Summary
The Multi-Band Water Index (MBWI) is a water spectral index intended for multispectral sensing. It was introduced in 2018; its source is cited as Xiaobiao Wang, Shunping Xie, Xueliang Zhang, Cheng Chen, Hao Guo, Jinkang Du, & Zheng Duan (2018). A robust Multi-Band Water Index (MBWI) for automated extraction of surface water from Landsat 8 OLI imagery. International Journal of Applied Earth Observation and Geoinformation, 68. https://doi.org/10.1016/j.jag.2018.01.018 .
Based on the latest citation data, this index is in the 24.28th percentile overall, ranking 238 out of 313 indices with citation data. Among the 56 indices published within two years of 2018, it ranks 36 (37.5th percentile). Within the water application domain, it is in the 45.16th percentile and ranks 18 out of 31 indices with citation data. Among the 10 similarly aged water indices, it ranks 6 (50th percentile).

Default value2
Suggested values
- For negative index values assigned to water and non-water surfaces
- 1
- For positive index values assigned to water surfaces and built-up areas (greater values than this also deliver the same result)
- 5
- For positive index values assigned to water surfaces and negative to non-water surfaces
