Visibility graphs and landscape visibility analysis [PDF]

open access: yesInternational Journal of Geographical Information Science, 2001
Visibility analysis based on viewsheds is one of the most frequently used GIS analysis tools. In this paper we present an approach to visibility analysis based on the visibility graph. A visibility graph records the pattern of mutual visibility relations in a landscape, and provides a convenient way of storing and further analysing the results of ...
