    Detection of Environmental and Urban Change Using Remote Sensing and Gis
    (Izmir Institute of Technology, 2007) Tarhan, Çiğdem; Çelik, Hüseyin Murat
    This 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.

    A Method for the Analysis of Lot- House Relations in Ottoman Housing Patter
    (Izmir Institute of Technology, 2011) Saf, Hayriye Oya; İpekoğlu, Başak
    Defining the lot - house relations in the Ottoman housing pattern is significant for determining the authentic settlement characteristics of the pattern. In this context, this study, based on a morphological analysis method, claims the necessity of analyzing the pattern in terms of house-lot related parameters. Geographic Information System (GIS) software has been used for the visualization of analysis results. The aim is to create a set of rules between the house and lot. The inferences to be obtained as a result of this study can be used as a design guide in the field, in which method is to be applied for creating a conservation plan for a project. The study area selected was Edirne Kaleiçi Region. The method was created through a three-phase system. The variables were specified in the first phase; and then analyses that would display the structural relations were determined. The implementation and evaluation phase was the third phase of the method. As a conclusion of examining the lot - house relations within the parameters set, the thesis has identified the morphological relations with respect to the main plan types, sub plan types and lots. On the condition that this method is applied in other cities, it would be possible to comment more on the lot - house relations for the Ottoman house pattern.

    A Methodology for Geographical Information Systems Based Participatory Decision Making Approach
    (Izmir Institute of Technology, 2001) Yiğitcanlar, Tan; Arkon, Cemal
    Geographical Information Systems (GIS) to come up with better planning can be utilized. But unless the final decisions contain strategic and participatory decisions and are indeed an improvement upon previous solutions and are in fact turned into actions, using a GIS will just not necessarily increase the cost of the planning activities. In this thesis a new approach, which is called "Geographical Information Systems Based Participatory Decision Making Approach (GISbPDM)" is proposed to overcome current planning problems and also to answer most of the debates about traditional GIS. GISbPDM employs three basic components in its body. Collaborative GIS is the first component of GISbPDM and represents the spatial decision support system and makes new GIS trends available - especially Public Participation GIS - for public, urban planners and decision makers. Strategic Choice Approach is the second component of GISbPDM and it is a sophisticated technique for making decisions and developing action plans in situations with many options and uncertainties in a participatory manner.Computer Supported Collaborative Work System (CSCW) is the third component of GISbPDM and has an involving structure - by cooperative work and participatory design supported by computers - for utilization of the collaborative and participatory decision models. The system architecture of GISbPDM has quite a simple mechanism. GIS including the local and central databases is used for data manipulation, visualization, queries and interactive sketching on an easily accessible platform. Strategic Choice Approach is the policy and decision-making model that works interconnected to this GIS platform.Accordingly participants can visualize the alternatives, submit them to the decisionmakers and other participants, allow them to modify the alternatives and create their own proposals. The participation can be realized in different levels such as information participation, collaborative work, public participation and elite participation. Proposed system architecture has an encouraging power for participatory planning and besides CSCW helps in increasing participation in all levels.

    Integrating Case Based Reasoning and Geographic Information Systems in a Planing Support System: Çeşme Peninsula Study
    (Izmir Institute of Technology, 2009) Çınar, Ali Kemal; Serim, Muharrem Erkal
    Urban and regional planning is experiencing fundamental changes on the use of of computer-based models in planning practice and education. However, with this increased use, .Geographic Information Systems. (GIS) or .Computer Aided Design.(CAD) alone cannot serve all of the needs of planning. Computational approaches should be modified to deal better with the imperatives of contemporary planning by using artificial intelligence techniques in city planning process.The main aim of this study is to develop an integrated .Planning Support System. (PSS) tool for supporting the planning process. In this research, .Case Based Reasoning. (CBR) .an artificial intelligence technique- and .Geographic Information Systems. (GIS) .geographic analysis, data management and visualization techniqueare used as a major PSS tools to build a .Case Based System. (CBS) for knowledge representation on an operational study. Other targets of the research are to discuss the benefits of CBR method in city planning domain and to demonstrate the feasibility and usefulness of this technique in a PSS. .Çeşme Peninsula. case study which applied under the desired methodology is presented as an experimental and operational stage of the thesis.This dissertation tried to find out whether an integrated model which employing CBR&GIS could support human decision making in a city planning task. While the CBS model met many of predefined goals of the thesis, both advantages and limitations have been realized from findings when applied to the complex domain such as city planning.
