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 65.93th percentile overall, ranking 120 out of 317 indices with citation data.
