Spatial Data Analysis (SDA) is relatively narrower and constitutes one of the areas of Spatial Analysis. Geographic Information System (GIS) offers a potentially valuable platform for supporting SDA techniques. Integration of SDA with GIS helps SDA to benefit from the data input, storage, retrieval, data manipulation and display capabilities of GIS. Also, GIS can benefit from SDA techniques in which the integration of these techniques can increase the analysis capabilities of GIS. This integration serves for disseminating and facilitating improved understanding of spatial phenomena. How SDA techniques should be integrated with GIS arise the coupling problem. The complete integration of SDA techniques in GIS can be applied without the support of GIS vendor when the free/libre and open source software (FLOSS) development methodology is properly followed. This approach causes to interpret the coupling problem in a new way. This thesis aims to develop a fully coupled SDA with GIS in FLOSS environment. A fully coupled SDA in free GIS software as FLOSS system is developed by writing nearly 13,000 line Python code in 2.5 years. Usage of this system has reached to nearly 1600 unique visitors, 3000 visits and 8600 page views in two years. As the current status of development in GIS is considered, it is unlikely in commercial market to have full coupled SDA techniques in GIS software. However, it is expected to have more SDA developments in proprietary GIS software in the near future as there is an increasing trend for requesting more sophisticated SDA tools.

Atmospheric correction and image classification on MODIS images by nonparametric regression splines
Kuter, Semih; Düzgün, H. Şebnem; Işık, Oğuz; Department of Geodetic and Geographical Information Technologies (2014)
In this study, two novel applications of nonparametric regression splines are introduced within the frame of remote sensing: (i) For the first time ever, atmospheric correction models are generated for moderate resolution imaging spectroradiometer (MODIS) images by using multivariate adaptive regression splines (MARS), and its recently introduced version, conic multivariate adaptive regression splines (CMARS). The obtained models are applied on the predefined test areas of twenty four different MODIS scenes...
Weighted multi-visibility analysis on directional paths
Şeker, Çağıl; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2010)
Visibility analysis is an important GIS tool that is used in a diverse array of disciplines ranging from earth sciences to telecommunications. Multi-visibility, as a cumulative type of visibility, combines many point-to-point results into a multi-value array. Points, lines, or areas can be used as sources or targets; and the combined values can be calculated in both ways. Through multi-visibility, a special 2.5D visibility value surface can be constructed over a digital elevation model. The effectiveness of...
Development of GIS-based national hydrography dataset, sub-basin boundaries, and water quality/quantity data analysis system for Turkey
Girgin, Serkan; Usul, Nurünnisa; Akyürek, Zuhal; Department of Geodetic and Geographical Information Technologies (2003)
Computerized data visualization and analysis tools, especially Geographic Information Systems (GIS), constitute an important part of today̕s water resources development and management studies. In order to obtain satisfactory results from such tools, accurate and comprehensive hydrography datasets are needed that include both spatial and hydrologic information on surface water resources and watersheds. If present, such datasets may support many applications, such as hydrologic and environmental modeling, imp...
Acceleration of line of sight analysis algorithms with parallel programming
Yılmaz, Gökhan; Sürer, Elif; Temizel, Alptekin (null; 2017-11-23)
Line of sight (LOS) analysis is a set of methods and algorithms to determine the visible points in a terrain with reference to a specific observer point. This analysis is used in simulations, Geographic Information System (GIS) applications and games. For this reason, it is important to have a capability to get results quickly and facilitate analysis in such a way that the interaction with the changing reference points is possible. Van Kreveld, R2 and R3 are the most frequently used algorithms in line of si...
Investigation of housing valuation models based on spatial and non-spatial techniques
Boza, Ertuğrul; Düzgün, H. Şebnem; Türel, Ali; Department of Geodetic and Geographical Information Technologies (2015)
The aim of this thesis is to develop hedonic housing valuation models based on spatial (SAR-simultaneous spatial autoregression and GWR - geographically weighted regression) and non-spatial (OLS - ordinary least squares) techniques, to compare the performances of these models and to investigate significant factors affecting housing value. The developed housing valuation models were tested at the Çankaya and Keçiören districts of Ankara province, Turkey. The results of the analyses revealed that significant ...
