Rapid urban development has posed destructive effects on the visual quality of many cities over the past few decades. Consequently, Visibility Analysis (VA) methods have been adopted to evaluate and prevent the visual influences of the development over valuable scenes. Shiraz' strategic view of the Quran Gate, in especial, is known for its remarkable landmarks, while the visual effects of the recent rapid urban growth on the view have been a matter of concern. The future of the view is even more at risk due to the lack of synergy between the urban development plan and historic preservation regulation. Consequently, this study aims to undertake a Visibility Analysis of the height regulation of the Shiraz Development Plan on the view of the Quran Gate. In this essence, two 3D models of the study area are produced based on the existing condition and the Shiraz Development Plan scenario. By choosing seventeen key viewpoints, visibility analysis of landmarks and viewpoints was conducted. The results demonstrate the destructive visual effects of the development plan on the strategic view. It is suggested that the proposed cost-efficient methodology can minimize subjective evaluation and contribute to the synergy between development and conservation plans.

在过去的几十年中，城市的快速发展对许多城市的视觉质量造成了破坏性影响。因此，采用了可视性分析（VA）方法来评估和防止开发对有价值的场景的视觉影响。设拉子特别以古兰门的战略景观而著称，以其非凡的地标而闻名，而最近城市快速发展对该景观的视觉影响令人关注。由于城市发展计划与历史保护法规之间缺乏协同作用，未来的观点面临更大的风险。因此，本研究的目的是根据《古兰经》大门对西拉子开发计划的高度调节进行可视性分析。从本质上讲，根据现有条件和设拉子发展计划方案，制作了研究区域的两个3D模型。通过选择17个关键视点，进行了地标和视点的可见性分析。结果证明了发展计划对战略观点的破坏性视觉效果。建议提出的具有成本效益的方法可以最大程度地减少主观评估，并有助于发展与保护计划之间的协同作用。
