The most powerful method of representing relief is to construct a mathematical model of the earth’s surface: a digital terrain model (DTM) or digital ellevation model (DEM). 3D modeling of urban areas objects is an expanding application. This paper aims to present haw to create a 3D model for a digital terrain model (DTM) or digital ellevation model (DEM) using low cost programs and technologies. 3D modeling of urban area using SketchUp softwere it is a reliable solution. The choice of data sources, terrain sampling techniques and interpolation method used in model construction are critical for the quality of the resulting DTM.
