The current urban centre of Rome is built upon up to ten metres of anthropic layers formed between the
Early Bronze Age, when the Capitolium was first occupied, and the present days. These layers represent
an inestimable record of the events (buildings, demolitions, collapses, fires, floods, etc.) that shaped
the appearance of the eternal city. However, most of time the investigations take place near or under
contemporary historical or modern structures, which made the excavations very complex from a technical

The survey of archaeological monuments presents particular needs and difficulties. Such surveys must in fact be as complete, geometrically correct and accurately geo-referenced as possible. These needs, however, often face problems of difficult accessibility, the need for rapid timing and complex logistical conditions. The latest generation of mobile phones are equipped with ultra-high resolution cameras up to 100 megapixel.

The terrestrial photogrammetric survey allows to acquire geometric characteristics of objects quickly and with handy and inexpensive hardware. Traditionally, these measurements require some hours of time between the choice of the acquisition points, the setting up of the camera, the survey of the topographic support network and subsequent processing of the acquired data.
