This study aims to analyze the density of mangrove vegetation in Simeulue Barat District, Simeulue Regency, to assess the condition of mangrove ecosystems in coastal areas. Mangroves play a crucial role in maintaining coastal ecological balance, protecting the coast from abrasion, and supporting the lives of marine life and coastal communities. This study uses a quantitative, descriptive-spatial approach based on remote sensing utilizing SPOT-7 satellite imagery. The data used are secondary data, including SPOT-7 Level-2 Surface Reflectance imagery from 2022, administrative boundary maps, and other supporting data. The analysis was carried out by calculating the Normalized Difference Vegetation Index (NDVI) value using the Near Infrared (NIR) and Red (RED) channels to identify the level of greenness and vegetation density. The resulting NDVI values were classified into vegetation density classes using the class interval method based on the Sturges formula to ensure proportional representation of data distribution, ranging from non-vegetation to very dense vegetation. The results show that the NDVI value in the study area ranges from -0,701408 to 0,725727, representing variations in land cover from water bodies to very dense mangrove vegetation. Based on the classification results, the Simeulue Barat District is dominated by very dense vegetation, indicating that the mangrove ecosystem is relatively well-maintained. This finding provides important spatial information for coastal management planning and mangrove conservation. This study recommends integrating NDVI with other vegetation indices and conducting field verification to improve the accuracy of future analyses
