Summary
The Normalized Distance Red SWIR (NDRS) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2021; its source is cited as Langning Huo, Henrik Jan Persson, & Eva Lindberg (2021). Early detection of forest stress from European spruce bark beetle attack, and a new vegetation index: Normalized distance red & SWIR (NDRS). Remote Sensing of Environment, 255. https://doi.org/10.1016/j.rse.2020.112240 .
Based on the latest citation data, this index is in the 42.9th percentile overall, ranking 183 out of 317 indices with citation data. Among the 60 indices published within two years of 2021, it ranks 15 (78.33th percentile). Within the vegetation application domain, it is in the 30.05th percentile and ranks 151 out of 213 indices with citation data. Among the 35 similarly aged vegetation indices, it ranks 12 (71.43th percentile).
