摘要

评价历史景观保护中视觉连续性的基本指标之一是通过城市空间的顺序景观获得的视觉体验。控制有价值的视觉品质对于保持历史景观的珍贵顺序景观至关重要。行人的视觉视角和城市地标的寻路作用是历史城市视觉体验的核心问题。通过摄影调查,采用场景捕捉法对能见度分析进行评价。该方法结合了二维等观和三维视场分析,作为一种计算方法,应用于印度尼西亚玛琅的五个历史地标。场景捕捉方法通过提取地标的轮廓和分割场景中明显不同的区域,从各种接近的路径检查每个地标的顺序视图系列。随后,二维等视镜和三维视场分析研究了每条路线上的视野光谱模式。结果表明,在最近观测距离上,博爱学校大楼的能见度最高,为9.58%,而在最远观测距离上,卡尤坦甘教堂大楼的能见度最高,为0.97%。目视目击比例较大的观测距离范围为75米- 100米,最近观测距离为50米- 75米。将顺序照片映射和等视分析相结合,为管理和增强视觉体验提供了一个强大的工具,可以为城市规划、建筑设计和历史保护的决策提供信息。

Visibility Evaluation of Historical Landmark Building Using Photographic Survey Coupled with Isovist and Viewshed Analysis
One of the fundamental indicators for evaluating visual continuity in the preservation of historical landscapes is the visual experience gained through sequential views in urban space. Controlling the valuable visual qualities is essential to maintain the precious sequential view of the historical landscape. The visual perspective of pedestrians and the wayfinding roles of urban landmarks are central issues in the visual experience of historical cities. The evaluation of visibility analysis is performed using the scene-capturing method via photographic survey. This method is combined with 2D isovist and 3D viewshed analysis as a computational approach applied to five historical landmarks in Malang, Indonesia. The scene-capturing methodology examines the sequential view series of each landmark from various approaching paths by extracting the landmark's silhouette and segmenting the visibly distinct areas of the scene. Subsequently, 2D isovist and 3D viewshed analyses investigate the pattern of the visual field spectrum along each route. As a result, the best visibility rate at the closest observation distance is achieved by the Frateran School Building at 9.58%, while the best visibility at the farthest observation distance is observed at the Kayutangan Church Building at 0.97%. The range of observation distances with a significant percentage of visual sightings is from 75m - 100m, with the closest observation distance ranging from 50 - 75 meters. Combining sequential photo mapping and isovist analysis provides a powerful tool for managing and enhancing the visual experience, which can inform decisions on urban planning, architectural design, and historical preservation.

期刊介绍: For investigation regarding the impact of planning policy on spatial planning implementation, International review for Spatial Planning and Sustainable Development (IRSPSD International) seeks to learn from researchers in an integrated multidisciplinary platform that reflects a variety of perspectives—such as economic development, social equality, and ecological protection—with a view to achieving a sustainable urban form. This international journal attempts to provide insights into the achievement of a sustainable urban form, through spatial planning and implementation; here, we focus on planning experiences at the levels of local cities and some metropolitan areas in the world, particularly in Asian countries. Submission are expected from multidisciplinary viewpoints encompassing land-use patterns, housing development, transportation, green design, and agricultural and ecological systems.
