ABSTRACT
In archaeology, the study of the territory on a large scale has traditionally encountered the difficulty of having to record suitably the delimitation of archaeological sites, emergent structures or historical landmarks, either with a pure scientific purpose, or with the aim of establishing protection areas in urban planning documents. The principal difficulties that the on-site researcher has to face are (cf. Campana & Francovich 2006, Coloso et al. 2006): – The exact positioning of the limits of sites, structures and landmarks
in the map; even using the potentiality offered by Global Positioning
Systems (GPS), it is not always easy to be located in the cartography, and errors are frequent (Topouzi et al. 2002);
– The possibility of transcription errors with the on-site data, particularly if the transcription was made by a different researcher;
– The prohibitive prices of GPS and FDCA technologies.
