WaterMultispectralCitation Rank #213

Summary

The Sentinel-2 Water Index (S2WI) is a water spectral index intended for multispectral sensing. It was introduced in 2021; its source is cited as Wei Jiang, Yuan Ni, Zhiguo Pang, Xiaotao Li, Hongrun Ju, Guojin He, Juan Lv, Kun Yang, June Fu, & Xiangdong Qin (2021). An Effective Water Body Extraction Method with New Water Index for Sentinel-2 Imagery. Water, 13(12). https://doi.org/10.3390/w13121647 .

Based on the latest citation data, this index is in the 32.27th percentile overall, ranking 213 out of 313 indices with citation data. Among the 57 indices published within two years of 2021, it ranks 23 (61.4th percentile). Within the water application domain, it is in the 51.61th percentile and ranks 16 out of 31 indices with citation data. Among the 11 similarly aged water indices, it ranks 5 (63.64th percentile).
