Augmented Normalized Difference Water Index for improved surface water monitoring

Environmental Modelling and Software, 2021
Abstract We present a comprehensive critical review of well-established satellite remote sensing water indices and offer a novel, robust Augmented Normalized Difference Water Index (ANDWI). ANDWI employs an expanded set of spectral bands, RGB, NIR, and SWIR1-2, to maximize the contrast between water and non-water pixels.

A weighted normalized difference water index for water extraction using Landsat imagery

International Journal of Remote Sensing, 2017
Water extraction is one of challenging topics in studies on remote-sensing applications. Spectral profiles and experiments indicate that existing water indices often misclassified turbid water, sma...

Application of Normalized Difference Water Index for Vegetation Water Content Monitoring from MODIS Data

Advanced Materials Research, 2011
The needs for vegetation water content monitoring originates from forest fire assessment: Firstly, the vegetation water content affects the forest ignition point; secondly, it affects the spread rate if the forest is on fire. Based on the above reasons, the inversion of vegetation water content in Da Hinggan Ling region of China was studied, using the ...

The use of the Normalized Difference Water Index (NDWI) in the delineation of open water features

International Journal of Remote Sensing, 1996
The 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, 1996
The 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
