Overview of the Top-Level Design and Practice of the ReS3D China

Abstract. This paper explores the construction of 3D Real-Scene China (ReS3D) as a pivotal element of national new infrastructure, aiming to establish a unified spatio-temporal foundation for Digital China through realistic, three-dimensional, and time-sequenced spatial data. This initiative supports the digital economy, digital governance, and Beautiful China objectives. From a top-level design perspective, the paper outlines the goals, tasks, and technical pathways of 3D Real-Scene China, highlighting the strategy of "building while using, promoting construction through application." However, challenges persist, including complex data acquisition and processing technologies, limited inter-departmental collaboration, and inadequate mechanisms for data standardization and sharing. By analyzing the synergy between top-level design and local practices, the paper examines the potential and challenges of 3D Real-Scene China in advancing high-quality development, providing insights for optimizing its construction trajectory.
