URBR4Untransformed Reflectance Band Ratio 4

VegetationHyperspectralCitation Rank #117

Summary

The Untransformed Reflectance Band Ratio 4 (URBR4) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 1998; its source is cited as Bisun Datt (1998). Remote Sensing of Chlorophyll a, Chlorophyll b, Chlorophyll a+b, and Total Carotenoid Content in Eucalyptus Leaves. Remote Sensing of Environment, 66(2). https://doi.org/10.1016/s0034-4257(98)00046-7 .

Based on the latest citation data, this index is in the 65.5th percentile overall, ranking 117 out of 313 indices with citation data. Among the 41 indices published within two years of 1998, it ranks 32 (43.9th percentile). Within the vegetation application domain, it is in the 53.55th percentile and ranks 107 out of 211 indices with citation data. Among the 36 similarly aged vegetation indices, it ranks 31 (38.89th percentile).
