Summary
The Sealed Urban Index (SUI) is a urban spectral index intended for multispectral sensing. It was introduced in 2026; its source is cited as Ahmad Asad, Alessandra Capolupo, & Eufemia Tarantino (2026). A cross-sensor spectral index for soil sealing detection with improved impervious-bare soil discrimination. International Journal of Remote Sensing. https://doi.org/10.1080/01431161.2026.2715141 .
Based on the latest citation data, this index is in the 1.92th percentile overall, ranking 310 out of 313 indices with citation data. Among the 19 indices published within two years of 2026, it ranks 16 (31.58th percentile). Within the urban application domain, it is in the 5.26th percentile and ranks 19 out of 19 indices with citation data. Among the 1 similarly aged urban index, it ranks 1 (100th percentile).
