“…The physical state of a city as a primary object of visual perception can be assessed by objective criteria -in architecture (Benedikt, 1979;R�d and van der Meer, 2009) or in city planning (Batty, 2001), for example -to find the best places (points) to view selected monuments. An objective approach takes into account general, conventional knowledge of visual perception (Granö, 1929;Bell, 1999;Daniel, 2001;Sevenant and Antrop, 2007), using the conceptual foundations and synergetic tools of Geographic Information Systems (GIS) to analyse visibility and the visual qualities of a city (Nijhuis et al, 2011a;Van Lammeren, 2011;Garnero and Fabrizio, 2015;Fisher-Gewirtzman, 2016;Lin et al, 2017).…”
