Claim 6:
7. A non-transitory computer readable medium having computer-executable instructions that, upon execution of the instructions by a processor of a computer, cause the computer to: acquiring statistical data for a predetermined range of region, the region being divided into a plurality of sections on a basis of latitude and longitude, the statistical data being acquired for each section, the statistical data including first statistical data acquired for some or all of a plurality of first sections obtained from the region divided by a first area and second statistical data acquired for some or all of a plurality of second sections obtained from the region divided by a second area; generating a first statistical image and a second statistical image, the first statistical image representing a first statistical value as a pixel value corresponding to a position of each first section, the first statistical value being a statistical value for the first section indicated by the first statistical data, and the second statistical image representing a second statistical value as a pixel value corresponding to a position of each second section, the second statistical value being a statistical value for the second section indicated by the second statistical data; determining whether each pixel of the first and second statistical images has a pixel value indicating the statistical value; generating a mask image, the mask extracting, if one statistical image of a pixel of the first statistical image and a pixel of the second statistical image corresponding to a position of that pixel does not have a pixel value indicating the statistical value, a pixel not having a pixel value indicating the statistical value or other pixel; and generating, on a basis of the first statistical image, the second statistical image, and the mask image, a third statistical image in which a pixel value of a pixel not having a pixel value indicating the statistical value is complemented with a pixel value of the other statistical image.
