Starlab and ICACH have been using aerial and ground based methods for the topographical survey of an ancient watermill that is located in ktima Paphos in order to aid its architectural preservation.
We have elaborated low cost aerial photogrammetry (vertical and oblique imagery) and we we were able to extract from point clouds a digital elevation map and a contour map that are registered with ground control points (GCPs) acquired by a leica Total Station which is then been mapped in the Global Geodetic System (WGS 84). Ground Time-of-flight (TOF) terrestrial laser scanning is been used as well as structure from motion photogrammetric techniques (SfM) in order to reconstruct the monument and surrounding landscape in an accurate 3D virtual environment.
