The Application of Modified Normalized Difference Water Index (MNDWI) by Leaf Area Index in the Retrieval of Regional Drought Monitoring [PDF]
Abstract. 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 vegetation coverage variation on the retrieval accuracy, the Leaf Area Index (LAI) is ...

Drought monitoring of forest vegetation using MODIS-based normalized difference drought index in Hungary [PDF]
In this paper, several spectral indices based on spectral reflectance data from the Terra satellite’s Moderate Resolution Imaging Spectro-radiometer (MODIS) sensor were evaluated in terms of their practical applicability for quantifying drought intensity

The remote sensing imagery of Normalized Difference Vegetation Index and Normalized Difference Water Index (NDVI & NDWI), and field explorations has given a richer understanding of the archaeological landscape of the Loralai district in Balochistan, Pakistan. A systematic survey was conducted by the first author in 2020, 2021, and 2022, examining a

Correlation of normalized difference water index and baseflow index in small island watershed landscapes [PDF]
Abstract The utilization of remote sensing data in the field of environmental hydrology is experiencing rapid progress. The Normalized Difference Water Index (NDWI) approach to transforming the water content of various land cover types and its implications for small island watersheds' hydrological characteristics is essential. NDWI is an
