 This study demonstrated the potential of combining optical and SAR data to improve crop mapping accuracy in West Africa. By integrating RapidEye and TerraSRx data, the authors were able to increase classification accuracy by 10% to 15%. Additionally, they found that the VD polarization was more effective at distinguishing between different crop types compared to the VH polarization. This suggests that the combination of optical and SAR data can be used to accurately identify and map crops in areas where there is limited access to satellite imagery or when cloud cover is present.
