ATSAVIAdjusted Transformed Soil-Adjusted Vegetation Index

VegetationMultispectralCitation Rank #38

Summary

The Adjusted Transformed Soil-Adjusted Vegetation Index (ATSAVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1991; its source is cited as F. Baret, & G. Guyot (1991). Potentials and limits of vegetation indices for LAI and APAR assessment. Remote Sensing of Environment, 35(2-3). https://doi.org/10.1016/0034-4257(91)90009-u .

Based on the latest citation data, this index is in the 88.18th percentile overall, ranking 38 out of 313 indices with citation data. Among the 15 indices published within two years of 1991, it ranks 3 (86.67th percentile). Within the vegetation application domain, it is in the 84.83th percentile and ranks 33 out of 211 indices with citation data. Among the 15 similarly aged vegetation indices, it ranks 3 (86.67th percentile).

Formula

sla * (N - sla * R - slb) / (sla * N + R - sla * slb + X * (1 + sla ** 2.0))

Bands

N

Near-Infrared (NIR).

R

Red.

Polarizations

No radar polarizations are used in this index.

Constants

X

Negative abscissa of a reference point located on the soil line.

Default value0.08
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
