Diffusion and exploitation of artistic and cultural properties using the new geomatics technologies.

The new methodologies of acquisition of metric and thematic information on the territory, on the environment, on constructions and manufactured articles open further and new perspectives on the diffusion and knowledge of the artistic, archaeological, and cultural property. Many application fields concern the use of Geomatic in its sectors more up-to-date as: laser scanners, satellite positioning (GPS), digital photogrammetry , remote sensing from airplanes and satellites, Ground Penetrating Radar, numerical cartography and Geographical Informative Systems. An effective method for to reach the objective above described, is the realization of WebGis. A preliminary phase of work is constituted to individualization of the interest areas and the historical/cultural paths and following his tracing with instrumentation GPS (DGPS mode) filtration of the acquired data and the restitution on cartography georeferenced to use as layer of support for the GIS. GPR surveys have been carried out on the floors of ancient constructions. The aim of these investigations was to validate some hypothesis about the existence of buried structures and crypts. As part of the individualization and knowledge of the archaeological sites and the characterization of the historical manufactured articles laser scanners reliefs of the archaeological sites are realized. A tool laser scanner is an any device that, operating on the physical surface of an object, is able to acquire the three-dimensional coordinates of points in automatic way with elevated density and in real time. Just the architectural circle represents a particularly meaningful field of application since the morphological and dimensional characteristics of complex structures geometrically to , what statues, decorations , moldings or façades of historical buildings, represent often some insurmountable obstacles for the employment of the traditional techniques. Among the peculiarities that this system make particularly effective and efficient, it’s to underline, besides the meeting place time of acquisition, the enormous quantity of data and acquired information for every single scanning, the his uniformity of acquisition, but chiefly the not invasion of the technique. All the data so acquired are assembled inside a webGis. The webGis is freely a base online where the users of the World Wide Web and smartphone are able to have information around the geography, the historical places, cultural and the present structures on the place, through a clear location on map through the use of points of interest and multimedia attachments (photos of the place, texts, videos. etc). Therefore the user through the query about area and the contents receives the demand information.
