About
Qijie Li is a geodetic engineer whose work bridges precision measurement and practical infrastructure monitoring. His primary research areas include precise trigonometric levelling, mobile surveying systems, and deformation monitoring for large-scale engineering projects. Li’s most impactful contribution is the development of the mobile precise trigonometric levelling (MPTL) system, which uses land vehicles equipped with modified measuring robots and position sensors to achieve high-accuracy height transfer without traditional static levelling. His 2016 paper on this method, cited 11 times, provides a rigorous mathematical model and error analysis, demonstrating how simultaneous reciprocal observations can significantly reduce atmospheric and instrumental errors. This innovation offers a faster, more flexible alternative for applications like railway and bridge construction, where precise elevation control is critical. Li’s work has been recognized for its practical value in geodetic engineering, making him a notable figure in advancing mobile surveying techniques. His research continues to influence the design of efficient, vehicle-based levelling systems that maintain accuracy while improving productivity in challenging field conditions.
