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 34.07th percentile overall, ranking 210 out of 317 indices with citation data. Among the 60 indices published within two years of 2021, it ranks 22 (65th percentile). Within the water application domain, it is in the 56.25th percentile and ranks 15 out of 32 indices with citation data. Among the 12 similarly aged water indices, it ranks 4 (75th percentile).
