We utilized a UAV (unmanned aerial vehicle) or “drone” to collect digital photos and videos of the Main Plaza and surrounding areas. With the help of a supercomputer, we are processing these photogrammetric data to create a high resolution topographic maps. The final result will be the most accurate map ever made of Monte Albán’s Main Plaza. We are also creating 3D models of all the structures on the Main Plaza to carry out volumetric measurements and aid interpretation. See examples of the results of this work on the Visualizations page.
