Abstract :
Hyperspectral imager suite (HISUI) is the Japanese next-generation earth-observing sensor composed of hyperspectral and multispectral imagers. Unmixing-based fusion of hyperspectral and multispectral data enables the production of high-spatial-resolution hyperspectral data. HISUI simulated imaging system combining two imagers was developed for verification experiments to investigate the feasibility and clarify the whole procedure of the hyperspectral and multispectral data fusion mission on HISUI. Airborne experiments are planned as simulation tests of HISUI higher-order products. The experimental results of the ground based observation showed the importance of the preprocessing and cross-calibration on the final quality of fused data, which contributes to the practical use of hyperspectral and multispectral data fusion.
