Summary
The Simple Ratio (800 and 550 nm) (SR2) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1993; its source is cited as C. BUSCHMANN, & E. NAGEL (1993). In vivo spectroscopy and internal optics of leaves as basis for remote sensing of vegetation. International Journal of Remote Sensing, 14(4). https://doi.org/10.1080/01431169308904370 .
Based on the latest citation data, this index is in the 61.02th percentile overall, ranking 123 out of 313 indices with citation data. Among the 23 indices published within two years of 1993, it ranks 21 (13.04th percentile). Within the vegetation application domain, it is in the 47.39th percentile and ranks 112 out of 211 indices with citation data. Among the 23 similarly aged vegetation indices, it ranks 21 (13.04th percentile).
