摘要
可见度分析是应用于各个领域的基本地理空间处理任务之一。由于高分辨率空间数据的不断增加,最近的技术进步加快了视角计算的速度,并提高了其准确性。然而,标准 GIS 工具的局限性(主要是无法在完全三维的环境中进行分析,以及只能进行基于点的对象分析)阻碍了可视性分析方法的发展,而这些方法能够准确地复制人类的视角。本文介绍了一种结合 GIS 和 3D 图形软件并使用高分辨率激光雷达数据的新方法。所介绍的方法不仅解决了传统 GIS 方法的局限性,还为全面的三维能见度分析提供了新的可能性,能更好地表现真实世界的场景。所提出的方法可确保分析结果与用于进一步空间分析的地理信息系统兼容,因此有可能改进城市规划、景观管理和保护、环境影响评估、基础设施规划和发展等领域的决策过程。通过介绍一个涉及光伏农场的案例研究,本文展示了所提方法在现实世界中的实际应用性和优势。
Reaching beyond GIS for comprehensive 3D visibility analysis
Visibility analyses are one of the fundamental geospatial processing tasks applied in various fields. Recent technological advancements have accelerated viewshed calculations and improved their accuracy thanks to the growing availability of high-resolution spatial data. However, limitations of standard GIS tools, primarily related to the inability to perform analyses in a fully three-dimensional environment and the restriction to only point-based object analyses, have hindered the development of visibility analyses methods that accurately replicate human perspectives. This article presents a novel approach that combines GIS with 3D graphic software and uses high resolution LIDAR data. The presented method not only addresses the limitations of traditional GIS methods but also opens up new possibilities for comprehensive 3D visibility analyses that can better represent real-world scenarios. The proposed methodology, which ensures compatibility of the results with GIS for further spatial analysis, has the potential to enhance decision-making processes in fields such as urban planning, landscape management and protection, environmental impact assessment, infrastructure planning and development. By presenting a case study involving a photovoltaic farm, this article demonstrates the practical applicability and benefits of the proposed method in real-world scenarios.
期刊介绍:
Landscape and Urban Planning is an international journal that aims to enhance our understanding of landscapes and promote sustainable solutions for landscape change. The journal focuses on landscapes as complex social-ecological systems that encompass various spatial and temporal dimensions. These landscapes possess aesthetic, natural, and cultural qualities that are valued by individuals in different ways, leading to actions that alter the landscape. With increasing urbanization and the need for ecological and cultural sensitivity at various scales, a multidisciplinary approach is necessary to comprehend and align social and ecological values for landscape sustainability. The journal believes that combining landscape science with planning and design can yield positive outcomes for both people and nature.
