Google Open Buildings v3 Polygons

The Open Buildings V3 Polygons dataset is a comprehensive geospatial resource offering outlines of 1.8 billion buildings derived from high-resolution (50 cm) satellite imagery. Covering regions across Africa, Latin America, the Caribbean, South Asia, and Southeast Asia, this dataset spans an area of 58 million km². Each building footprint is represented as a polygon, accompanied by a confidence score and a Plus Code for its center. While the dataset lacks information on building types or addresses, it serves critical applications, including population estimation, urban planning, disaster response, and climate studies. The initiative, originating in Ghana, highlights a strong focus on Africa with expanded coverage in other regions.
