2. We have also explored some facets of visibility (as well as many other factors) through GIS. This work was carried out in London by Andrew Dufton for his dissertation for the MSc in Geographical Information Systems at UCL (Dufton 2005). On the basis of a GIS for 746 recorded Neolithic sites of the Tavoliere, Dufton recorded that aspect (the facing direction of slope) showed a preference for sites to face north east, east, and south east. The whole landscape of the Tavoliere has this tendency, in that it is based on a series of terraces sloping down from the Apennines to the sea, but the frequency distribution of archaeological sites shows a greater tendency to face in these directions compared to the natural landscape. When looked at in more detail, it emerges that most sites in the central and northern plain face east, while a large proportion of those in the south depart from this pattern and face north, towards the Gargano. This suggests that the Gargano may have been an especially important landscape feature for the Neolithic occupants of the plain. We intend to look further at this issue in future research, investigating possible environmental factors, such as wind direction, as well as human experiential/cognitive factors.
