Outline of Final Research Achievements

Space and air-borne remote sensing images of the agricultural fields in Sendai Plain damaged by tsunami caused by the 2011 Great East Japan Earthquake were analyzed. Temporal change from just after to half a year later the disaster on the flooded area were extracted. Yearly change of reconstruction process were shown on the map. Some of the reconstructed fields have been problematic owing to the variability in crop growth caused by differences in soil fertility and other factors. This variability was recognized using high resolution satellite imagery. Agricultural parcel vector data were used for the precise analysis.
