BWDRVIBlue Wide Dynamic Range Vegetation Index

VegetationMultispectralCitation Rank #242

Summary

The Blue Wide Dynamic Range Vegetation Index (BWDRVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2007; its source is cited as Dennis W. Hancock, & Charles T. Dougherty (2007). Relationships between Blue‐ and Red‐based Vegetation Indices and Leaf Area and Yield of Alfalfa. Crop Science, 47(6). https://doi.org/10.2135/cropsci2007.01.0031 .

Based on the latest citation data, this index is in the 23rd percentile overall, ranking 242 out of 313 indices with citation data. Among the 40 indices published within two years of 2007, it ranks 38 (7.5th percentile). Within the vegetation application domain, it is in the 18.96th percentile and ranks 172 out of 211 indices with citation data. Among the 23 similarly aged vegetation indices, it ranks 23 (4.35th percentile).
