    Do Spatial Development Plans Provide Spatial Equity in Access To Public Parks: a Case With a Residential Area in Karabağlar and Buca (i̇zmir)
    (TMMOB Şehir Plancıları Odası, 2022) Öztürk, Sevim Pelin; Şenol, Fatma
    Public parks' location is one of the major factors shaping their accessibility. Many natural and physical features (e.g., topography, stream ways, street network, traffic density, road junctions, and land uses) affect walking distances from dwellings to these loca- tions. Also, the cost of access (measured in time and meter) to these locations vary among age groups with different walk- ing capacities. Spatial plans in Turkey are the documents for de- termining and implementing the allocation of parks. However, plan-making practices have limitations in considering the park accessibility by walking among different groups of dwellers. This study considers the accessibility of public parks as an issue of spatial equity. It evaluates the park accessibility at a recent spatial plan about a residential area in Karabağlar and Buca Districts of İzmir. It aims to assess the allocations of planned parks and propose potential locations for new park areas. With a point- based approach to park accessibility, the study analysis performs the Location-Allocation (LA) Analysis with multiple criteria at Geographic Information Systems. The results show that at the plan, the specified residential area has spatial inequities with park accessibility. Among the other planned public service areas, some locations can be re-planned as new park areas, which partially im- proves spatial inequities at the plan. Also, the study is an example of how to prepare and run the data for the spatial analysis of allocations of public service areas with the help of GIS in Turkey

    Gis-Based Mappings of Park Accessibility at Multiple Spatial Scales: a Research Framework With the Case of Izmir (turkey)
    (Routledge, 2021) Şenol, Fatma; Atay Kaya, İlgi
    With a concern of social needs in the redistribution of benefits of parks, recent research assesses park accessibility but usually at one spatial scale (e.g. city, neighbourhood, or park). As a case in Izmir (Turkey), this study explores how to develop research with a multi-scalar focus on park accessibility. It proposes a framework with the research stages deploying GIS-based tools. The first stage identifies park-rich, park-moderate and park-poor neighbourhoods. The second and third stages evolve in three park-rich neighbourhoods and at 112 local parks. All stages deal with preparing various socio-spatial data from online sources and field observations and assess the data according to a list of themes about accessibility and diversity. The results highlight that regardless of their high park coverages per person, park-rich neighbourhoods have multiple blocks, buildings, and parks with the features hindering park accessibility for some local groups with different walking capacities and needs. The GIS-based mappings of these features can provide decision-making tools about local parks and neighbourhood interventions.

    The Utilization of Supervised Classification Sampling for Environmental Monitoring in Turin (italy)
    (MDPI, 2021) Salata, Stefano
    In a world threatened by climate change, the need to observe the land transformation is crucial to set environmental policies. One of the most prominent issues of environmental monitoring is the availability of updated and reliable land use data. The last land-use release in Piedmont Region (Italy) is in 2010, while the most updated Normalized Difference Vegetation Index is in 2016. To overcome this limit, in this study, a supervised classification sampling has been applied on a Sentinel-2 image produced by the Copernicus Program on 29 September 2020, using Esri ArcGIS (ver.10.8 Redlands, California, US) by accessing via ONDA-DIAS services to L2A products. After land classification, three maps were generated-the Habitat Quality, the Habitat Decay, and the Normalized Difference Vegetation Index. This study aimed at classifying the environmental status in five classes ranging from critical to health with a double perspective-(i) to make a comparative metropolitan assessment between municipalities and (ii) to evaluate the quality of urban public green areas in the city of Turin while defining a different kind of intervention. Results indicate that products derived from supervised classification sampling can be applied in a wide range of applications while reaching seasonal monitoring of the environmental status and delivering just-in-time solutions.

    Bicycle Route Infrastructure Planning Using Gis in an Urban Area: the Case of Izmir
    (TMMOB Şehir Plancıları Odası, 2020) Özkan, Sevim Pelin; Şenol, Fatma; Özçam, Zeynep
    As a case study about İzmir (the third biggest metropolitan city in Turkey), this paper focuses on how to determine bicycle routes in already developed built environments of densely populated cities. To do so, it identifies how to deploy certain geographic information system (GIS) tools for analyzing multilayered spatial data not only at the city but also at the neighborhood level. When interrelating multiple characteristics of majorly topography, land use and population with each other, the study deploys mainly the overlay analysis and also network analysis as complementary to each other respectively at the city level and the neighborhood level. The results confirms that the use of these GIS tools for analyzing socio-spatial data especially at multiple spatial scales can support policy-makers’ decision-makings about route choices in the immediate future of their city even in a “data-poor” context,” such as Turkey.

    E-Planning Applications in Turkish Local Governments
    (Information Science Reference, 2010) Velibeyoğlu, Koray
    This chapter examines the pivotal relationship between e-planning applications and their organizational context. It employs various evaluation frameworks by searching explicit and implicit structures behind the implementation process. The study is largely based on the statement that 'the organizational and user dimension of implementation factors more than technical ones, constitute the main obstacles to the improvement of e-planning tools in urban planning agencies'. The empirical part of the study scrutinizes the personal and situational factors of users in the process of implementation, benefits and constraints of an e-planning implementation and planning practitioners' perception of new technologies on urban planning practice and debate. Using a case study research in Turkish local governments, the findings of this study reveal that the organizational and human aspects of high order information systems are still the biggest obstacle in the implementation process.
