This paper proposes a GIS quantitative method for simulating dispersed distribution of sites in a landscape. A certain number of sites might have escaped archaeological detection due to the adverse surface visibility conditions experienced during field survey (the so-called missing sites). As regards early Roman colonial landscapes of central-southern Italy, these surface visibility factors were traditionally seen to be so dramatic as to have allegedly hampered the detection of the conventionally expected dispersed and densely-settled colonial farm landscape. In this paper the regional and site-oriented field survey conducted in Venosa (Basilicata, Italy) is used as a case-study to simulate a large amount of hypothetical early colonial sites. The aim of this theoretical exercise is to show how the rural dispersed settlement pattern expected by the conventional theory could appear on a map, and to visually highlight the divergence between survey data and conventional spatial expectancies.

This paper proposes a predictive theoretical model of ancient human movement in the Alpone Valley (VR). The aim of this study is to calculate, using GIS tools, the optimal pathways to move from an archaeological site to another considering a series of frictions, like topography or land use, that can affect movement. The reliability of these virtual ancient paths is tested using a mathematical function of metabolic energy created in Visual Basic editor: it facilitates the choice of the best frictions for the model to simulate the archaeological landscape and its possible human perception. The results are compared to verify if there is any correlation between present and past pathways using topographic maps. This GIS methodology is useful for an archaeological survey because it gives a preliminary presence probability of ancient paths in a landscape.
