Summary
The New Built-Up Index (NBUI) is a urban spectral index intended for multispectral and thermal sensing. It was introduced in 2016; its source is cited as Priyakant Sinha, N. K. Verma, & E. Ayele (2016). Urban Built-up Area Extraction and Change Detection of Adama Municipal Area using Time-Series Landsat Images. International Journal of Advanced Remote Sensing and GIS, 5. https://www.researchgate.net/publication/306346676_Urban_Built-up_Area_Extraction_and_Change_Detection_of_Adama_Municipal_Area_using_Time-Series_Landsat_Images .
Based on the latest citation data, this index is in the 23.66th percentile overall, ranking 244 out of 317 indices with citation data. Among the 38 indices published within two years of 2016, it ranks 31 (21.05th percentile). Within the urban application domain, it is in the 26.32th percentile and ranks 15 out of 19 indices with citation data. Among the 5 similarly aged urban indices, it ranks 4 (40th percentile).
