Summary
The Normalized Difference Snow and Ice Index (NDSaII) is a snow spectral index intended for multispectral sensing. It was introduced in 2001; its source is cited as Xiangming Xiao, Zhenxi Shen, & Xiaoguan Qin (2001). Assessing the potential of VEGETATION sensor data for mapping snow and ice cover: A Normalized Difference Snow and Ice Index. International Journal of Remote Sensing, 22(13). https://doi.org/10.1080/01431160119766 .
Based on the latest citation data, this index is in the 30.67th percentile overall, ranking 218 out of 313 indices with citation data. Among the 41 indices published within two years of 2001, it ranks 36 (14.63th percentile). Within the snow application domain, it is in the 100th percentile and ranks 1 out of 10 indices with citation data. Among the 3 similarly aged snow indices, it ranks 1 (100th percentile).
