Static Terrestrial Laser Scanning (TLS): il caso del palazzo ottomano di Ahmed Bey a Costantina, Algeria

echniques to optimize the safeguarding and management of sites and monuments. The aim of this article is to illustrate the importance of 3D surveys acquired using a Terrestrial Laser Scanner (TLS). This study is the first to use this technique to valorize cultural heritage in Algeria. The approach was applied to the National Museum of Traditional Arts and Cultural Expressions, known as the Ahmed Bey’s Palace, a precious heritage from the Ottoman Empire in Constantine, Algeria. The point clouds from the TLS scan were processed through the Cyclone software (RCP file) to obtain a digital replica of the monument, which will be used not only to digitally archive Algeria's cultural heritage, but also to understand the current state of the building, its evolution and the various transformations carried out during the different periods of its history. In addition, the measurements from the TLS study were compared with those acquired from a traditional survey carried out previously. The accuracy of the TLS data highlights a significant margin of error with traditional surveys. TLS is accessible and easy to use, saving time and money and making it a feasible option for heritage sites.
