Use of Photogrammetry in Documenting Ruins/Traces of Cultural Heritage Not Surviving to the Present Day: A Comparative Case Study

Abstract Preservation of cultural heritage is our duty, but there are situations where the heritage cannot be preserved. In this case, if ruins and/or traces of building remain, they should be documented. The aim of this study is to recommend simple, quick and easily-applicable solutions for documentation studies of ruins of cultural heritage that was not preserved. In the extent of this study, a cultural heritage that could not preserve its existence till today but whose place was determined thanks to its traces is dealt with. Iasos Ancient City Theatre, which is the focus of the study, does not exist but its ruins should be documented. For this particular example, photogrammetry was used instead of traditional survey technique that is quite difficult to be applied. As a method, two different photograph-based programs made for photogrammetry were used and after comparing according to 6 criteria, advantages and disadvantages were presented. According to the findings, it can be said that there is no dimensional difference between two programs and both can be applicable.
