Modeling urban structures using graph-based spatial patterns
(IEEE, 2007-07) Doǧrusöz, Emel; Aksoy, Selim
We introduce a new method for modeling the spatial arrangements of geospatial objects. As opposed to the existing approaches that are based on classifying images using pixel level methods, we propose to use objects as textural primitives and exploit their spatial patterns. First, the primitives are detected using spectral and morphological processing. Then, these primitives form the nodes of a graph where the neighborhood information is obtained through Voronoi tessellation of the image scene. Next, this graph is clustered by thresholding its minimum spanning tree. Finally, the resulting clusters are classified as regular or irregular by examining the distributions of the angles between neighboring nodes. Experiments using Ikonos images show that the application of the proposed model where buildings are used as the primitives and building groups are automatically classified as organized or unorganized can extract valuable information about urban development. © 2007 IEEE.

Rethinking social inclusivity: Design strategies for cities
(ICE Publishing, 2011) Afacan, Yasemin; Afacan, S. O.
Cities have become more fragmented due to the increasing urbanisation of many parts of the world. There is more inequality and a growing complexity of social life in cities that leads to social exclusion and increasing social differentiation. This study approaches social inclusivity within the context of universal urban design and defines it as a vehicle for promoting human wellbeing, environmental wholeness and principles of participatory democracy. Mat urbanism - an urban form concept that is more organic and fluid than other urban forms and models - is proposed, alongside a universal design approach, to achieve the goals of sustainable communities and enhance quality of life. The relationship of mat urbanism to the features of high-quality environments and sustainable developments is questioned and illustrated with simple diagrams. The paper concludes with the importance of universally designed sets of regulatory practices regarding sustainable architecture and urban development - from individual buildings to the district and city-scale level. The contribution of this study is not only to explore the potentials of Smithson's configurations theoretically but also to open new means through which towns and cities can be planned in the future in order to promote social inclusivity, environmental responsiveness, sustainability and universal urban design.

Sabiha Gökçen Havaalanının kuruluşu
(Bilkent University, 2022) Sır, Arda; Ulu, Batıkan Aybey; Ergin, Emir; İneci, İrem Sude; Pattabanoğlu, Hatice Ceyda
For Istanbul, Turkey’s busiest city in terms of air traffic, Sabiha Gokcen International Airport (ISG) has significant importance. It was founded as a part of Advanced Technology Industry Projects (ITEP) at first and stayed as the only part of the project that came to life after ITEP was cancelled. It was decided to be built in 1997 and opened in 2001. Airport Management and Aviation Industries Inc. (HEAS) is responsible for the airport’s establishment process. As a second airport founded in the metropolis Istanbul, ISG lightens the passenger load of Ataturk Airport.

A socio-spatial analysis of urban transformation at a neighborhood scale: the case of the relocation of Kadifekale inhabitants to TOKİ Uzundere in İzmir
(Pergamon Press, 2015) Demirli, M. E.; Ultav, Z. T.; Demirtaş-Milz, N.
Particularly in the last two decades, urban governors have presented urban transformation projects as ideal solutions to help low-income urban residents improve their living conditions. However, the way they have been carried out and their consequences mean that these projects do not, in most cases, bring the expected improvements. Most projects involve relocating residents to new, more peripheral districts of the city, which causes social isolation and certain socio-spatial incompatibilities between their previous and new habitats. Using a case from Izmir in Turkey, this study aims to analyze such socio-spatial incompatibilities in the lives of low-income residents that are caused by relocation within the framework of urban transformation projects. One of Izmir's earliest inner-city gecekondu neighborhoods, Kadifekale was chosen by Izmir Metropolitan Municipality as a site for urban transformation due to the risk of landslide in the area. Before the start of the project, the neighborhood contained 7324 housing units accommodating rural-to-urban migrants, mainly from the southeast of Turkey. This urban transformation project aimed to relocate at least some of the inhabitants from their homes in Kadifekale to recently constructed apartment blocks in the TOKI˙ Uzundere Public Housing Project on the periphery of the city. Although many residents were reluctant to exchange their houses for new apartments, some were persuaded to move to TOKI˙, which was presented as the ideal solution by the municipal officials. This study critically evaluates the Kadifekale urban transformation project, particularly with regard to the relocation of some Kadifekale residents from their one- or two-story houses in Kadifekale to apartment blocks on the periphery of the city. The analysis is based on a comparison between the socio-spatial experiences of migrants in Kadifekale and their recent experiences in Uzundere and the possibility of certain incompatibilities in these two experiences. The argument aims to demonstrate the changed conditions of social life and daily life practices as a result of altered spatial properties at a neighborhood scale: their use of outdoor spaces, the meanings they attributed to neighborhood space ("intimacy of place" within categories of sensual (visual and olfactory) recognition), and their sociospatial network. The argument draws both implicitly and explicitly on Henri Lefebvre's spatial triad and De Certeau's conceptualization of tactic versus strategy as the major conceptual inspirations for this study. © 2015 Elsevier Ltd.

Urban development process of built environments in metropolitan areas in Turkey: case study of angora settlement, Ankara
(American Society of Civil Engineers, 2012) Balta, M. T.; Tekel, A; Tekel, H. T.
The built environments of metropolitan areas are rapidly changing in response to urban development dynamics. The nature of the urban built environment continues to be influenced by the conflicting interests and expectations of various entities involved in the process of development planning and implementation. The formulation and implementation of urban development plans in Turkey is guided by the statutory provisions of the country's planning system. This process has led to piecemeal implementation through partial plans and plan amendments in metropolitan areas. This article attempts to determine how the private sector in metropoles in Turkey shaped the built environment in Turkey after 1980. Influence of neo-liberal policies and a partial planning approach set by a free-market economy instead of a comprehensive planning approach shaped urban space. As a capital, the urban development of Ankara has mostly been shaped by partial planning approaches and implementations and uncontrolled developments, especially on the southwest axis of the city's metropolitan area. For this reason, one of the largest settlement of southwest Ankara is the Angora Settlement, which has been selected as the case study. Examining the entities who play a part in the urban development process is important to control its consequences. In this article, the case of Angora Settlement is used to question the planning process and entities in the development of urban built environments, and studies this settlement to identify and question which entities determine the components of the built environment in the urban development process. In particular, this paper captures the dominance of the structural interests of the private sector in shaping Angora's land use pattern, which is important because it reveals the uncontrolled growth dynamics in developing countries. © 2012 American Society of Civil Engineers.
