The purpose of this study is to evaluate and to compare the results of bivariate statistical analysis conducted with three different data sets in Geographical Information Systems (GIS) based landslide susceptibility mapping applied to the Devrek region. The data sets are created from the seed cells of crowns and flanks, only crowns, and only flanks of the landslides by using 10 different parameters of the study area. To increase the data dependency of the analysis, all parameter maps are classified into equal frequency classes based directly on the percentile divisions of each seed cells data set. The resultant maps of the landslide susceptibility analysis indicate that all data sets produce acceptable results. In each seed cell data set analysis, elevation, lithology, slope, aspect and drainage density parameters are found to be the most contributing factors in landslide occurrences. The results of the three data sets are compared by Seed Cell Area Index (SCAI). This comparison shows that the crowns data set produces the most accurate and successful landslide susceptibility map of the study area.

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...
An approach for landslide risk assesment by using geographic information systems (gis) and remote sensing (rs)
Erener, Arzu; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2009)
This study aims to develop a Geographic Information Systems (GIS) and Remote Sensing (RS) Based systematic quantitative landslide risk assessment methodology for regional and local scales. Each component of risk, i.e., hazard assessment, vulnerability, and consequence analysis, is quantitatively assessed for both scales. The developed landslide risk assessment methodology is tested at Kumluca watershed, which covers an area of 330 km2, in Bartın province of the Western Black Sea Region, Turkey. GIS and RS t...
Exploring the relationship between the socio-economic structure and some topographic variables in Çankırı
Dilekli, Naci; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2004)
This study aims to develop a method to investigate the relationship between socio-economic status of village settlements and some topographic variables using geographical information systems (GIS) and spatial statistical methods. The study area is Çankiri province, a mountainous region that lays at the northeast of Ankara. 331 villages represented by areal units are used in this study. 195 variables are used to extract a single socio-economic status indicator. First, all the variables are divided under thre...
A GIS based spatial data analysis in Knidian amphora workshops in Reşadiye
Kıroğlu, M. Fatih; Tuna, Numan; Düzgün, Şebnem; Department of Geodetic and Geographical Information Technologies (2003)
The main objective of this study is to determine main activity locations and correlation between different artifact types in an archaeological site with geographical information systems (GIS) and spatial data analyses. Knidian amphora workshops in Datça peninsula are studied in order to apply GIS and spatial statistical techniques. GIS capabilities are coupled with some spatial statistical software and spatial data analysis steps are followed. Both point and area datasets are examined for the effective anal...
Dimension reduction for tree-structured data
Durak, Erdinç; Tural, Mustafa Kemal; İyigün, Cem; Department of Industrial Engineering (2021-9)
Statistical analysis of tree-structured data is one of the exciting research areas with expanding application areas. In classical data analysis, the data objects are points in the Euclidean space, whereas they are trees in the analysis of tree-structured data. The replacement of points in the Euclidean space with trees brings in additional complexity in data analysis and necessitates the use of dimension reduction techniques. In this study, we aim to develop dimension reduction techniques for tree-structure...
