    Documentation of Necatibey Boulevar in Izmir With Close Range Digital Photogrammetry
    (Izmir Institute of Technology, 2009) Saygı, Gamze; Turan, Mine
    This study explores a methodology for documentation and visualization of historic streetscapes in the context of preservation discipline, and focuses on the potential of rectified image mosaics within the context of single image rectification option of close range digital photogrammetry. Necatibey Boulevard which is situated in the urban retail core of İzmir, is selected as the case study of this thesis for testing the proposed methodology. Comparison with conventional ways of documenting historical street facades is also provided. The selected streetscape and its surrounding consist of commercial buildings dating 1920s, and then 1950s onwards. Especially the ones constructed in 1920s are valuable with their architectural characteristics; however, some alterations and conversions are identified on the facades because of the unconscious usage and the change of the lifestyles. Documenting the street facades of this mentioned urban site is a prerequisite for taking preservation decisions. Within the objective of the thesis, rectified image mosaic showing the present conditions of the Necatibey Boulevard and thematic representations prior to conservation decisions are produced. The produced methodology can be easily applied for documentation of historic facade series prior to conservation decisions of street rehabilitation projects. The comparison of the rectified image mosaic with 2D elevation have pointed out that the former is a realistic way for the representation of architectural details, colors and textures. The changes of the street in time are also better perceived. Moreover, the production of the digital image mosaics of the historic street facades can also be useful for production of urban databases.

    Documentation of a Historical House With Close Range Digital Photogrammetry
    (Izmir Institute of Technology, 2008) Akbaylar, İpek; Turan, Mine
    This study aims to document the original architectural characteristics, alterations and damages of a historical house by combining the digital photogrammetric techniques with the mapping concepts of architectural conservation so that an architectural conservation project can be guided. The proposed documentation is carried on the entrance façade of a 19th century house located in the urban conservation site of Alaçatı, ..zmir, Turkey. The Demiral House has conservation priority among the other listed houses because of its vacant state and damages.Analytic recording of the façades of the historical houses in Alaçatı can be made fast with the rectification option of close range monoscopic softwares. A calibrated digital camera and a total station are the other tools used in this process. The colored thematic maps prepared are accurate enough for 1/50 scale analysis and they possess the qualitative information on the photographs. After it is checked that the threedimensional measurements defining the general geometry overlap with the 1/50 scaled rectified image mosaic, the details concerning the deteriorations are decided to be drawn to the scaled elevation drawing from this mosaic.This study has proposed a contemporary documentation technique so that architect-conservators can easily adapt in their conservation projects. When compared to the frequently applied documentation techniques like hatching on scaled twodimensional elevation drawings, it takes shorter time to prepare the proposed mapping method on rectified image mosaic. The architect-restorer has also the chance to examine many constructional details on the scaled rectified image mosaic. The end results are more realistic. Keywords: Architectural conservation, Close range, Rectification, Mapping, Alaçatı.

    Photogrammetric Evaluation Options for Ancient Structures in Hypokremnos, Pagos, Paradiso and Nysa
    (Izmir Institute of Technology, 2013) Uygun, Funda; Turan, Mine
    This study has focused on 3D reconstruction of ancient monuments based on photogrammetric documentation. The aim of the thesis is to search the limits of automatic and manual photogrammetric evaluation and modeling processes for interpreting of morphologic characteristics of ancient monuments with different geometries, positions, site conditions, and documentation necessities. Emphasis is made on documentation of historical structural characteristics for their conservation aim. In the methodology of the study, three parameters effecting the quality of the photogrammetric documentation are considered. First parameter is the type of the photogrammetric evaluation software. Manual photogrammetric software; Tgi3D SU and two automated photogrammetric software; Photosynth and Autodesk 123D are used in the study. Variation in the form, size and displacement of the monuments has been defined as the second parameter. In turn, four ancient monuments which have different characteristic features are studied; Hypokremnos Viaduct, Pagos Cistern, Paradiso Aqueduct and Nysa Library. Type of the 3D model and scale of documentation is defined as the last parameter of this thesis. A three dimensional way of documenting structural characteristics of ancient monuments is searched. 1/50 and 1/130 is selected for automatic documentation techniques as documentation scale, while 1/20 scale is selected for manual documentation technique. This study proves that documentation of structural characteristics of ancient structures may be realized in a successful way with manual photogrammetric technique. The 3D model is much more satisfactory compared to those based on automatic photogrammetric techniques in terms of accuracy control, level of geometric detail and documentation of surfaces. Consequently, while automatic evaluation is insufficient for providing data leading to structural evaluation, manual photogrammetric evaluation enriches the content of documentation of a historical structure. Structural system detail and 3D model to be used in intervention decisions of structural system can be produced with the help of the manual photogrammetric technique without the necessity of any further documentation.
