Abstract
Abstract. Historical artifacts living from the past until today exposed to many destructions non-naturally or naturally. For this reason, The protection and documentation studies of Cultural Heritage to inform the next generations are accelerating day by day in the whole world. The preservation of historical artifacts using advanced 3D measurement technologies becomes an efficient tool for mapping solutions. There are many methods for documentation and restoration of historic structures. In addition to traditional methods such as simple hand measurement and tachometry, terrestrial laser scanning is rapidly becoming one of the most commonly used techniques due to its completeness, accuracy and fastness characteristics. This study evaluates terrestrial laser scanning(TLS) technology and photogrammetry for documenting the historical artifacts facade data in 3D Environment. PhotoModeler software developed by Eos System was preferred for Photogrammetric method. Leica HDS 6000 laser scanner developed by Leica Geosystems and Cyclone software which is the laser data evaluation software belonging to the company is preferred for Terrestrial Laser Scanning method. Taking into account the results obtained with this software product is intended to provide a contribution to the studies for the documentation of cultural heritage.

The standard deviation for terrestrial laser scanning (TLS) data was obtained as 3.4 cm and the standard deviation for Photogrammetry was obtained as 2.9 cm
Summary
Photogrammetric methods are used for years to prepare databases (measured drawings and three-dimensional model) for maintenance and repair of historic buildings. These methods has enriched the development of laser scanners, detail and accuracy has been increased. Two different case studies were realized with both techniques and obtained results were compared by using statistical methods. These two methods are TLS and Photogrammetry techniques which are widely used in documentation of cultural heritage monument. We used Cyclone Software for TLS data and PhotoModeler software for Photogrammetry
