List of spectral vegetation indices proposed for water detection.

Panel A lists the NDSIs tested in this work. For each NDSI is indicated the corresponding mathematical equation and the original reference. Panel B reports equations for combined index B2B6-EVI and B2B6-NDVI calculation. (*) original formulation for vegetation monitoring; (**) proposed for water mapping; (&) LSWI (Land Surface Water Index) is equal to the B2B6 MODIS index; ($) NDWI derived from SPOT-VGT data is equal to B2B6 MODIS index.
