Google Earth Engine ——高分辨率 50 厘米卫星图像的建筑物轮廓数据集

This large-scale open dataset consists of outlines of buildings derived from high-resolution 50 cm satellite imagery. It contains 516M building detections across an area of 19.4M km2 (64% of the African continent).

For each building in this dataset we include the polygon describing its footprint on the ground, a confidence score indicating how sure we are that this is a building, and a Plus Code corresponding to the centre of the building. There is no information about the type of building, its street address, or any details other than its geometry.

Building footprints are useful for a range of important applications: from population estimation, urban planning and humanitarian response to environmental and climate science. The project being based in Ghana, the current focus is on the continent of Africa.

Inference was carried out during April 2021.
