PROBLEM TO BE SOLVED: To provide a system capable of predicting the change of the Earth's surface, the underground, the sea, or the like, using inexpensive and past satellite images.SOLUTION: A change detection system 110 includes: a database unit 120 for ultra-small satellite images; an orthophoto unit 130; a database unit 150 for ultra-small satellite orthophoto images; an area image overlay unit 160; a memory 190 for area image accumulation; and an accumulated-image display unit 200. The system accumulates ultra-small satellite images Eirpa for several years or several tens of years, reports the change of the Earth's surface, the underground, the sea, or the like on the basis of the accumulated images, and makes a change occurring in the future to be estimated.SELECTED DRAWING: Figure 1 |
