Summary
Integrated digital surveys, leveraging 3D laser scanning and Structure from Motion (SFM) photogrammetry, offer powerful tools for documenting and diagnosing heritage vulnerabilities in urban blocks. A study of a Mexico City historic center block between Plaza Mayor and Templo Major demonstrated that these methods can effectively capture plastic deformations and masonry wall misalignments, providing critical data for conservation and restoration efforts. By analyzing building facades at an urban scale and individual architectural units at finer scales, researchers identified structural lesions, failure patterns, and collapse risks—key insights for preserving this UNESCO World Heritage Site, once the Aztec capital of Tenochtitlan.
