Does more mean better? Remote-sensing data for monitoring sustainable redevelopment of a historical granary in Mydlniki, Krakow

The Post-2015 UN Development Agenda includes culture and links the preservation of cultural heritage (CH) to sustainable development. In principle, sustainable redevelopment of CH should preserve historical qualities and ensure the financial profitability of the asset. Still, being a construction process, it has to be under constant change monitoring. Bearing in mind the quality of data achieved by measurement systems, TLS instruments can be used to capture 3D spatial data for cultural heritage. The authors analyse the usefulness of TLS data as the spatial database for the redevelopment and functional reuse of a historical granary. Following measurements on various stages of the redevelopment of the CH asset, TLS data undergo principally simple and rapid analyses (shape analysis, determination of the pace and scope of redevelopment, detection of conservation effort results, HBIM) to improve decision-making capabilities within the project. Contrary to the universal approach, periodic CH redevelopment scanning involves the entire structure, not merely its most valuable heritage components. As a result, not only doesthe remote-sensing data acquisition for monitoring of sustainable redevelopment of cultural heritage record the state of the revitalised building, but it also demonstrates the potential of periodic measurements as the primary source of insight into the heritage asset and the directions and quality of changes it undergoes.
