 This research aims to produce crop maps for small-sized parcels in areas with abundant rainfall using Landsat-8 and HJ-1 CCD satellite data, masking out non-vegetation areas, and extracting four key phenological metrics from time series normalized difference vegetation index curves. The results show an accuracy of 92% when compared with highly accurate but limited ZY, three images, and matched up to 80% to statistical crop areas.
