Application of Close-Range Photogrammetry for Post-Failure Reconnaissance of a Retaining Wall

Applicability of Photogrammetry for Inspection and Monitoring of Dry-Stone Masonry Retaining Walls

“…Photogrammetry is commonly used in the civil engineering field by state Departments of Transportation for large-scale mapping of transportation systems, construction sites, and topographical mapping, often using aerial images ( 15 – 17 ). Recently, photogrammetry has been used on smaller scale structures to obtain geometric measurements on bridges ( 18 – 20 ), capture movements of retaining walls in a series of experiments ( 7 , 21 ), and obtain estimates for the displacement of a retaining wall following an earthquake ( 22 ).…”
