Abstract
An object of the invention is to provide a method and an apparatus for producing land-surface image data, which can correct, with relatively high accuracy, cloud image data included in satellite image data into land-surface image data that would emerge in the absence of a cloud. Geostationary satellite image dataof a predetermined time at a production standard date is obtained, and a determination whether each pixel is a pixel reflecting a land surfaceor a pixel reflecting a cloudis made to set partial image dataand a missing region. Then, processing is repeated by sequentially adding another imaging date and time according to a predetermined priority until the missing regionis filled up with the pixel determined to be the pixel reflecting the land surface, thereby producing interpolated image datato produce the land-surface image data. The pixel is determined to be the pixel reflecting the land surfacefrom a pixel value in the another imaging date and time that is determined to be data having a close temporal relevance in a relationship between a solar position and the predetermined time of the production standard date.
