Nonuments, in other words hidden, erased, unwanted and otherwise forgotten monuments and built structures, are part of European Cultural Heritage. Cyprus is home to many Nonuments, such as Limassol's Carob Mill and other industrial old architectural buildings abandoned, or located in deserted areas and people do not have access to them. Significant effort to document them digitally by means of 3D photogrammetric techniques is under way by local and international partners. The workshop will introduce participants to various computational tools and techniques of image-based documentation of historic buildings, monuments or sites, as well as to relevant methodologies and software for managing the collected unstructured data that describe the scanned structures. In addition, the workshop will offer a field demonstration of how to use drones to document structures and buildings. The workshop is scheduled for the 7th and 8th of May 2018.
