The house map data file 6 represents a map of a predetermined range, for example, a road map within the range of one administrative boundary, and data of a house map for specifying names and display shapes of various real estates on this road map. Yes, Figure 2 (a),
As shown in (b) and (c), wide-area map graphic data 61 for displaying the entire range of one administrative boundary, and this wide-area map is divided into a plurality of planes of a predetermined size, and each divided area is divided. The map is composed of narrow-area map graphic data 62 representing the details of the interior of the house, and house map data 63 representing the shapes of houses, roads, and various real estates in the divided areas by further dividing the narrow-area map.
Further, the values of the X coordinate and the Y coordinate on the map of each real estate in the house map data 63 are set.

[0008] The city planning map data file 7 is created by the municipalities based on the basic city map in the future, and is read by an image reading device such as a scanner. Figure data 6
2. Image data is made in accordance with the house map data 63.

Further, the aerial photograph data file 8 has a camera mounted on an airplane, takes an aerial photograph from a high photographing altitude above the sky, reads the aerial photograph by an image reading device such as a scanner, and reads wide-area map graphic data 61, This is converted into image data in accordance with the narrow-area map graphic data 62 and the house map data 63.

On the other hand, the land price data table 9 is data for specifying the position, location, and land price of various real estates on a road map. As shown in FIG. 3, the coordinates (X, Y), location, It is composed of land price data such as lot numbers, transaction prices, and transaction points. As shown in FIG. 6, the land price data 90 includes, in addition to the location and the lot number, the type of land, the transaction price, the transaction time, the presence or absence of the transaction circumstances, the street condition, the traffic / approach condition, the drawing condition, Items necessary for real estate transactions such as administrative conditions are entered.

Next, the map display operation of the land price display method and system configured as described above will be described with reference to the flowchart of FIG. First, the map display program 3 of the land price display system is started, and a map search screen 51 as shown in FIG.

In the map search screen 51, an input area for designating a "reference area" is provided. There, a district name to be referred to is selected and input (step 31).

Next, a "reference image" to be displayed on a map is selected by clicking with the input device 1, for example, a mouse (step 32). The "reference image" includes (1) a house map (attribute can be referenced), (2) a city planning map, and (3)
Each aerial photograph can be selected.

Therefore, for example, if "house map" is clicked and selected with a mouse, "." Is displayed at the top of the house map on the map search screen 51. In this state, by clicking the “image display” button on the map search screen 51 with a mouse, an execution instruction command is input from the input device 1. Then, the central processing unit 2 also searches for an address that matches the address entered from the “reference district” on the map search screen 51 and the “location and lot number” in the land price data table 9 (step 33). ], The coordinates (X,
Y) is obtained (step 34), and the house map data file 6 of the designated district is searched from the coordinates (X, Y) (step 35), and the house map is retrieved as shown in FIG. 5 (b). It is displayed on the screen 52 (step 36).

When a specific real estate in the house map on the search result screen 52, for example, a real estate for sale is specified by clicking with a mouse, the central processing unit 2 determines the coordinates (X, Y) of the specific real estate based on the data. , The same coordinates (X, Y) are searched from the land price data table 9 (step 3).
7) From the coordinates (X, Y), display the land price data 90 including the contents of the specific real estate transaction example as shown in FIG. 6 on the display device 5 (step 38). In this case, as shown in another display example of FIG.
It is also possible to generate a window 63 of a predetermined size and display land price data 90 including the contents of the trading example in this window 63.

In the above description, an example has been described in which a house map of a corresponding real estate is displayed by inputting the location of a “reference district”. However, a telephone number must be registered in the land price data table 9. When a "phone number" is input from the input device 1 by providing a telephone number input area on the map search screen 51, the central processing unit 2 reads the "phone number" from the land price data table 9. The data of the coordinates (X, Y) having the same telephone number is retrieved, and graphic data representing the shape of the road and the real estate is retrieved from the house map data file 6 based on the data of the coordinates (X, Y). , House map display device 5
To be displayed.

On the other hand, if "Aerial photograph" is selected in step 32, "House map" is NO in the flowchart of FIG. 4, "City planning map" is NO, and "Aerial photograph" is YES. The central processing unit 2 searches for a location that matches the location entered from the “reference district” on the map search screen 51 and the “location and lot number” in the land price data table 9 (step 43), and retrieves the “location and lot number”. The coordinates (X, Y) are obtained based on the coordinates (step 44), and the house map data file 6 and the aerial photograph data file 8 of the designated district are searched from the coordinates (X, Y) (step 45). The map and the aerial photograph are superimposed and displayed on the search result screen 52 as shown in FIG.
6). Also, for the "city planning map", the house map and the city planning map are superimposed and displayed on the search result screen 52 through steps 39 to 42 in the same manner as the "aerial photograph". In addition, when "city planning map" and "aerial photograph" are selected, they are displayed so as to be superimposed on the house map, but it is also possible to display each independently.
Further, if necessary, a "house map", a "city planning map", and an "aerial photograph" can be displayed in three layers.

[0018]

As described above, since the present invention is an all-digital map, it is possible to directly display a target screen by inputting a house number or a telephone number. Can perform analytical work. Further, since land price data can be displayed instantaneously, there is an advantage that a financial institution or a real estate-related business can always carry out operations after sufficiently grasping the accurate market price and the situation in the neighboring area. In addition, since it is possible to display an aerial photograph image that is information from the sky and also to display a city planning map, it is possible to accurately grasp the situation in the vicinity.
