The Development of the 5D Smart City Platform

The Development of the 5D Smart City Platform

In response to the future development and application requirements of smart cities and the Internet of Things, the National Center for Research on Earthquake Engineering (NCREE) has researched and developed a 5D smart city platform. The 5D smart city is a combination of a 3D city model, Taiwan satellite imagery, a digital elevation model (DEM), and time data (called a 4D model). The time data is transmitted through sensors to send digital information. Information is sent to the 5D smart digital space via the Internet. Using the 5G network, which can shorten the time required for synchronization between the 5D smart space and real-world data, the 5D digital space becomes a digital twin of the real world. The proposed platform was applied and verified in Zone C of the Shalun Smart Green Energy Science City. By using a 5D visualized platform, many types of information can be integrated for environmental monitoring, energy, images, or other sensing. The platform can be operated interactively in real-time and display characteristics at any viewing angle in the 3D scene. Furthermore, the platform improves the convenience of data access and establishes the relationship between simple data types, the geographical environment, and 3D scenes. This work can expand the value-added application of remote sensing technology in the field of smart cities and disaster prevention.
