Multi-Scalar Urban Digital Twin Design: Architecture and OpenUSD Standards Based Methodology


December 28, 2023

DOI : 10.56831/PSEN-04-100


Digital twins have become indispensable tools in urban planning, providing dynamic and interactive portrayals of urban landscapes. This paper presents an innovative perspective on urban digital twin design, placing a pronounced emphasis on a multi-scalar framework that captures the intricate dynamics of urban systems across macro, meso, and micro scales, enriched by the concept of varying levels of detail. The proposed architectural model is rooted in OpenUSD standards, harnessing the Universal Scene Description format to amplify interoperability, facilitate seamless data exchange, and enable nuanced capture of urban visual features. Our exhaustive methodology addresses the constraints observed in existing urban digital twin frameworks and showcases the effectiveness of our approach through practical implementation in real-world urban settings. The outcomes underscore the critical role of multi-scalar representation and the integration of OpenUSD standards in propelling the capabilities of urban digital twins, thereby fostering more enlightened and responsive urban planning.
