Abstract

The current study investigates the potential of ERS-1 SAR data for the mapping of rice fields and for rice crop monitoring. The selected study area is approximately 15 x 15 km in size and is located in the Kanchanaburi province, west Thailand. The rice growing area is irrigated, flat, homogeneously managed and has large individual fields of at least one hectare size. As regards rice fields' mapping, a digital classification on multi-temporal, speckle-filtered ERS-1 data images was carried out to determine rice fields' acreage. The classification accuracy for rice fields is 89 %. As regards rice crop monitoring, the radar backscattering coefficient of rice fields was related to various phenological parameters on a field-by-field basis, such as plant height, plant moisture content, stalk diameter, leaf size, occurrence of standing water and crop yield. It was found that there is a good correlation between plant height and backscattering and between crop yield and backscattering.
