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 88.33th percentile overall, ranking 38 out of 317 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 84.98th percentile and ranks 33 out of 213 indices with citation data. Among the 15 similarly aged vegetation indices, it ranks 3 (86.67th percentile).
