Linear cultural heritage landscape visual perception location model and demonstration
Appropriate visual perception location is a necessary condition for marvellous landscape experience,and rich visual perception spatial information resources will be helpful for exploring the overall perception of beautiful places.Linear cultural heritage not only contains rich resource value and profound cultural heritage assets,but also has important values in the attributes of visual landscape resources.However,the ability of the GIS viewshed computation results to characterize the visual relationship between the visual location and landscape semantics is insufficient for further carrying out the deep value mining of visual landscape resources.Based on the existing methods of landscape visual perception calculation,this study designed the landscape visual perception location model(LVPLM)for linear cultural heritage,and developed the organization method and application logic of the LVPLM dataset based on the NetCDF multidimensional raster data structure.The LVPLM dataset expresses the visual perceptual location through the two-dimensional geographic coordinates and the semantic information of the target landscape through the semantic feature point coding,and then constructs the visual relationship between the visual perceptual location and the landscape semantics,and realizes the information integration of the target landscape,the perceptual location,and the visual state.This study also designed three application modes of the LVPLM dataset,namely"drilling","slicing",and"dicing",to lay the foundation for multi-modal landscape visual perception information mining and analysis.This study selected the linear cultural heritage landscape resources of the Great Wall for empirical research,established the LVPLM dataset of the Gubeikou Great Wall,and collected visual comparison verification data through field investigation and survey,evaluated the basic credibility of the dataset,initially proved the feasibility and application value of the LVPLM model,and also provided a new data resource for the high-quality construction of the Great Wall National Cultural Park.In addition,the LVPLM model also provides new ideas for the study of the human-environment relationship from the perspective of information expression of interaction perception between humans and the landscape.
