Visibility and topography

Sjögren has analysed the visibility of the passage graves on Falbygden (Sjögren & Persson 2001, Sjögren 2003). In these studies it is concluded that the graves are not located in places with maximum visibility, but on the contrary the locations can be characterised as being hidden. This analysis answers the questions of what areas are seen from the passage graves (and in reverse, from where it is possible to see the graves). To further problematise these calculations it is possible to calculate what can be termed as background visibility. The background visibility will provide a indication of how high or low visibility is in the surrounding landscape.
