Here, four normalized difference water index (NDWI) variants, i.e., NDWI(860,970), NDWI(860,1240), NDWI(860,1640), and NDWI(1240,1640) are generated from the corn-oriented PROSAIL radiative transfer model. It is found that, instead of the linear relationship derived in previous studies, corn canopy water content (CWC) is best approximated as an ...

The use of the Normalized Difference Water Index (NDWI) in the delineation of open water features
International Journal of Remote Sensing, 1996The Normalized Difference Water Index (NDWI) is a new method that has been developed to delineate open water features and enhance their presence in remotely-sensed digital imagery. The NDWI makes use of reflected near-infrared radiation and visible green light to enhance the presence of such features while eliminating the presence of soil and ...

NDWI—A normalized difference water index for remote sensing of vegetation liquid water from space
Remote Sensing of Environment, 1996The normalized difference vegetation index (NDVI) has been widely used for remote sensing of vegetation for many years. This index uses radiances or reflectances from a red channel around 0.66 μm and a near-IR channel around 0.86 μm. The red channel is located in the strong chlorophyll absorption region, while the near-IR channel is located in the high

Monitoring vegetation and hydrological dynamics in semi-arid ecosystems is critical for understanding responses to climate variability and anthropogenic pressures. This study employs multi-temporal Landsat satellite imagery (1985-2024) to examine spatiotemporal changes in the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water

Determination of phenological dates in boreal regions using normalized difference water index [PDF]
Remote Sensing of Environment, 2005 Monitoring and understanding plant phenology is important in the context of studies of terrestrial productivity and global change. Vegetation phenology such as dates of onsets of greening up and leaf senescence have been determined by remote sensing ...

Drought trend analysis in a semi-arid area of Iraq based on Normalized Difference Vegetation Index, Normalized Difference Water Index and Standardized Precipitation Index [PDF]
Journal of Arid Land, 2021 Drought was a severe recurring phenomenon in Iraq over the past two decades due to climate change despite the fact that Iraq has been one of the most water-rich countries in the Middle East in the past.
