Structural vulnerability assessment of heritage structures is a pivotal part risk mitigation strategy for preserving these valuable assets the nations. For this purpose, developing digital twins has gained much attention lately to provide an accurate model performing finite element (FE) analyses. Three-dimensional (3D) geometric documentation first step in twin, and various equipment methodologies have been developed facilitate procedure. Both aerial terrestrial close-range photogrammetry can be combined with 3D laser scanning geodetic methods documentation. The data processing procedure cases mostly focuses on detailed, models that used FE modeling. final surface or volumes are produced mainly by combining point clouds obtained from scanner photogrammetric methods. based geometries derived using software packages. As alternative, provided previous directly imported some In study, challenges strategies each investigated providing examples surveyed structures.
