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 53.31th percentile overall, ranking 149 out of 317 indices with citation data. Among the 35 indices published within two years of 2008, it ranks 23 (37.14th percentile). Within the vegetation application domain, it is in the 39.44th percentile and ranks 130 out of 213 indices with citation data. Among the 16 similarly aged vegetation indices, it ranks 13 (25th percentile).
