Topografia di Roma antica: ipotesi per una sistematizzazione dei dati a valenza topografica

This paper is a synthesis of an experimental study on ancient topography and town-planning in a historical quarter of Rome, Trastevere. The focus is on methodological aspects, and in particular on computerized applications. Thy have been used, at first, to speed up the input and the management of data, but the results deeply influenced the methods and the logical course of the research itself. The study can therefore be considered also as a proposal for a modular application to other urban contexts. Traditional sources of information were taken into account, as in any study on ancient topography, including the archaeological map (concerning both visible and bibliographically documented elements) drawn on the basis of present-day cartography, literary and archival sources and historical cartography (from Forma Urbis Severiana to Catasto Pio-Gregoriano). In addition to the study of some important methodological consequences of this approach, the results are outlined of having applied computerised procedures of cartographical transformation, not previously adopted in any archaeological framework.
