Cultural Heritage represents a very difficult subject to be handled. Despite its cross-cutting and multi-level characters (scientific, social, economic, political, etc.), nevertheless the topic can hardly be framed in a proper and comprehensive way. Any project addressing Cultural Heritage (documentation, preservation, retrofitting, valorisation and so on) actually tends to exalt a specific point of view and, therefore, to neglect potentially crucial contributions coming from different fields of expertise. Comprehensive solutions to this problem seem by now available thanks to ICT and the 3D Digitalization and Multimedia Technologies: nevertheless the more the platforms improve their multidisciplinary capabilities and interoperability, the more they need an intelligent design and an accurate control during the implementation phase. Built Cultural Heritage (as historic buildings, districts, sites, etc.) perfectly represents the wide range of situations, which have to be tackled. Any intervention, in fact, from the design phase to its realization and validation, actually deals with several different interlaced layers that together depict a "complex system". The construction of a Knowledge System represents a crucial step in correctly addressing the problem.

The appearance of 3D scanners and then, more recently, of image-based systems that generate point clouds directly from common digital images have deeply affected the survey process in terms of both capturing and 2D/3D modelling. In this context, low cost and mobile systems are increasingly playing a key role andactually paving the way to the democratization of what in the past was the realm of few specialized technicians and expensive equipment. The application of Google Tango on the ancient church of Santa Maria delle Vigne in Pratica di Mare – Rome presented in this paper is one of these examples.

La tecnologia che amplifica la realtà come pure i mezzi tecnologici di acquisizione dei dati, stanno continuando ad avere uno svilup - po difficilmente controllabile o prevedibile. Progetti di un certo interesse, nascono, si sviluppano e muoiono talvolta senza produrre risultati significativi, ma costituendosi come fasi di un processo fluido e dinamico, sul quale vengono costruite nuove applicazioni software e sistemi hardware. Allo stesso tempo, il ruolo dell'accademia sembra venire spesso scavalcato da ciò che viene sviluppato dalla citizen science: ai ricercatori non sembra più spettare esclusivamente il compito della "scoperta", quanto piuttosto la crea - zione di protocolli scientificamente affidabili sulla base di tecnologie spesso utilizzate dalle diverse comunità di citizen scientists in maniera non conforme alle specifiche per le quali erano state progettate. Il contributo propone una riflessione su questi temi prendendo come spunto due sperimentazioni dall'alto contenuto innovativo che abbracciano varie fasi del processo definito con il termine rilievo. Esse riguardano infatti da un lato un sistema hw/sw di acquisizione dati, elaborazione e comunicazione sviluppato per dispositivi mobili ( Progetto Tango ) e una piattaforma mista ROV/UAV multi - sensore dotata di sistema LIDAR e fotocamera digitale per l'acquisizione di dati in luoghi non accessibili ( Progetto Heritagebot ). ; The technology that 'amplifies' the real world as well as the technological means of data capturing, are continuing to have a development difficult to control or predict. Projects of a certain interest are born, develop and die sometimes without producing significant results nevertheless becoming phases of a fluid and dynamic process, on which new software applications and hardware systems are built. At the same time, the role of the academy seems to be often overtaken by what is developed by the citizen science. Researchers no longer seem to exclusively explore the 'discovery' domain, but rather work at the setup of scientifically reliable protocols for technologies often used by different communities of citizens in a way that does not conform to the specifications for which they were originally designed. This paper focuses on these issues taking as its starting point two experiments with high innovative content that cover various stages of the process defined by the term Survey. They pertain on the one hand to a hw/sw system of data capturing, processing and communication developed for mobile devices (Tango Project) and on the other to a mixed ROV/UAV multisensor platform equipped with a LIDAR system and digital camera for data acquisition in inaccessible places (Heritagebot Project).
