This thesis approaches the issue of Viewshed Analysis and how it can impact the understanding of a medieval environment. Centered on the High Medieval period of Cilicia, in what is today Southwestern Turkey, the precision of Viewsheds in a complex terrain is evaluated, and the role of the fortifications in the environment is expanded upon. The maps that were generated for this thesis demonstrate that the use of free datasets must be done with caution, and that the use of more than one dataset is crucial in trying to create a clearer picture of the environment. The examination of four separate sets of fortifications within the region leads to new questions about the role of fortifications in the region, as well as a better understanding of what groups such as the Armenian Cilicians and the Knights Templar were doing in the High Medieval period. Finally, conclusions are made regarding the future impact of GIS based studies, and how they can help scholars understand Ancient and Medieval landscapes.
