Use of synthetic aperture radar data for the determination of normalized difference vegetation index and normalized difference water index

This study was based on analysis of Sentinel-1 (SAR) data to estimate the normalized difference vegetation index (NDVI) and the normalized difference water index (NDWI) during the period 2019 to 2020 in a region with a range of different land uses.
