Triangle network DTM building with concrete height points can be used for various aspects, e.g. generating contours, building surface model and calculating earthwork, etc. This paper introduces the applications of triangle network DTM in the earthwork computation of land leveling, river course excavating and embankment construction, and the volume computation of water areas.
