FIG. 1 shows an example of an aerial photograph 100. The aerial photograph 100 is a photograph taken from a certain point in the air toward the ground surface, and includes an aerial photograph taken from an aircraft and a satellite photograph taken from an artificial satellite. As an example, assume that the aerial photograph 100 is an aerial photograph. The year in which the aerial photograph 100 was taken can be selected, and here, for example, the aerial photograph 100 at the time when the feed-in tariff system ends (also referred to as the "first time") is selected. The aerial photograph 100 is divided into a plurality of partial photographs 110, and one partial photograph 110 includes an area of, for example, 1.5 km x 2 km. Further, each partial photograph 110 is given identification information such as "0202".

The first point 270a to the fifth point 270e are collectively referred to as points 270, and these are information received from the reception unit 340. The second acquisition unit 350 acquires the coordinates of the designated point 270 from the coordinate information 260. This corresponds to obtaining the latitude and longitude of each point 270. Here, the coordinates such as latitude and longitude have a format such as CSV (comma-separated values), for example. Return to Figure 2.

Real estate information database 230 is connected to processing device 300 via a network such as the Internet. The real estate information database 230 stores location-related information of real estate. FIG. 4 shows the data structure of real estate location-related information in the real estate information database 230. In the real estate information database 230, information about the owner of the real estate, information about the address of the real estate, information about the contact information of the owner, and other information are shown for each coordinate. The contact information is, for example, a telephone number, but may also be an e-mail address or the like. Return to Figure 2.

That is, the third acquisition unit 360 acquires the real estate owner, the address of the real estate, the owner's contact information, and other information for each point 270. The third acquisition unit 360 may display the acquired information on the display device 210. FIG. 5 shows a screen displayed on display device 210. The display device 210 shows the point 270 on the map, and also displays the owner of the real estate for the point 270, the address of the real estate, the owner's contact information, and other information. Return to Figure 2. Based on this information, the user can urge the owner of the property where the fixed price purchase system will end to install a storage battery or the like by contacting the owner.

The third acquisition unit 360 may generate real estate address related information for the plurality of points 270 in a list format. Further, the third acquisition unit 360 may exclude previously generated address-related information of real estate from the generated address-related information of real estate. Address-related information of real estate generated in the past is, for example, address-related information of real estate generated one year ago, and this is information whose current time, first time point, and second time point were one year ago. It is. Through such processing, address-related information of real estate whose fixed price purchase system will newly end within the past year is specified. Based on this information, the user can urge the owner of the property whose fixed price purchase system will be newly terminated to install a storage battery or the like.
