OCVIOptimized Chlorophyll Vegetation Index

VegetationMultispectralCitation Rank #149

Summary

The Optimized Chlorophyll Vegetation Index (OCVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2008; its source is cited as M. Vincini, E. Frazzi, & P. D’Alessio (2008). A broad-band leaf chlorophyll vegetation index at the canopy scale. Precision Agriculture, 9(5). https://doi.org/10.1007/s11119-008-9075-z .

Based on the latest citation data, this index is in the 52.72th percentile overall, ranking 149 out of 313 indices with citation data. Among the 34 indices published within two years of 2008, it ranks 23 (35.29th percentile). Within the vegetation application domain, it is in the 38.86th percentile and ranks 130 out of 211 indices with citation data. Among the 16 similarly aged vegetation indices, it ranks 13 (25th percentile).
