However, as the utilization of weather information becomes generalized, weather information about a more detailed area is required.

For example, in the case of a solar power or a solar power generation system, it is possible to check the expected power generation amount based on the weather forecast of the region where the system is installed, thereby adjusting the angle of the power generation panel, The weather information service is used to determine the opening and closing of the ventilation openings of the installation equipment by using the weather information. Also, when the driving route of the vehicle is informed, the weather information service for the specific area, The types and the ranges of these are increasing.

Therefore, if weather information of a specific area is required, information of neighborhood forecast is utilized now, but actual information of neighborhood forecast is limited to city, and information is provided based on administrative district or jurisdiction, And it is difficult to standardize it because it has various shapes of administrative districts or statutory gates as a unit. When the neighborhood forecast information is expressed on a map, the information is averaged on the basis of the map, so the boundary between the regions is intermittent, It is impossible to confirm.

Therefore, it is necessary to provide effective regional weather information in order to solve such a problem and to support a combination with a variety of services.
