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 46.65th percentile overall, ranking 168 out of 313 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 32.7th percentile and ranks 143 out of 211 indices with citation data. Among the 11 similarly aged vegetation indices, it ranks 7 (45.45th percentile).
