The Current State of Collaboration between Digital Twin and OSM in Japan: A Case Study of Project PLATEAU
In recent years, 3D city models have become crucial for urban planning and research. Japan's Project PLATEAU has led the development of open 3D city models and point cloud data, with over 100 cities releasing Digital Twin data in CityGML format by February 2023. This talk explores the collaboration between Japan's Digital Twin initiatives and the global OpenStreetMap community. Since 2022, Japan's Digital Twin data, following the ODbL license, has been integrated with OpenStreetMap using specially developed tools. This integration aims to promote the global adoption of 3D city models, enhancing urban development through the synergy of Digital Twin technologies and OpenStreetMap.
