Özet: Terrestrial laser scanning, one of the main subjects of geomatics engineering, is an important technological development that is frequently used in many different studies including industrial design studies, mining and infrastructure studies, modeling and design of cities, architectural restoration and documentation studies etc. In this study, it is aimed to modelling and documenting the architectural Science History Collection (Historical Seismology Building) building located in the Kandilli Campus of Boğaziçi University by using a terrestrial laser scanning tool. For this purpose, before the study, a reconnaissance survey was performed around the building and the positions of the terrestrial laser scanner and the stations were homogeneously distributed in the study area to minimize the error that may arise when combining point clouds. The Historical Seismology Building was measured by terrestrial laser scanning device from 17 stations and a 3D model of the building was produced from the obtained point clouds. All scanned stations of the point clouds were adjusted and errors of 3.7 mm, 1.5 mm and 4.1 mm were found in horizontal direction, vertical direction and average length, respectively. This error was found to be within the error limits. This study is just a start for the university, and it is aimed to apply terrestrial technology in the studies of documenting different cultural assets within the campuses of the university, especially Kandilli Campus.
