A multiscale geomatica approach for the survey of historic centres main streets: the case study of Capitignano, Italy

The aim of this research is the identification of geomatics techniques and methods capable of representing historic centres in a rapid, detailed and accurate manner. Indeed, historic centres are a cultural heritage asset to be preserved, protected and conserved for future generations, taking into account the history of a community. The paper describes a geomatics methodology applied to the case study of Capitignano (Italy), one of the municipalities that was affected by the 2009 earthquake that involved numerous historic centres causing extensive damage, not only in terms of human lives but also to the cultural heritage. The integration of geomatics techniques made it possible to obtain a georeferenced point cloud that is particularly useful for the description of buildings in historic centres, both at the urban scale and at the scale of individual artefacts. In addition, it was also possible to produce orthophotos with a high geometric resolution that made it possible to identify lesions in structures quickly and accurately.
