Abstract	Exploring the construction of a county-level city real scene 3D digital twin foundation platform plays a positive role in promoting regional economic development and improving the quality of life for residents. In light of the lag in information construction within county-level cities, this paper proposes a requirement framework that includes basic geographic information services, smart city management, and data sharing and decision support. During the research process, the performance and user experience of the system platform are enhanced through key technologies such as multi-source heterogeneous data fusion technology and digital twin indoor and outdoor 3D visualization, achieving functions such as loading of 3D maps and models, real-time rendering, scene roaming, and interaction. Taking the Zhangjiachuan Geographic Information Visualization Platform project as an example, this study demonstrates the integration of real scene 3D technology with the needs of county-level cities. By constructing three subsystems for county overview, urban construction, and planning development, it provides government departments with an efficient, collaborative, and transparent decision support system, significantly enhancing decision-making efficiency and quality. © 2025 SPIE.
