SEVIShadow-Eliminated Vegetation Index

VegetationMultispectralCitation Rank #268

Summary

The Shadow-Eliminated Vegetation Index (SEVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2019; its source is cited as Hong Jiang, Sen Wang, Xiaojie Cao, Chenghai Yang, Zhaoming Zhang, & Xiaoqin Wang (2019). A shadow- eliminated vegetation index (SEVI) for removal of self and cast shadow effects on vegetation in rugged terrains. International Journal of Digital Earth, 12(9). https://doi.org/10.1080/17538947.2018.1495770 .

Based on the latest citation data, this index is in the 15.34th percentile overall, ranking 268 out of 313 indices with citation data. Among the 68 indices published within two years of 2019, it ranks 57 (17.65th percentile). Within the vegetation application domain, it is in the 14.22th percentile and ranks 182 out of 211 indices with citation data. Among the 34 similarly aged vegetation indices, it ranks 26 (26.47th percentile).
