Introduction

Buildings are among the most important elements represented in digital twins, urban planning systems and disaster risk management platforms. Accurate information on building location, size and height helps decision makers understand population exposure, assess infrastructure vulnerability, estimate economic losses and monitor urban development. Despite their importance, complete and consistent global building datasets have historically been difficult to obtain.
