<P>PROBLEM TO BE SOLVED: To provide a land state estimation system capable of estimating the state of a corresponding land using one arbitrary index value which can be calculated for each pixel of a satellite image of each period among satellite images of three periods or more. <P>SOLUTION: A feature quantity showing the state of the corresponding land is estimated from an arbitrary positionally-corresponding index value, which can be calculated for each pixel, of satellite images of periods before and after some event (for example, a tsunami etc.) occurs and further at least one following period, i.e. three periods or more in total. <P>COPYRIGHT: (C)2013,JPO&INPIT |
