Abstract:

Two methods for allocating territories to settlements are presented in text books on geographic information systems in archaeology: (i) site catchments based on straight-line or alternatively on cost distance and (ii) Thiessen polygons. The exploitation territory or catchment of a settlement is a circular area for the straight-line distance. The catchments of a set of contemporaneous settlements may overlap and unoccupied areas may result. This does not happen with Thiessen polygons: The territory allocated to each settlement is a tile with all tiles covering the total study area. We explore refinements and a combination of these methods by applying them to settlement data on historical maps covering part of a hilly region in Germany. Comparing the results to boundaries on the historical maps shows limits and potential of these methods. Some alternative approaches for reconstructing boundaries or territories are discussed shortly as well.
