JIRCAS Working Report
Technology of observing ground surface features using satellite borne sensors has been rapidly developed since 1970s for public purposes. Characterization of state of land use especially agricultural land use is one of expected target of application because it might be difficult to obtain reliable information for wide area by only ground level survey. Under this circumstance, Institute of Natural Resources and Regional Planning (INRRP) of Chinese Academy of Agricultural Sciences (CAAS) and JIRCAS started the collaborative research project adopting this technology in 1998 and continued until 2008. During the period, it was objected to develop a method to estimate sown area of staple crops in major producing areas, i.e. winter wheat in the Huang-Huai-Hai Plain and rice in the Heilongjiang Province. In either case study, it was revealed that high temporal resolution satellite data with wide spatial coverage was capable to monitor the sown area with considerable accuracy by means of introducing sub-pixel estimation techniques. The project also contributed the capacity building for young researchers of INRRP, who presently become leading researchers of this field in China, by providing opportunity to study in Japan.
