Summary
The Normalized Difference Built-Up Index (NDBI) is a urban spectral index intended for multispectral sensing. It was introduced in 2003; its source is cited as Y. Zha, J. Gao, & S. Ni (2003). Use of normalized difference built-up index in automatically mapping urban areas from TM imagery. International Journal of Remote Sensing, 24(3). https://doi.org/10.1080/01431160304987 .
Based on the latest citation data, this index is in the 94.89th percentile overall, ranking 17 out of 313 indices with citation data. Among the 59 indices published within two years of 2003, it ranks 5 (93.22th percentile). Within the urban application domain, it is in the 100th percentile and ranks 1 out of 19 indices with citation data. Among the 1 similarly aged urban index, it ranks 1 (100th percentile).
