    Gis-Based Determination of Suitable Agricultural Areas and Comparison With Current Land Use, the Case Study of İzmir
    (Izmir Institute of Technology, 2022) Ekinci, Özge; Demirkesen, Ali Can
    Agricultural production is the main source of life for humanity. In order to the protection and proper use of agricultural lands are of great importance. İzmir has a high potential in terms of agricultural areas. There are three basin areas within the provincial borders and fertile agricultural areas where the continuity of agricultural production can be ensured. With the effect of urbanization and population growth, the settlements expanded towards agricultural areas. For the correct use, sustainability and efficiency of agricultural lands, the most suitable areas in terms of agricultural production should be analyzed correctly. This study was carried out to determine the most suitable areas for agriculture in İzmir. The study considers a Geographic Information System GIS-based approach. The combination of multi-criteria decision analysis (MCDA) and GIS can be used in the process of generating solutions for complex planning problems. In the first stage of the study, the criteria were weightlessly overlayed, and a result map was obtained. In the second stage, weights were obtained for each criterion using the Analytical Hierarchy Process (AHP). Suitability analyzes for the study area were obtained by weighted overlay analysis using GIS. Environmental characteristics, soil characteristics and economic factors were taken into account while performing the suitability analysis for agricultural areas. The same criteria were used for both suitability analyses. As a result of the comparison between the two maps, a resultant map obtained by the weighted overlay method was found to be more reliable, and the results were compared with the current situation. In the current situation comparison, Great Lowland Protection Areas, 1/100000 Scaled Environmental Plan, and Law No. 5403 are discussed. When the comparisons were made, the areas that differed with the current situation were determined. It is seen that the agricultural lands obtained as a result of the suitability analysis are spread over wider areas compared to the current situation.

    An Assessment of Spatial Relationship Between Lung Cancer Incidence Rate and Quality of Urban Life: Izmir Case
    (Izmir Institute of Technology, 2013) Özkan, Sevim Pelin; Saygın, Mustafa Ömür
    The study assesses spatial clusters of lung cancer incidences within Izmir province on the basis of districts and also neighborhood using an objective sets of quality of life indicators. Lung cancer data, approximately 18.000 cases, were acquired from the Izmir Cancer Registry Center (ICRC) between the years of 1992-2007. Cases have been confirmed in terms of accuracy by World Health Organization (WHO). As objective indicator data, point source air pollution data acquired from the Izmir Metropolitan Municipality database between the years of 1993-2007. Besides, socio-economic statistics data were obtained from Turkish Statistical Institute (TSI) regional indicators (2000,2007) and Izmir Metropolitan Municipality city health profile (2007). The datasets were used to determine whether there is a significant spatial relationship between cancer case density and environmental contamination. This thesis uses spatial statistical models and Geographical Information System (GIS) techniques to analyze population-based cancer incidence rate. Additionally, Age Standardized Incidence (ASR) of the lung cancer was calculated. Spatial autocorrelation technique was performed to investigate local distribution of lung cancer. Results of the study suggest that spatial clusters of lung cancer were detected in geographic locations with low level environmental quality and high level socio-economic profile. Then, the results are discussed in terms of life quality and environmental quality of Izmir. The results of this study are useful for interdisciplinary researchers, epidemiological studies, policymakers and governmental agencies in terms of health and environmental assessment, regulation and control of spatial strategies.

    A Cad-Based Modeling for Dynamic Visualization of Urban Environments in Piecemeal (incremental) Growth
    (Izmir Institute of Technology, 2002) Alper, Sabri; Serim, Muharrem Erkal
    Visualization is inherent to the conduct of urban design as a direct connection between the designer and three dimensional reality of urban settlements. Visualization of urban environments and urban design projects is vital, since most designers prefer to understand place and context through visualization. The reasons for visualization in urban design can be classified under three headings: .visual thinking, design communication and testing mechanism. Digital revolution. has improved computer use in urban design, as in many other fields. Dynamic computer models can present an ideal environment to visualize the change in respect to time. Digital tools are much more efficient than conventional methods in explaining the growth and change of urban environments. Especially, incremental growth requires features not found in .static/analog. media. Christopher Alexander and his colleagues, in their book .A New Theory of Urban Design., tried to justify their ideas about piecemeal growth by an experiment. The analog methods, such as physical models, two-dimensional diagrams, have been used to conduct the experiment and to convey their ideas about the design process. This thesis tries to produce a .dynamic/digital. model that could be utilized in their experiment instead of static/analog methods. Spatial data should be considered as dynamic, or changing identities rather than as simple, static features. Time is an example of a dynamic component of a spatial data set. Recent technological developments are increasing computer hardware and software capabilities so that this dynamic aspect of data can be accounted for by today.s systems. Dynamic data have not been a great concern in digital technologies for many years, but today changing patterns and dimensions are becoming more important.
