This study investigates the effect of topography in ancient city “Kerkenes” using Geographic Information Systems (GIS). Kerkenes, an Iron Age city located on a batholith in Yozgat province, Turkey, was chosen because of its exceptional size, short life and the availability of extensive data. Approximately seven kilometres of city wall in Kerkenes, including towers and seven gates, enclose 2.5 km². The research comprises topographic analysis and settlement data analysis. Elevation values collected by Global Positioning System (GPS) and 1:25000 scaled topographic maps are used to create and analyze elevation, slope and aspect maps. Basic statistics of the city wall, towers and gates are calculated and a procedure is then followed to examine the city wall, towers and gates to understand reasons for the line of the city wall, the uneven distribution of gates, the position of each individual gate, the positions and spacing of towers, and the water catchments. Advantages of the elevated site of Kerkenes for the foundation of a new capital within the region are demonstrated. The GPS data do not show statistically significant differences then the 1:25000 scaled topographic maps in regional scale, especially analyzing the elevation and slope data. Topographic analyses reveal that approximately 75% of the city wall coincides with the topographic divide which shows the city walls may serve both for urban water collection and for defence. City wall has divided into two as East section and West section by a north-south axis from the north end point of the city. There are 41 and 27 towers are detected on the West and East section, respectively. Towers on the West section are more closely spaced than the East section. There are also two and five gates in the West and East section, respectively. The East section of the city wall overlaps with the topographic divide only in the northeastern part. This situation can not be traced along the southeastern part of Kerkenes which may be the reason to include the strategically important two higher altitude areas (Kiremitlik and Kale) inside the city. The city wall in the West section, however, runs along the topographic divide which affects the number and the distribution of the towers.

Mineral mapping in Oymaağaç (Beypazarı)-Ankara) Granitoid by remote sensing techniques
Pekesin, Burcu Fatma; Toprak, Vedat; Department of Geological Engineering (2005)
The aim of this study is to extract information about mineral distribution and percentages of Oymaagaç granitoid (Beypazari-Ankara) by using remote sensing techniques. Two methods are applied during the studies which are spectral analysis and Crosta techniques. Spectral measurements are done for fresh and weathered samples collected at 32 locations. Mineral percentages are calculated using spectral mixture analysis for each sample by considering main, accessory and secondary mineral content of granodiorite....
Relationship between settlement location and morphological landform : a GIS method applied to Çankırı province
Sürmeli, Biricik Gözde; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2003)
This study aims to develop a method to investigate the relationship between settlement locations and the morphological landforms using geographical information systems (GIS). The method is applied to Çankiri province, a mountainous terrain, which is covered in seventy-seven sheets of topographic maps at 1:25.000 scale. Three databases are created and used in this study: 1) Settlement database comprising various topographic and landform attributes of 891 settlements, 2) Morphological landform database compos...
Integration of geophysical - geological data using geographic information systems
Şirinyıldız, Tunç; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2003)
This study attempts to integrate geophysical data with other spatial data using Geographic Information Systems (GIS). The study is carried out in a part of Galatean Volcanic Province, north of Ankara. Gravity, magnetic, topographic, rock type and volcanic eruption center data are the data layers used in the study. All data layers are converted to raster format with a grid spacing of 100 m. The first step in the analysis is the pair-wise analyses of all data layers. For the geophysical data, different layers...
Zircon typology and chemistry of the granitoids from central anatolia, Turkey
Köksal, Serhat; Göncüoğlu, Mehmet Cemal; Department of Geological Engineering (2005)
This thesis investigates the morphological, chemical and growth characteristics of zircon mineral in relation with the granitoid petrology. Physical and chemical variations recorded within zircon crystals during evolution of the Central Anatolian Granitoids are discussed. The thesis focuses on twelve granitoid samples from the Ekecikdag, Agaçören and Terlemez regions from western part of central Anatolia. These granitoids are differentiated into S- and H-type granitoids on the basis of field, petrographical...
A marginalized multilevel model for bivariate longitudinal binary data
Inan, Gul; İlk Dağ, Özlem (Springer Science and Business Media LLC, 2019-06-01)
This study considers analysis of bivariate longitudinal binary data. We propose a model based on marginalized multilevel model framework. The proposed model consists of two levels such that the first level associates the marginal mean of responses with covariates through a logistic regression model and the second level includes subject/time specific random intercepts within a probit regression model. The covariance matrix of multiple correlated time-specific random intercepts for each subject is assumed to ...
