Abstract
Time series Normalized Difference Vegetation Index (NDVI) data, computed from Advanced Very High Resolution Radiometer (AVHRR) data, were used in a pilot study to locate areas of rice cultivation in the United States of America (USA). The large size of rice fields and the relative phenological homogeneity of rice-growing regions in the US make them ideal sites for a pilot study. NDVI dynamics were examined using 16km global area coverage satellite data from 1988. Unsupervised classification was used to distinguish rice fields from other vegetation cover types. The technique was first used for California where contrast between irrigated and natural vegetation is the most pronounced. Identical methods were used to classify vegetation in China where the field size is much smaller and cropping season more extended.
