position of the point indicated on the screen to the land search unit 23 as XY coordinates.
[0019]
In step S52, the land search unit 23 searches the land block information table 42 for the ID of the land block including the passed XY coordinates. That is, each land parcel is searched for whether or not the designated XY coordinates are included in the area surrounded by a plurality of points in the brush boundary list of the land parcel table 42, and the corresponding land ID is searched. The determination of whether or not a point in a closed region connecting a plurality of points is included is generally carried out in devices that operate the screen in addition to CAD and drawing software. For example, for a combination including the X coordinate of the specified point between the X coordinates of two adjacent brush boundary points, the number of combinations where the specified point is on a straight line connecting the two brush boundary points Can be determined to be included in the closed region.
[0020]
In step S53, the land attribute information table 41 is searched corresponding to the detected land ID, and the owner name of the land is obtained as an attribute to be displayed.
In step S54, the owner name is displayed on the land block so as to center on the point designated by the pointer.
[0021]
Note that the display position of the owner name may be displayed centered on the instructed position, may be displayed with the position as the head, or may be displayed in a predetermined positional relationship.
In the above description, the display position on the screen has been described. However, the display position as a printed material can be similarly realized.
[0022]
Furthermore, the present invention can also be applied to a case where a graphic other than a map is displayed for each closed partition area.
A technique for painting an area surrounded by a closed curve is also used in the public domain. realizable.
[0023]
