VegetationMultispectralCitation Rank #6

Summary

The Soil-Adjusted Vegetation Index (SAVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1988; its source is cited as A.R Huete (1988). A soil-adjusted vegetation index (SAVI). Remote Sensing of Environment, 25(3). https://doi.org/10.1016/0034-4257(88)90106-x .

Based on the latest citation data, this index is in the 98.4th percentile overall, ranking 6 out of 313 indices with citation data. Among the 8 indices published within two years of 1988, it ranks 1 (100th percentile). Within the vegetation application domain, it is in the 98.1th percentile and ranks 5 out of 211 indices with citation data. Among the 8 similarly aged vegetation indices, it ranks 1 (100th percentile).
