An updated vector model of the coastline of the Republic of Cuba is presented, designed to improve the accuracy
and compatibility of thematic environmental mapping. Using high-resolution satellite data (European Space Agency, Sentinel-2)
and geospatial processing techniques, a detailed representation (1:25000) is generated, enabling applications in coastal
management, ecological conservation, and land use planning. The vector analysis (with 94% overall accuracy) provides an
estimate of the Cuban archipelago's surface area (109887.43 km2) very similar to the country's official figure. However, the
estimated length of Cuba's coastline (8517.67 km) differs from the 5746 km reported by the National Office of Statistics and
Information for over a decade.
