    Abstract

    The visual environment is very essential for forming an urban image, therefore, it is necessary for authorities and urban researchers to quantify the visibility of urban spaces. To date, many traditional visibility analyses fail to take vegetation into account. With the development of LiDAR technology, there is an opportunity to use LiDAR point cloud data directly for visibility analysis. Point cloud-based visibility analysis can compensate for many disadvantages of traditional modelling and analysis methods. Such as a better inclusion of vegetation, which is used to be ignored in traditional GIS-based visibility analysis, can be implemented in point cloud-based analysis. This paper gives a brief review of related work and demonstrates the advantages of using LiDAR data for analysis, and also proposes an approach based on airborne point clouds taking in account the vegetation, then performs the proposed visibility analysis on a study case.
