In this paper, we started from the point of digital preservation and development of large-scale cultural heritage by combining the Global Positioning System (GPS) technology, the traditional single-point measurement with high speed, high-precision three-dimensional (3D) laser scanning technology. GPS and the traditional single-point measurement are used to establish control network to local landscape model into a union space coordinate system in order to study the distribution and evolution of its situation; while 3D laser scanning technology is used to get the accurate geometric description of the cultural heritage. By using post-processing software the point clouds data can be handled to establish the 3D visual model and two-dimensional line draw model which lay the foundation for heritage preservation and future research. The digital preservation of the 'Dr. Sun Yat-sen's Memorial Hall was presented as a case study in this paper to verify the advantages of digitization by 3D laser scanning.
