    ANALYSIS OF DOCUMENTATION OPPORTUNITIES OF CULTURAL HERITAGE SAMPLES WITH TERRESTRIAL PHOTOGRAMETRY METHODS
    (2021) Bilici, Ebru; Akay, Abdullah Emin; Uçar, Zennure; Genç, Musa
    Nowadays, as in many sectors, natural and cultural resources face the danger of extinction due to misuse and consumption-oriented life in tourism. Within the framework of the sustainability tourism principle, these resources should be determined, protected, and developed. With the advance technology, the use of photogrammetry offers new methods for surveying natural and cultural resources. In this study, the photographs of two historical sites were taken with a high-resolution handheld camera in order to evaluate the potential of terrestrial photogrammetry approach in the cultural heritage. Then, these photographs were used to develop three-dimensional models of the two sites using two different software-Agisoft Metashape and 3D Zephyr Free. For this study, two important cultural and historical heritages were selected; both located in the center of Giresun province in Turkey. The 3D models of the heritages developed using two software were compared to evaluate the capability of the software. In the evaluation process, 13 photographs for the historical door and 50 photographs for the shrine were used to generate 3D models. According to the evaluation of the models, it was observed that the model generated for the front surface of the Public Garden door provided more detailed and accurate results in both software. When these two programs are compared for the shrine, Agisoft Metashape produced a better 3D model than 3D Zephyr. The results also showed that the photographs obtained from a low-cost handheld camera could provide highly accurate and precise data for documentation of historical and cultural heritages.

    Essential Issues Related to Construction Phases of Road Networks in Protected Areas: A Review
    (Zagreb Univ, Fac Forestry, 2022) Sakar, Dursun; Aydın, Abdurrahim; Akay, Abdullah Emin
    Protected areas play an active role in protecting natural resources and wildlife habitat. These areas must be accessible within protection-use balance. For this reason, road networks in protected areas are one of the main functions of sustainable infrastructure services. The construction phases of road networks in these sensitive areas should be considered in planning within the balance of protection-use with interdisciplinary studies. Especially during the construction of the road network, it is necessary to pay attention to the construction machinery used, geotextile materials, hydraulic and ecological road structures, plantation of the slopes, fences that increase the visual quality and work schedule. Based on a related literature survey, the issues to be considered during the construction phases of road networks (i.e. road planning, tree felling and removing, excavation and embankment, subgrade finishing, road structures and surfacing) in protected areas were evaluated under nine headings. The implementation phases of these issues are important in reducing the adverse effects that will occur in protected areas. In this regard, during the construction phases of road networks, the issues to be considered were evaluated together with the conceptual indicators in terms of management, technique, economy, ecology, and aesthetics. Matters needing attention according to the sensitivity of conceptual indicators during the construction phases of road networks in and around protected areas that contain sensitive ecosystems have been identified and presented in a framework to further the discussions on this issue. Accordingly, the use of the issues to be considered in the planning and construction of road networks with conceptual indicators will help evaluate the planning phase before and after construction. In particular, it can be expected to lead to the creation of a checklist after the planning phase. Thus, the continuity of the issues to be considered during the maintenance, repair, and construction phases of the new road networks or existing road networks planned to be built in a protected area and surrounding areas will provide significant contributions to the functions of the protected areas. The main contributions may include increasing the number of visitors to the protected areas, reducing impacts on wildlife in protected areas by implementing innovative technologies, and developing alternative modes in tourism industry.

    Using GIS-based multicriteria decision support system for planning road networks with visual quality constraints: a case study of protected areas in Ankara, Turkey
    (Springer, 2020) Sakar, Dursun; Aydin, Abdurrahim; Akay, Abdullah Emin
    Protected areas are important zones due to their natural and cultural assets and their biodiversity preservation functions. Ecotourism activities in these areas have gained great importance for visitors in recent decades. Road networks established in protected areas have ecotourism-related functions, such as providing visitors with continuous access to/within these areas and offering visual richness to visitors while cruising on the roads. Road network planning that prioritizes visual quality is one of the scientific issues discussed today regarding the sustainable management of protected areas. This study focuses on planning new road networks that prioritize visual quality in protected areas and determining the optimum route that maximizes the visual quality experience of visitors. The study area was selected from the protected areas between the Kizilcahamam and camlidere Districts of Ankara, Turkey, and their surroundings. In the model application, a road network was planned using the multicriteria decision support system (MDSS) method by considering visual quality parameters. In this stage, the road network that prioritized visual quality during spring and autumn seasons was investigated. Hence, weighted linear combination (WLC) was used as a geographic information system (GIS)-based MDSS method. Then, the GIS-based network analysis method was used to determine the optimum route that provided access to the scenic viewpoints (existing and proposed viewpoints) in the study area and maximized the visual quality during both seasons. In the new road network planned by considering the visual quality parameters, the total road length was calculated as 121.21 km for the spring and 129.47 km for the autumn. The lengths of the optimum routes that allowed visitors to reach the scenic viewpoints and ensured the maximum visual quality were 30.91 km and 30.70 km on the new road network for the spring and autumn seasons, respectively. This study introduced a new methodology that utilized GIS-based decision support systems to plan a road network that prioritized visual quality and determined the optimum route with the maximum visual quality. It is anticipated that this methodology can be used for sustainable management and effective planning of protected areas to reach and protect resources with high visual quality.
