Background, role and challenge of digitalization of architectural heritage

No doubt, the use of digital tools in the documentation of the architectural heritage has revolutionized the way in which historic places are identified, disseminated and virtually valued. However, these new opportunities bring new challenges to guarantee scientific accuracy and the reliability of the information used to document and protect the heritage sites long term and thus to ensure that these records are transmitted and are maintained for future use. This contribution is not only intended to underline the challenges, but also to offer options, taking into account the notion of efficiency requirements and how to capture and disseminate the knowledge the of heritage goods. These objectives will be achieved by taking as starting point the needs of the place from a comprehensive and participatory approach, focused on the importance of the information to understand the meaning and integrity. In this sense, it is essential also to evaluate the radius of deterioration caused by disturbances/threats and potential risks to these cultural resources. In relation to cultural heritage, the emphasis of this work is given to historic buildings and archaeological sites.
