    Evaluation of Laser Scanner Performance in Documentation of Historical and Architectural Ruins, a Case Study in Konya
    (Copernicus Gesellschaft Mbh, 2010) Korumaz, A. Güleç; Korumaz, M.; Dülgerler, O. N.; Karasaka, L.; Yıldız, F.; Yakar, M.
    Our country is rich not only with historical monuments also with many archeological places which especially belong to Rome, Seljukian and Ottoman period and before. Many late period historical monuments demolished because of destructive effects of wars, natural disasters, neglect. Conventional methods are not sufficient and sometimes they don't give good results in documentation of historical ruins because of the fact that the building or monument is structurally deformed. It is precedence needed to get 3D datum for research and documentation of these kinds of historical ruins. It gets more difficult to measure and draw these kinds of remains because of their deformation in their basic geometry and materials with destructive effects of years. Documentation with laser scanner is needed to determine destruction dimension, deformation, structural analysis and material measurement. This 3D documentation gives sensitive results in decision making process, restoration and restitution projects. In this study, it will be emphasized the importance of documentation of historical ruins and some examples scanned with laser scanner will be given from Konya-Turkey as example.

    Photogrammetric Measurement of the Meke Lake and Its Environment with Kite Photographs to Monitoring of Water Level to Climate Change
    (Copernicus Gesellschaft Mbh, 2010) Yakar, M.; Yıldız, F.; Metin, A.; Uray, F.; Ulvi, A.; Karasaka, L.; Mutluoğlu, O.; Şeker, D. Z.
    Over the last hundred years or so, the instrumental temperature record has shown a trend in climate of increased global mean temperature, i.e., global warming. Global warming and climate change have caused a decrease in lake waters, an increase in the sea level, and changes in streams and precipitation models and have started to show negative impacts on all aquatic organisms from plankton to mammals. Semi-arid and arid areas are particularly exposed to the impacts of climate change on freshwater. Unfortunately, due to global warming and the uncontrolled irrigation of farms, the "eye" of the lake has dried and rest of the lake is drying. This project has been started to get data about decreasing the water level and the physical changes in the Lake Meke. From September to March, the level of water has been determined. For this purpose, photogrammetric measurements have been done. Kite and remote-control camera has been used. With calibrated cameras and points on ground, the lake's surface has been evaluation photogrammetric software and got merged with present time map.
