VegetationMultispectralCitation Rank #144

Summary

The Soil-Adjusted Vegetation Index 2 (SAVI2) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1990; its source is cited as D. J. MAJOR, F. BARET, & G. GUYOT (1990). A ratio vegetation index adjusted for soil brightness. International Journal of Remote Sensing, 11(5). https://doi.org/10.1080/01431169008955053 .

Based on the latest citation data, this index is in the 54.31th percentile overall, ranking 144 out of 313 indices with citation data. Among the 15 indices published within two years of 1990, it ranks 13 (20th percentile). Within the vegetation application domain, it is in the 40.76th percentile and ranks 126 out of 211 indices with citation data. Among the 15 similarly aged vegetation indices, it ranks 13 (20th percentile).

Formula

N / (R + (slb / sla))

Bands

N

Near-Infrared (NIR).

R

Red.

Polarizations

No radar polarizations are used in this index.

Constants

sla

Soil line slope. N = sla * R + slb (only for soil pixels/measurements).

Default value1

slb

Soil line intercept. N = sla * R + slb (only for soil pixels/measurements).

Default value0

Reductions

No contextual reductions are used in this index.
