Utilizing TVDI and NDWI to Classify Severity of Agricultural Drought in Chuping, Malaysia [PDF]
Agronomy, 2021 Agricultural drought is crucial in understanding the relationship to crop production functions which can be monitored using satellite remote sensors. The aim of this research is to combine temperature vegetation dryness index (TVDI) and normalized difference water index (NDWI) classifications for identifying drought areas in Chuping, Malaysia which has

Optimising NDWI supraglacial pond classification on Himalayan debris-covered glaciers [PDF]
Remote Sensing of Environment, 2018 The ability of medium-resolution (10–30 m) satellite imagery to delineate the size and persistence of ponds on debris-covered glaciers is a topic of recent interest as it has become apparent through the use of fine-resolution products that smaller ponds have often been neglected.

Specific features of NDVI, NDWI and MNDWI as reflected in land cover categories
Landscape & Environment, 2016 The remote sensing techniques provide a great possibility to analyze the environmental processes inlocal or global scale. Landsat images with their 30 m resolution are suitable among others for landcover mapping and change monitoring. In this study three spectral indices (NDVI, NDWI, MNDWI) wereinvestigated from the aspect of land cover types: water ...
