This layer shows the distribution of water surfaces in Keur Massar (Dakar, Senegal) derived from Sentinel-2 imagery at 10 m spatial resolution. The satellite images were collected from Copernicus Browser (open access) on the 16th of April 2025. The Normalized Difference Water Index (NDWI) was calculated using the green and near-infrared bands of Sentinel-2. Water appears on the map starting from NDWI values of 0.01 (light blue), gradually increasing up to 0.38 (dark blue), representing areas with higher water presence. This layer serves as an input for a broader project, providing baseline information on water distribution to support the susceptibility assessment of illegal dumping sites. EPSG:3857
