Google Open Buildings v3 Polygons Google Open Buildings

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. From Google Open Buildings FAQ (Open Buildings: Global Buil…) How complete and up-to-date is the data? The dataset freshness is determined by the availability of the high-resolution source imagery which we use to detect buildings. While we have tried to include the most recent images possible, particularly in populated areas, in some cases, the most recent image for some location was several years old or not available to us at all. To look at freshness for a particular area, the Historical Imagery function in Google Earth Pro shows the specific dates and imagery (check for imagery before the inference date given in the version history below). Furthermore, we have not processed imagery for the entire continent: to check whether a particular region has been included, the dataset explorer map above visualises all buildings in the dataset.
