Analysis of Dynamic Thresholds for the Normalized Difference Water Index
Photogrammetric Engineering & Remote Sensing, 2009 The normalized difference water index (NDWI) has been successfully used to delineate surface water features. However, two major problems have been often encountered: (a) NDWIs calculated from different band combinations [visible, nearinfrared, or ...

National Remote Sensing Bulletin, 2005 A modified normalized difference water index(MNDWI) has been proposed in this paper based on the normalized difference water index(NDWI) of Mcfeeters (1966), which uses MIR(TM5) instead of NIR(TM4) to construct the MNDWI. The MNDWI has been tested in the

The Application of Modified Normalized Difference Water Index by Leaf Area Index in the Retrieval of Regional Drought Monitoring [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 The vegetation coverage is one of the important factors that restrict the accuracy of remote sensing retrieval of soil moisture. In order to effectively improve the accuracy of the remote sensing retrieval of soil moisture and to reduce the impact of ...

Effectiveness of normalized difference water index in modelling Aedes aegypti house index
International Journal of Remote Sensing, 2012 The application of remotely sensed data to public health has increased in Argentina in the past few years, especially to study vector-borne viral diseases such as dengue. The normalized difference vegetation index (NDVI) has been widely used for remote sensing of vegetation as well as the brightness temperature (BT) for many years.
