Research on the application of 3D GIS technology in construction engineering surveying

Three dimensional geographic information system (GIS) technology provides accurate three-dimensional representation of terrain and building structures by integrating geographic data, software, and advanced analytical tools. This technology not only provides high-precision and high-resolution data capture capabilities, but also supports real-time data processing, making it particularly important in construction surveying. In construction surveying, the application scope of 3D GIS technology is extensive, covering the entire process from the initial stage of project planning to construction monitoring, and then to facility management in the later stage. This article comprehensively explores the various applications of 3D GIS technology in construction surveying, including determining the location of infrastructure, terrain analysis of construction sites, 3D monitoring of construction progress, accurate calculation of engineering quantity and material requirements, and facility management for later operation and maintenance.
