Web Resources Compiled For Terrain Modeling



Terrain modeling, the numerical study of ground-surface relief and pattern, has become integral to several subdisciplines of geophysics. Its two chief functions are topographic analysis and display. Both have been revolutionized by the computer processing of squaregrid arrays of terrain heights or digital elevation models (DEMs). Internet communication is vital to terrain modelers, who are dispersed worldwide in many occupations.
