Global building footprint datasets show accuracy disparities, study finds

By PulseAugur Editorial · [2 sources] ·

A new study has evaluated the accuracy of four major global building footprint datasets: Global Human Settlement Layer (GHSL), Microsoft's TEMPO, The Global Building Atlas (GBA), and Overture. Using ORBITaL-Net as ground truth, the research found that GBA and TEMPO generally offered the highest accuracy, though performance varied by evaluation criteria. The study also highlighted significant accuracy disparities based on geographic location, population density, and income levels, with notable decreases in accuracy observed in Africa and Asia, as well as in high-density urban areas. AI

IMPACT Highlights limitations in current geospatial AI models, suggesting areas for improvement in data collection and model training for diverse regions.
