APPLICABILITY OF SATELLITE REMOTE SENSING DATA FOR ANALYZING TEMPORAL CHANGES OF AGRICULTURAL LAND USE
Satellite remote sensing data has been expected as an effective source to produce quantitative information about land use in wide range of spatial scale. For characterizing the patterns of agricultural land use, a number of studies have been carried out to develop methods to discriminate land use types effectively as well as to produce land use maps of a specific site. Temporal changes of agricultural land use for wide area should be a target of analysis using satellite data, however, recently developed sensor data such as very high spatial resolution data or hyper-spectral data would not be suitable for the analysis owing to the constraints on timing of observation. The author attempted to develop methods to discriminate agricultural land use optimized for the cases of major grain crop production areas of China in collaboration with the Institute of Agricultural Resources and Regional Planning, Chinese Academy of Agricultural Sciences. The methods involved not only rather traditional way of classification but also newly developed way of fractional estimation applied to middle to coarse resolution data. Results showed the promising performance of existing satellite remote sensing data for producing temporal dataset of the specific agricultural land use.
