Urban Digital Twins (UDTs) are increasingly adopted to support evidence-based urban planning, municipal management, and municipal decision-making. However, many municipalities still lack the integrated geospatial infrastructure required to transform conventional mapping products into operational digital twin environmen...

Abstract. This study empirically evaluates the geometric accuracy of point cloud data acquired using an underwater lidar (ULi) system in a tropical shallow water environment. The field test was conducted in the tropical waters of the Seribu Islands, Indonesia, characterised by relatively low turbidity. Terrestrial lase...
