  • The three-dimensional laser scan technology.also named the real-life scenery duplication technique,is another important technological revolution in surveying and mapping field after the Global Position System(GPS) technology.It has high efficiency and high precision.The three-dimensional point cloud data of the scanned object surface can be acquired by using the three-dimensional laser scan technology.Therefore,the technology can be used in gaining digital terrain models(DTM) with high accuracy and resolution.This paper will discuss the method of using the technology in quickly gaining DTM.A cut slope project is used as example.The method includes acquiring,aligning,coordinate adjusting,,de-noising and formating of digital elevation model.It is feasibility that the high accurate and resolution digital terrain model can be acquired using the technology within certain space.
