models were developed to identify locations of new, previously undescovered artifacts such as ancient aqueducts and citadels. The models are based on GIS analysis of currently known points to identify probable locations of similar features. Elevation,
slope, viewshed, and line of sight of currently known citadels was used to locate new Roman watchtowers.
Cost models were developed to determine optimal aqueduct routes through unexplored terrain and identify places of probable aqueduct remains. These models resulted in the discovery of several new, previously unseen ancient artifacts.
