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.
Quantitative analysis of urban morphology: Exploring ethnic urban formations and structure in the city of Izmir
(Izmir Institute of Technology, 2009) Alper, Sabri; Arkon, Cemal
Urban design and planning have been mainly involved in forming and structuring our cities. In order to understand this form and structure, various methods and tools of analyses have been developed in urban morphology. Spatial analysis is of basic need within planning and one of the essential tools for anyone who wants to investigate space. Spatial analyses are also useful tools on the way to a deeper understanding of the city itself. The aim of this thesis is to develop a theoretical framework and quantitative methodology for modeling urban form and structure, in order to better understand the complexity inherent in urban environments and to generate and improve relevant knowledge for urban design and planning. Space syntax is a set of techniques for the analysis of spatial configurations of all kinds, especially where spatial configuration seems to be a significant aspect of human affairs, as it is in buildings and cities. Space Syntax is unique as an analysis tool since it allows us to objectively measure the street network configuration. To explore the geometrical features of urban form, a geometric model is utilized and a typological analysis approach will be used for the basic element of the fabric: .the building block., Quantitative measures obtained from these syntactic and geometric approaches, their relationships and interdependencies are analyzed and explored. An integrated set of measures is identified. Case studies in Izmir are selected for testing the methodology to be developed. Methodology development is concentrated on five ethnic districts at the late-Ottoman period. These are also known as the Greek, Jewish, Armenian, European and Turkish quarters of the city. By analyzing the urban form and structure of these districts, a new integrated quantitative methodology for analysis of urban morphology is presented.
