ABSTRACT
DTMs have found wide applications since their origin in the late 1950s, in various disciplines such as mapping, remote sensing, civil engineering, mining engineering, geology, geomorphology, military engineering, land planning, and communications (Catlow 1986; Petrie and Kennie 1990; Li and Zhu 2000; Maune et al. 2001). In this chapter, brief descriptions of various applications will be given.
