Plant physiological indices for Euryale ferox Salisb. an endangered aquatic plant from Gyeongsan Province, were analyzed in this study. The NDVI (Normalized Difference Vegetation Index) was highest at 0.820 in Dongguji and lowest at 0.592 in Dongjaji; the SR (Simple Ratio) index was highest at 10.240 in Dongguji and lowest at 4.312 in Dongjaji; and the PRI (Photochemical Reflectance Index) was highest at 0.039 in Dongguji and lowest at −0.036 in Dongjaji. The CRI1 (Carotenoid Reflectance Index 1) index was in Sahwaji and Waji at 8.881 and 12.988, respectively, and the CRI2 (Carotenoid Reflectance Index 2) index was highest at 7.889 in Sahwaji and lowest at 11.889 in Dongjaji.
