🧰 Description techniqueBhanja et al. (2019) investigated the possibility of using Normalized Difference Vegetation Index (NDVI) as an indicator of groundwater storage is investigated, using . They used artificial neural network and support vector machine approaches and sand in-situ observations from groundwater wells. | 📏 Accuracy / ResolutionGood correlation (r> 0.6) between NDVI and groundwater levels in natural vegetation covered areas (i.e., forest lands, shrubs, and grasslands). | ||
🗺 Case studyIndia (> 15,000 wells). | |||
