ItemIndoor centrality( 2009)Indoor environments are different from other environments. There are some characteristics which are unique such as dimensionality and spatial structure. Apart from indoor centrality, research has been done to reveal the properties of centrality particularly in street networks, social networks, and biological networks. In addition, there are some indoor representations which have already been developed for different purposes such as wayfinding, behavioural science, and sociology.Therefore, this research is undertaken to investigate models of representation and apply the measures of centrality to reveal the properties of indoor environments. Different representations and betweenness centrality measures have been tested in a subset of indoor environments. The models and measures have been proven capable of revealing the properties of indoor environments such as centrality, prominency, and complexity. In addition, this research has revealed the strengths and weaknesses of both models and measures. The results of different measurements of betweenness centrality based on different representations are combined. Here, graph representations which depict space and link centralities in topological graphs is used to construct a structural hierarchy which is able to support wayfinding in indoor environments. This research contributes to our understanding of indoor centrality through the formalization of the representations and measures.
