Summary
The Generalized Difference Vegetation Index (GDVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2014; its source is cited as Weicheng Wu (2014). The Generalized Difference Vegetation Index (GDVI) for Dryland Characterization. Remote Sensing, 6(2). https://doi.org/10.3390/rs6021211 .
Based on the latest citation data, this index is in the 47.95th percentile overall, ranking 166 out of 317 indices with citation data. Among the 28 indices published within two years of 2014, it ranks 12 (60.71th percentile). Within the vegetation application domain, it is in the 34.27th percentile and ranks 141 out of 213 indices with citation data. Among the 11 similarly aged vegetation indices, it ranks 7 (45.45th percentile).
