Design of an Architectural Heritage Visualization System Based on Cesium

Abstract. Amid rapid global urbanization, architectural heritage preservation faces challenges like high resource consumption, low efficiency, and poor information visualization. Traditional methods, with heavy human, material, and financial investments, fail to fully present heritage details via archives, unable to meet large-scale, precise conservation needs. To address this, this paper develops a visual digital platform for architectural heritage protection through secondary development of the Cesium framework, integrating WebGIS, Node.js, Vue, and MySQL. The platform enables full-life-cycle management of heritage data, supports multi-source heterogeneous data upload and efficient management, and presents 3D visualized heritage models for an immersive experience. Innovatively incorporating GIS analysis (distance measurement, area calculation, coordinate picking), it provides data support for conservation decisions. It also allows uploading metadata (CAD drawings, videos, PDFs), forming a "3D model + materials" digital management system to enhance solution integrity. Verified with Xingcheng Ancient City as a case study, the platform offers a new approach for digital preservation and efficient management of architectural heritage, boosting the digitalization and technical application in heritage protection.
