This study aims to assess vegetation health and drought conditions in Anantapur District, Andhra Pradesh, utilizing the Normalized Difference Vegetation Index (NDVI) and Soil-Adjusted Vegetation Index (SAVI) through geospatial technology. By analyzing Landsat 8 and Landsat 9 satellite imagery from the years 2013 and 2024, we investigate changes in vegetation cover and health over this period, correlating these changes with drought occurrences. NDVI and SAVI are employed to quantify vegetation density and health, accounting for soil brightness effects, which is particularly relevant in arid regions like Anantapur. The analysis reveals significant variations in vegetation health, highlighting areas of stress and resilience. The findings indicate a correlation between reduced vegetation indices and drought severity, providing insights into the impacts of climate variability on local ecosystems. This research contributes to understanding vegetation dynamics in response to environmental stressors and offers valuable information for sustainable land management and drought mitigation strategies in the region.
