Geomatic training experiences for a high vulnerability cultural heritage item.

The plan of Architectural documentation is the basic platform on which the CH protection and development process is founded; it embraces the historical analysis, the metric survey and the graphical representation of the object. It covers a primary importance in order to achieve very many objects: the comprehension of cultural values through the study of historical sources; the morphological and geometrical data collection and interpretation for the object representation. The latter is the frame on which we can organize the diagnostic tests, build the restoration plan and the communication and dissemination of his cultural values. The achievement of the know how in the field of the architectural and environmental survey is an important part of the curriculum in faculties of Architecture. The basic courses in this field of study (an integrated course named Topography/Metric Survey/IT and the course of Photogrammetry) approach to the main methods and the modern techniques of metric survey and at the same time the students will be provided of the basic knowledge for the critical analysis of the historical handiworks in the different scales, from the territorial to the architectural one. In the area of the optional courses, the educational program widen to involve all data capture methodologies, including the LIDAR techniques, and systems of 3D survey data management and integration. Modern spatial data products, such as DEM and vector surface models, are used for the final rendering, where both the 2D and 3D element will be integrated. It will be also introduced the GIS environment for the storage and management of spatial information at the territorial and architectural scales. In this paper we are going to present several experiences employed during two courses of the Faculty of Architecture (Applied Photogrammetry and Digital Photogrammetry/3D scanning for CH survey, the last managed by CISDA – Architecture Interdepartmental Teaching Services Centre)*. In this training experiences the methodological contents of disciplines have been exploited to obtain the documentation of a cultural item, featured by a high risk of extinction: the decorated gypsum ceilings of the southern Piedmont
