Integrated geomatic techniques for georeferencing and reconstructing the position of underground archaeological sites. The case study of the Augustus sundial (Rome)
A large part of the archaeological remains still to be discovered and excavated are not in remote and depopulated areas of the earth but are often beneath urban centres that have buried them with centuries of debris and later constructions. Excavating in these contexts is much more complex than digging in rural or sparsely inhabited areas because of the constraints imposed by existing buildings and infrastructure.
