Abstract :
This paper outlines the operational feasibility of very early ERS SAR based acreage estimation of non-agriculture land (set-aside, fallow) and economically important crops in Europe, already during the winter season. To achieve this goal, a novel method for SAR time-series classification and interpretation has been developed. Results of a real-time ERS experiment are presented. Such results have been used for the first time in March 1995 to support the Rapid Estimates project of the European Union (EU). The results are compared to the first SPOT based estimates from this project obtained only two months later
