Abstract

[automatically translated] Several operators, dealing with Historical and Cultural Heritage, are taking more and more often of advanced technological solutions offered by modern Geomatics, by way of an integration of its disciplines, the better to study, investigate and monitor a well of historical interest. Today they try new integrations with other disciplines that traditionally do not apply to the relief camp proper. This is, for example, the case of the study conducted on the Cathedral of St. John in Dubrovnik, where he started from the laser scanning survey of a portion of the church and its precious floor under which, according to a sketch of the early nineteenth century (Fig. 1) should be the burial, and then continue the study with the aid of the GPR, instrument traditionally used by geophysicists and geologists to investigate the land. This was done in order to verify the presence of underground structures but did not act with invasive investigations. The result of the GPR data, transformed into a three-dimensional reconstruction of the subfloor, was joined at the three-dimensional reconstruction of the church, made from processing of laser scanning survey data. This integration has allowed us to confirm the presence of underground structures and understand the report are the latter with the depressions in the floor of the church. Of the complete three-dimensional model has finally made a navigable version (VRML), offering a view and also an interaction to users without extensive computer knowledge.
