Building Municipal Digital Twin Readiness: From UAV Base Mapping to Operational 3D Geoportal Infrastructure

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...

Augmenting City Models with Handheld LiDAR and 3D Gaussian Splatting for Inclusive Pedestrian Infrastructure Assessment

This study proposes a hybrid workflow integrating handheld LiDAR and 3D Gaussian Splatting within a CityGML-based semantic framework for accessibility assessment, contributing to the development of human-scale urban digital twins by integrating metric accuracy, semantic structure, and participatory evaluation for more...

Bridging Semantic Mesh, CityGML, and Gaussian Splatting for Urban Modelling and Visualization

A comparative framework linking LiDAR-derived CityGML, semantic mesh, 3D Gaussian Splatting, and Triangle Splatting within a unified urban modelling workflow is established, proposing a conceptual foundation for a unified 3D urban model capable of transforming consistently into semantic, surface-based, and radiance-bas...
