NDWInsNormalized Difference Water Index with no Snow Cover and Glaciers

WaterMultispectralCitation Rank #262

Summary

The Normalized Difference Water Index with no Snow Cover and Glaciers (NDWIns) is a water spectral index intended for multispectral sensing. It was introduced in 2020; its source is cited as Dajiang Yan, Chang Huang, Ning Ma, & Yinsheng Zhang (2020). Improved Landsat-Based Water and Snow Indices for Extracting Lake and Snow Cover/Glacier in the Tibetan Plateau. Water, 12(5). https://doi.org/10.3390/w12051339 .

Based on the latest citation data, this index is in the 16.93th percentile overall, ranking 262 out of 313 indices with citation data. Among the 73 indices published within two years of 2020, it ranks 52 (31.51th percentile). Within the water application domain, it is in the 29.03th percentile and ranks 23 out of 31 indices with citation data. Among the 13 similarly aged water indices, it ranks 10 (30.77th percentile).
