Article Citation - WoS: 7Citation - Scopus: 7Impacts of Planners' Different Viewpoints on Optimum Land-Use Allocation(Routledge, 2013) Türk, Ersin; Çelik, Hüseyin MuratDevelopment of different viewpoints/perspectives in the planning process and discussion of their empirical results will allow creation of "better land-use plans". In this sense, one of the deficiencies met by the land-use planners is lack of decision support system that can analyse the empirical results of different viewpoints analytically. The aim of this study is to analyse impacts between planners' different viewpoints and the optimum land-uses allocation empirically and analytically. The study uses a generalized land assignment model formulated by Hanink and Cromley (1998) [Land-use allocation in the absence of complete market values, Journal of Regional Science, 38(3), pp. 465-480] that integrates the geographical information systems with multi-criteria decision-making techniques in Cesme/Izmir in Turkey. The study results indicated that the model is very useful to analyse impacts between planners' viewpoint and optimum land-use allocation.Article Citation - WoS: 6Citation - Scopus: 7Determination of Optimum Environmental Conservation: Using Multi-Criteria Decision-Making Techniques(Taylor and Francis Ltd., 2011) Çelik, Hüseyin Murat; Türk, ErsinThe type and degree of conservation areas in Turkey legally dictate the kind of land uses that can and cannot take place in a conservation area. Thus, the conservation scheme is one of the most important criteria in designing an urban land-use plan. The aim of this study is to analyse the effects of various conservation decisions on land-use allocation holding everything else constant. This study uses a land-allocation mathematical programme formulated by Hanink and Cromley [(1998) Land-use allocation in the absence of complete market values, Journal of Regional Science, 38, pp. 465-480] that integrates the geographical information systems with a generalized assignment problem to determine an optimum level of conservation scheme in Cesme/Izmir, a coastal resort in Turkey. The findings state that the proposed technique is indeed very useful and promising to answer diversified practical issues on a more rational basis.Article Citation - WoS: 22Citation - Scopus: 28The Impact of Rail Transit Investment on the Residential Property Values in Developing Countries: The Case of Izmir Subway, Turkey(Emerald Group Publishing Ltd., 2006) Çelik, Hüseyin Murat; Yankaya, UğurPurpose The purpose of this paper is to test whether the rail transit investment in Izmir, Turkey has had positive valuation impacts on the surrounding residential properties, and to estimate the value of travel time using relevant parameters. Design/methodology/approach The necessary data were collected via a survey including all real-estate agents in the area. To test the research question, the Hedonic Price Model (HPM) is used as the research technique. The obtained parameters are also used to estimate the value of travel time. Findings The findings of the models has indicated that the proximity to rail stations was valued at $250-300 per meters, and the value of travel per hour was $1.47-1.83 on average. Research limitations/implications These findings should be checked with more consistent database using transaction process, and the mortgage loan rate which was not legislated at the time of study. Practical implications Until a mortgage loan rate is registered in turkey, the estimated parameters can be used in the cost-benefit analysis of rail transit investments in Turkey. Originality/value The theoretical premise that “any improvement in accessibility will be capitalized into the land values” is tested one more time in a developing country case whose urban environment is substantially different from those of the developed world, especially the North American cities. Furthermore, a new methodology using the HPM parameters is also suggested to estimate the value of travel time.Master Thesis Modeling Retail Structural Change of Izmir Using a Dynamic Spatial Interaction Model(Izmir Institute of Technology, 2004) Kompil, Mert; Çelik, Hüseyin MuratRetailing, one of the most important sectors in all developed economies, has always been the prominent element of urban morphology, and evolves as the city evolves and expands. The last two decades have witnessed considerable changes in retailing throughout developed countries such as, the emergence of new store formats, the increased prevalence of retail chains, the development of out-of-town and edge-of-town retail parks accompanying with the changing conditions of globalized world. Since the sector has undergone major changes in scale, organization, and geography, the urban spaces have been the scene of these ongoing changes.Under the influence of global economic transformation after 80's, there have also been dramatic changes in retail industry and retail environment in Turkey. Despite the sector in Turkey is still dominated by large number of small, independent, and single location retailers, market share and spatial prevalence of large-scale retailers' have been increasing rapidly. Especially in major cities of the country, both international and domestic retail chains have been imposing a transformation and restructuring the urban retail environment. Among all the areas of retailing, food retailing stands out as having seen the most profound changes in Turkey. With respect of this, the study explores the spatial consequences of the structural change of food retailing system in Izmir. The prevalence of large-scale food retailers such as hypermarkets and supermarkets has negative effects on the survival of many small-independent retailers. The increasing competition has led to a changing retail structure with the dominance of organized retailers where the number of small-scale retailers and their total size are decreasing. As the trends continue, this will have important and unpredictable spatial influences on urban retail environment and urban geography. Obviously, there is a strong need for a study exploring changes in retail structure and its influences in urban spaces so that policy makers and planners could take into consideration and help restructuring of this transformation process better. For this purpose, the study explores if the ongoing restructuring process of retailing and its possible geographical consequences can be modeled using a dynamic spatial interaction model as a device to be able to predict the future transformations.Doctoral Thesis Detection of Environmental and Urban Change Using Remote Sensing and Gis(Izmir Institute of Technology, 2007) Tarhan, Çiğdem; Çelik, Hüseyin MuratThis thesis is an example of how land use changes could be detected via high resolution remotely sensed data in GIS environment. In order to perform .change detection. IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20, 50 % and 70 %. Additionally, four different change detection algorithms have been applied, which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques.In this context, the primary objective of this thesis is to detect environmental changes regularly using RS and GIS in order to obtain up-to-date information about the urban areas.The secondary objective of the thesis is to compare the existing techniques with the newly developed GUI for change detection of environmental changes and to discuss the improvement in the overall results using information obtained with different detection techniques.The hypothesis of this thesis is to develop a new GIS based change detection system. Thus, it would be realized in the GIS environment efficiently and overlaid the results with digitized data in the same environment.Keywords: Remote Sensing, GIS, change detection, urban data, Izmir.
