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.
