“Discretizzazione” and Data Analysis at the Time of “Total Survey”

Abstract

The chapter contains considerations and methods of analysis of data acquired using modern surveying technologies, applied to cultural heritage. Three case studies are carried out. They are different in type of monuments, aim of survey and survey techniques used. The large amount of data acquired through innovative techniques of photographic survey and laser scanning requires an adequate process of “discretizzazione”. It will change an uncritical “total survey” into a selective and effective analysis and communication process. An excess of information could distract from the actual purpose of survey, and it could provide the illusion of a comprehensive understanding of the monument. Actually, the real knowledge does not come from the amount of data acquired but from the ability to analyze them, to relate and communicate to potential users.
