Summary
The Augmented Normalized Difference Water Index (ANDWI) is a water spectral index intended for multispectral sensing. It was introduced in 2021; its source is cited as Arash Modaresi Rad, Jason Kreitler, & Mojtaba Sadegh (2021). Augmented Normalized Difference Water Index for improved surface water monitoring. Environmental Modelling & Software, 140. https://doi.org/10.1016/j.envsoft.2021.105030 .
Based on the latest citation data, this index is in the 33.87th percentile overall, ranking 208 out of 313 indices with citation data. Among the 57 indices published within two years of 2021, it ranks 20 (66.67th percentile). Within the water application domain, it is in the 54.84th percentile and ranks 15 out of 31 indices with citation data. Among the 11 similarly aged water indices, it ranks 4 (72.73th percentile).
