Summary
The Built-Up Land Features Extraction Index (BLFEI) is a urban spectral index intended for multispectral sensing. It was introduced in 2019; its source is cited as Rafik Bouhennache, Toufik Bouden, Abdmalik Taleb-Ahmed, & Abbas Cheddad (2019). A new spectral index for the extraction of built-up land features from Landsat 8 satellite imagery. Geocarto International, 34(14). https://doi.org/10.1080/10106049.2018.1497094 .
Based on the latest citation data, this index is in the 24.29th percentile overall, ranking 241 out of 317 indices with citation data.
