ÖgeA model to utilize emerging ICT for revitalizing under-valued public open spaces in urbanscape: Investigating spatial video projection(Graduate School, 2023-07-24) Najjar, Lima ; Başkaya Türer, Fatma Ayçim ; 502162602 ; Landscape ArchitectureAs the 21st century unfolds, there is a chaotic interaction between rapid urban development, emerging information, communication technologies (e-ICTs), and natural dynamics. In the last decade, digital technologies have advanced at an unprecedented pace, reflected in contemporary cities' spatial experience. In addition, due to the COVID-19 pandemic, serves as a catalyst for digital e-ICTs interventions in daily life, the dependence on digital mediums in communications between people increased in a noticeable way. Hence, there is a need for an update in spatial planning and design approaches. Accordingly, this study aims to provide an approach (model) for utilizing e-ICT to deal with contemporary spatial planning and design issues. This thesis addresses the existence of a considerable number of neglected, under-valued public open spaces (UVPOSs) within densely populated urban environments. These spaces are used well below their carrying capacities despite being in good physical condition. UVPOS threatens urbanscape quality, including its environmental, social, economic, and aesthetic aspects. Even though UVPOS can have destructive effects, revitalizing these spaces can contribute to sustainable urbanization. To find quality urban public spaces in today's dense cities, UVPOS revitalization is considered a priority. In the context of UVPOS, a particular existing and developing digital e-ICT called spatial video projection (SVP) is investigated as a potential tool for revitalizing UVPOS. Spatial video projection covers digital information and communication technology that uses video projection on a surface to provide immersive experiences. In this study, e-ICT is defined as either existing information and communication technologies (ICTs) used in an emerging manner or emerging technologies that have not yet reached their maximum potential. A public open space with certain characteristics may be viewed as under-valued by a specific society but not by another. Therefore, this research focuses on a particular area of study. It descends from the city scale of Istanbul to a specific area of the Golden Horn. This research aims to provide a model that involves a theoretical, analytical, and practical framework. Accordingly, the thesis is divided into three phases: Phase 1: Identifying and linking the research's three main pillars UVPOS, UVPOS revitalization, and SVP (Chapter 2), and locating the research topic in the international research landscape (Chapter 3). Phase 2: Providing a comprehensive insight into Spatial Video Projection relevant to the research topic (Chapter 4). This also includes SVP models that have potential for UVPOS revitalization which are drone-based SVP and the mobile pedal SVP (Chapters 5 and 6). Phase 3: designing and developing a multi-level analysis and decision support making framework to examine the study area (Istanbul - Golden Horn) (Chapters 7, and 8). The theoretical framework consists of phase one and phase two. The analytical and practical framework consists of phase three. In this regard, a mixed methods approach includes quantitative and qualitative methods used to achieve the objective of each chapter. For the first and second phases, a systematic literature review, bibliometric analysis, and a guided extensive search were conducted. For the third phase, an extensive guided search, open-ended interviews, questionnaires, and a multi-criteria analysis benefitting from ArcGIS were implemented. This thesis is designed in a hybrid format. Some chapters consist of published articles, while the others are in a normal chapter format. A sum of five articles were published based on this thesis topic. There are three articles that were accepted in peer-reviewed academic journals classified as Q1, Q2, and Q3. Chapters 3, 5, and 6 represent these articles. There is a minimum of two articles that also will be sent for peer review soon. One article is formulated from chapters 2 and 4 and ready to be sent for peer review. The other ones are from chapters 7 and 8; the work on them is in progress. The first section of chapter 7 represents a conference paper. Another conference paper also based on this thesis was published and it is included in Appendix A. Details about each published article are mentioned in each chapter. A project based on the current thesis gained the opportunity for implementation in an official event called "Kamusal Alanda Dijital Sanat" The organizers of this event are the Istanbul Planning Agency, Istanbul Metropolitan Municipality, and the Amberinteractive platform. This project is explained in chapter 7, section 7.2.2. In its overall composition, this thesis provides a comprehensive approach to studying an e-ICT for revitalizing UVPOS within a specific study area. It also develops processes for forthcoming use as in chapter 3 and chapter 8. Chapter 3 provides a distinct bibliometric step-by-step guide to locate an emerging topic in the landscape of international literature. Chapter 8, however, provides a process to develop a decision support tool to identify UVPOS and those that are suitable for revitalization by SVP for the case of Golden Horn. The process provided by this chapter can be used to develop a similar decision-support tool for other case studies. The model (approach) provided by this thesis lays a foundation for future research and practices. This thesis is practice-led in its nature, and it contributes to the debate surrounding smart cities and sustainable developments.
