“…Nowadays, GIS, remote sensing, and three-dimensional technologies are applied to quantitative assessments of landscape visual impact, broadening the research scope and reducing errors in assessment results [18][19][20][21]. GIS's functions in geographical data management and spatial analysis can handle various processes such as extracting different spatial regions, calculating features, and identifying critical locations [22][23][24]. Conducting a direct overall visual impact assessment of architectural heritage, which often involves large areas with interconnected courtyards and intricate spatial complexities,poses great challenges.…”

The selection of viewpoints is a crucial aspect in conducting visual impact assessments of architectural heritage. To address this issue, a quantitative viewpoint selection method based on GIS spatial analysis is proposed. The first step involves defining the factors that influence the selection of viewpoints for architectural heritage. Next, the city’s historical architectural areas are divided into units based on courtyards. Subsequently, a candidate set of viewpoints is constructed by extracting the skeleton lines and characteristic points of sub-regions. Finally, following the principles of viewpoint selection, the method achieves the selection of viewpoints for the visual impact assessment of architectural heritage. The Forbidden City is chosen as the practical area for implementation, and the results demonstrate that the viewshed coverage range in the architectural heritage area is as high as 96%. It represents that this approach for visual impact assessments of architectural heritage is more grounded.
