Combining Viewshed and LiDAR analysis to search for  unknown Roman Fortifications on the Nijmegen Moraine

This thesis explores the evidence for Roman archaeology on the Nijmegen moraine east of the city. This area is poorly researched compared to the city of Nijmegen in the west and the newly discovered auxiliary forts in Germany to the east. Roman fortifications were hypothesized to have existed on the higher peaks of the moraine, offering a commanding view over the wider area and connecting west to east. An analysis of the available literature indicates this part of the moraine might hold more Roman archaeological remains than is currently known, including villae and fortifications on the high peaks. In an attempt to predict and locate these, the AHN3 height map of the Netherlands is used for a visibility analysis and LiDAR visualization analysis of the area. The visibility analysis shows that several high peaks, most notably the Duivelsberg, are ideal locations for a watchtower which could act as a missing link in a signalling system between the fortifications in Nijmegen and those...Show moreThis thesis explores the evidence for Roman archaeology on the Nijmegen moraine east of the city. This area is poorly researched compared to the city of Nijmegen in the west and the newly discovered auxiliary forts in Germany to the east.

The visibility analysis shows that several high peaks, most notably the Duivelsberg, are ideal locations for a watchtower which could act as a missing link in a signalling system between the fortifications in Nijmegen and those in Germany. LiDAR analysis indicates that several areas on the moraine likely contain undiscovered archaeological remains, including World War Two battle remains, prehistoric barrows, and urnfields. The research also demonstrates the strengths and shortcomings of using these digital methods to locate new archaeological remains. It is concluded that the moraine is a highly attractive area for future archaeological research into Roman Nijmegen or other periods.Show less
