Understanding the condition, spatial arrangement, and changing patterns of vegetation cover holds significant scientific and economic importance. Satellite platforms offer a highly convenient means to study how vegetation reacts to atmospheric influences by gauging reflectance in the visible and near-infrared spectra. Given the numerous potential origins of environmental land cover variability, this study seeks to examine how vegetation cover influences water separation. This is achieved by identifying the Chlorophyll index (CIG) and Global Environmental Monitoring Index (GEMI) to enhance the vital safeguarding of water sector against the encroachment of excessive vegetation. To gain deeper insights into the impact of extensive vegetated areas, we have analyzed the CIG and GEMI within Swansea County, situated in Wales, United Kingdom. These emphasized indices are applied and their effectiveness is evaluated using geographic information systems and Remote Sensing technology. The outcomes of the CIG and GEMI analyses reveal that the indexes exhibit their lowest and highest values at (-1, 38) and (1.75105, -9.61413e+008) respectively. These findings indicate the presence of extensive vegetated regions with a substantial proportion of Chlorophyll emissions being reflected into the atmosphere. The dispersion of Chlorophyll concentrations across the environment implies a significant risk to the water sector, potentially resulting in severe shortages and the potential for future water scarcity. Elevated readings of the CIG and GEMI indicate extensive coverage of Earth's surface by vegetation, impacting the crucial water resources essential humanity. It is prudent to safeguard freshwater reserves and utilize it wisely to maintain its permanence.
