A Simple Technique for Modeling Terrains Using Contour Maps

In this paper we describe a simple modeling technique used to create precise and complex digital terrains models using contour maps. As a case study we use the terrain of the “Monte Albán” archeological site, located in the Mexican state of Oaxaca. We employ the technique with a simple contour map to obtain a realistic tridimensional terrain model that includes the four main hills of the site.
