In October 2008, CyArk, Leica-Geosystems, and SYSTOP travelled to Monte Alban in the Mexican region of Oaxaca to digitally record and archive major archaeological features at the site. Heritage managers at Monte Alban have faced numerous challenges in the preservation of the site including damage from earthquakes and erosion from visitor foot-traffic. The System IV structure was selected for digital preservation due to its exemplary features of the structural patterns found at the site, including a sunken courtyard and underground tunnels.
