First, in step S31, an image of the sales complex is generated. To this end, the complex layout information 211 of the sales complex is used, and the complex layout information 211 includes the complex layout image of the sales complex, address information, information on the arrangement, information on the number of floors and lakes in each dong, and the planned construction of the complex. Various information on the pre-sale complex planned for construction, such as the total area and shape of the site, can be included.

The predicted map generation unit 221 generates a pre-sale complex image corresponding to the area of the pre-sale complex by using the plot of the pre-sale complex.

Specifically, an image corresponding to the total area of the sales complex is generated using the layout map image of the sales complex, and an appropriate scale for synthesizing the generated image on the actual map data is determined. In addition, one or more reference positions are determined on the image, and a Global Positioning System (GPS) coordinate value of the corresponding position is obtained.

The bottom line of each building is created in the image corresponding to the total area of the condominium, and identification information, number of floors, and lake information are determined for each building. At this time, if the bottom line of a specific building is rectangular, the area may be divided by the number of households in one floor from one side to the other, and then the household number (number of houses) may be determined in order. On the other hand, if the base line of a specific building is a square, it is possible to divide by half into a horizontal line and a vertical line, divide into quarters, and then assign a household number in a clockwise direction. At this time, the household number may be assigned using information indicating where the reference number 1 is.

In addition, the floor plan information for each level of the pre-sale complex is stored in association with the image of the pre-sale complex, but the link information of the corresponding floor plan is stored in each line household, and the location of the window or veranda in each floor plan is recognized and information about it is added. Can be saved.

In step S32, using the city planning information 212, an adjacent road to be newly built together with the construction of the sales complex is added to the sales complex image.

The predicted map generation unit 221 extracts information on a new road related to the pre-sale complex from the city planning information 212, and adds a road to be newly built to the pre-sale complex image by using the extracted new road information. It extracts road information in relation to the image corresponding to the total area of the pre-sale complex on the urban planning map and adds the image of the adjacent road to the image corresponding to the total area.

When the user selects a specific sales complex through the user terminal 100, an image of the selected sales complex is generated through the above process, and the image of the sales complex and an actual map are synthesized according to step S33, and the user terminal through the communication unit 240 Provided as (100).

In step S33, the actual map data of the area where the sales complex is to be located is obtained from the map data 213, and the sales complex image is overlaid on the actual map data based on the reference location information of the sales complex image to provide a predicted map including the sales complex. And display it.
