Abstract
The characteristic temporal backscattering signature of rice crop grow n under flooded condition was used to estimate rice acreage for a regi on in West Bengal, India. To date ERS-1 Synthetic Aperture Radar (SAR) data, one acquired within 30 days of transplantation and another afte r 30-40 days was found to be optimum for early estimation of rice acre age. The rice crop was found to be distinctly separable from forest, t ree vegetation, village/urban areas. Misclassification of rice was obs erved mainly with water, waterlogged areas and fallow fields.
