Post-Intervention 3D Scanning at Cerro Sechín, Peru

As a complementary final documentation of the project, WMF Peru performed a 3D scanning of Cerro Sechín using orthophotography and LiDAR technologies. The activity included a reconnaissance of the area; the identification of points and location with GPS of the polygon; tests of drone and LiDAR equipments; general documentation of the site’s polygon using LiDAR  Emesent Hovermap (at Cerro Sechín hill and main building); and documentation of the main building and carved stone monoliths using orthophotography with drone Phantom 4 RTK and Matrice 300 RTK.
 
Through this documentation process, consolidations on its stone slabs, interventions at the tops of walls, and gap-filling treatments were verified after recent rains impacted the region. The documentation confirmed that all elements are stabilized and in good condition, without changes in color or signs of erosion after grouting was applied on top of walls or in joints.

The work at Cerro Sechín was possible thanks to the U.S. Ambassadors Fund for Cultural Preservation (AFCP), the U.S. Embassy Lima, the Tianaderrah/Nellie and Robert Gipson Foundation, Nor Oil SAC, the Cerro Sechín Archaeological Project and the Regional Cultural Office of Áncash.
