WCI2Wheat Canopy Index (Growth Stage 2)

VegetationMultispectralCitation Rank #312

Summary

The Wheat Canopy Index (Growth Stage 2) (WCI2) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2026; its source is cited as Ali Lotfi, Adam Carter, Thuan Ha, Mohammad Meysami, Kwabena Nketia, & Steve Shirtliffe (2026). Interpretable machine learning–Derived spectral indices for vegetation monitoring. Machine Learning with Applications, 24. https://doi.org/10.1016/j.mlwa.2026.100914 .

Based on the latest citation data, this index is in the 1.92th percentile overall, ranking 312 out of 313 indices with citation data. Among the 19 indices published within two years of 2026, it ranks 18 (31.58th percentile). Within the vegetation application domain, it is in the 1.9th percentile and ranks 210 out of 211 indices with citation data. Among the 13 similarly aged vegetation indices, it ranks 12 (30.77th percentile).
