Summary
The Normalized Difference Nitrogen Index (NDNI) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 2002; its source is cited as Lydia Serrano, Josep Peñuelas, & Susan L Ustin (2002). Remote sensing of nitrogen and lignin in Mediterranean vegetation from AVIRIS data. Remote Sensing of Environment, 81(2-3). https://doi.org/10.1016/s0034-4257(02)00011-1 .
Based on the latest citation data, this index is in the 59.74th percentile overall, ranking 128 out of 313 indices with citation data. Among the 49 indices published within two years of 2002, it ranks 31 (40.82th percentile). Within the vegetation application domain, it is in the 46.45th percentile and ranks 115 out of 211 indices with citation data. Among the 41 similarly aged vegetation indices, it ranks 28 (36.59th percentile).
