Summary
The Perpendicular Impervious Surface Index (PISI) is a urban spectral index intended for multispectral sensing. It was introduced in 2018; its source is cited as Yugang Tian, Hui Chen, Qingju Song, & Kun Zheng (2018). A Novel Index for Impervious Surface Area Mapping: Development and Validation. Remote Sensing, 10(10). https://doi.org/10.3390/rs10101521 .
Based on the latest citation data, this index is in the 21.09th percentile overall, ranking 248 out of 313 indices with citation data. Among the 56 indices published within two years of 2018, it ranks 41 (28.57th percentile). Within the urban application domain, it is in the 21.05th percentile and ranks 16 out of 19 indices with citation data. Among the 4 similarly aged urban indices, it ranks 4 (25th percentile).
