Application of ALOS data for agriculture monitoring on East Asia

ALOS has three main sensors: PALSAR, AVNIR2, and PRISM. We examined the utilization of PALSAR and AVNIR2 for agriculture monitoring. L-band and multi-polarization SAR characterize PALSAR. We have investigated the capability of SAR applications for agriculture monitoring using RADARSAT data, and AVNIR was carried on ADEOS that operated from August 1996 to June 1997. There were very little AVNIR data for agriculture monitoring because the acquisitions of data were only during the wintertime in the northern hemisphere. We alternatively examined AVNIR abilities for frequent data acquisition with pointing function using SPOT/HRV data.
